Experience Puerto Rico’s Bioluminescent Bay in Lajas

Your visit to Puerto Rico isn’t complete until you discover the natural wonders of one of our bioluminescent bays. Join us on an unforgettable tour to see this unique phenomenon.

La Parguera Reserve, set aside by the Department for Natural and Environmental Resources, is recognized as a world-class treasure. Within it is found one of the world’s few bio bays, where there are sufficient microscopic bioluminescent organisms to produce light visible to plain eyesight. Just jump in to activate the show.

We start our journey with a pick-up at your hotel lobby. It’s a two-hour scenic drive from San Juan to Lajas. The highway cuts through the mountains north to south and vice versa. Immerse yourself in the perspective of the south side of Puerto Rico. Once in Lajas, we embark with our captain just in time to watch the sunset over the horizon.

After dusk, our captain enters the bio bay and provides the scientific reasons for the effect. Then you can enter the water to swim and frolic about (approx. 30 min. swimming time).

Life vests, bottled water, and beer are provided.

We drop you off at your hotel around 11 p.m.

Experience the Magic of Bioluminescent Bay Boat Tour

Have you ever looked up at the stars and thought about flying all the way up just so you can feel them for yourself?  Well, you are not alone. Even though the chances of you hopping in a rocket and making your way up to outer space are astronomically low, Puerto Rico has an equally entrancing alternative. Yes, that’s right, bioluminescent bay!

These hypnotic waters will save you from a whole lot of neck craning just to star gaze. Why look up when your dreams are already at your feet?

The bad news is there are only five bioluminescent bays in the world. The good news? Well, Puerto Rico is home to three out of five bioluminescent bays in the whole world! These bays can be found in the cities of Lajas, Fajardo, and Vieques. The bay at Lajas is the only one you can swim in, and the one at Fajardo is the easiest to get to from San Juan.

The Science Behind Bioluminescent Bays

Bioluminescent bays are a result of microscopic, single-celled organisms that are called dinoflagellates. Dinoflagellates can be found throughout the ocean. These organisms can grow in large quantities (by large, we mean thousands and thousands) that are enough to produce a ‘glow in the dark’ effect when they are stimulated by movement. So, unlike any normal body of water, when you paddle through these bays, the organisms and everything they come into contact with are bound to light up in an enchanting neon blue-green tint. You will literally swim through stars!

The Bioluminescent Bay Boat Tour Experience

You can take a tour through the most visited Laguna Grande in Fajardo. Technically, this is the only one that is classified as more of a lagoon than a bay due to its narrow and long canal that leads to the luminescent water. Alternatively, you can enjoy a tour on a motorboat at La Parguera. You will be provided with equipment so you can dive in and swim after dark, or take a glass-bottom boat ride so you can spend the night in marvel. Vieques offers the brightest bioluminescent bay in the world. Enjoy a tour through these waters and be in awe of just how concentrated the water is thanks to our neon friends.

To make this experience all the more enjoyable, here are a few tips to bear in mind. It is best to avoid nights where there is a full moon. This is to ensure that the water is darker hence, intensifying the glow. It is also a good idea to call a couple of days in advance to confirm that the brightness of the bay is above 30% in the days before your tour. Dress comfortably in clothes suitable for kayaking as you will not be allowed to swim in any of the other bays apart from La Parguera. Additionally, try not to use hand creams, bug repellents or any other lotions that may pose a threat to or harm the organisms.

Depending on the bay tour operator you choose, prices may vary. However the normal price range is about  $48 to $76 per person. Tour operators tend to offer two trips per day; one at sunset and the other around 7:30 pm. The sunset tour provides you with the opportunity to soak in the environment and have a look at the mangroves as you kayak. As can be expected, the later trips give you the chance to really see the glow of our new favourite micro-organisms.

Other Attractions in the Area

A good place to stay nearby is Vieques. This area is centrally located. If you are on a budget, you can stay at the Turtle Bay Inn or La Jamaca. For a small and cosy stay, you can opt for Casa Bonita Inn. If you are more accustomed to the life of luxury, or you simply want to pamper yourself, the Copamarina Beach Resort and Spa is a great option for you to consider.

If you are looking for ideas on what to do with your time, either before or after your visit to these enchanting bays, you can visit bars, restaurants, and beaches. Some good places to eat are the Biekes Bistro, Buen Provecho, Lazy Jacks, and so many others. The options are endless!

If you have opted to stay in Fajardo, some good places of accommodation are the Suenos del Mar which is budget friendly, the El Conquistador Resort which is a little more expensive, or the luxurious St. Regis Bahia Beach Resort.

Yes, you read right. A memorable night of witnessing the supernatural is yours to be had all with a simple booking. Hurry down to these beautiful bioluminescent bays and swim amongst the magical lights. Absorb the scenery, learn about the science behind the magic and be captivated. Do not miss out!

Enjoying La Parguera’s bio bay in Lajas municipality

Lajas is a southwestern municipality of Puerto Rico located between Cabo Rojo and Guánica, on the southern coast of the island facing the Caribbean Sea. Lajas is home to another bio bay – La Parguera bioluminescent bay (La Bahía Fosforescente).

Bioluminescent bays are uncommon due to their delicate nature and surrounding ecological issues. The phenomenon of luminescence occurs irregularly in tropical warm waters around the world. Puerto Rico, luckily, is one of a few places that has three well-preserved bio bays . The healthiest two are located in Fajardo and Vieques . La Parguera has the least (compared to the other two) number of dinoflagellate microorganisms that glow when water is agitated. Nevertheless, La Parguera with its glittering waters is still one of the biggest tourist draws in the south-west of the island. Seeing the lagoon’s water glow in a pitch-black night is a dazzling and breathtaking experience.

Upon arrival at La Parguera, you will notice numerous bio bay tour vendors. There are a couple of ways of getting into the La Parguera bio bay – using a small private boat or a large glass-bottom vessel. With a smaller boat, you will get more flexibility in terms of timing. They may even let you go for a swim in the bay. The trips start at dusk, around 7 pm. Reservations are usually not required – simply come to the dock and speak to one of the operators.

Boats depart from La Parguera pier. While getting into the bio bay, you will pass narrow canals surrounded by mangroves. If you want to fully enjoy the phenomenal experience of a tropical phosphorescent bay, it’s best to come on a moonless night . Yes, this is not the most healthiest bioluminescent bay in Puerto Rico, but it can be relatively bright. Once again, nature is unpredictable and there are plenty of factors that affect bio bay’s performance – anything from the moon phase to weather and tides.

Just arrive at dusk, take one of the local boats to Bahía La Parguera, and enjoy thrilling dinoflagellate watching. Bioluminescent microorganisms in the water put on a surreal glowing show, sparkling like fireflies in the blackness of the sea.

6 Best Bioluminescence Tours In La Parguera Bio Bay, Puerto Rico (2024)

• Bioluminescent Bays
• La Parguera Bio Bay

Puerto Rico has three bioluminescent bays.

La Parguera Bioluminescent Bay is the only one you are allowed to swim in.

I first visited this bio bay when I was a child, and I have taken these tours at least a dozen times since. 

Below are the 6 best tours in La Parguera:

1. Glass bottom catamaran tour

As the name says, this is a catamaran with a glass bottom.

On this tour, you don’t get to swim in the bioluminescent bay.

When you arrive at the bioluminescent bay, the captain briefly explains the bio bay. Then, t hey collect a bucket of water, and you can agitate the water with your hands to activate the bioluminescent organisms.

After that, they send some crew members to swim under the catamaran. As the crew members agitate their arms and legs, you can see how the water starts to illuminate through the glass bottom.

This tour is excellent and inexpensive, perfect for the elderly and younger family members. 

You can book this tour with the Fondo de Cristal Tour .

2. Bio bay swimming tour

La Parguera Bioluminescent Bay is the only bio bay in Puerto Rico where you are allowed to swim.

Some tours allow you to get in the water and activate the bioluminescence yourself by moving in the water.

The tour operator will take you on a boat to La Parguera’s Bioluminescent Bay.

You will get a brief explanation of what makes the water glow, and then you will swim in the bio bay, spending about an hour in the water.

This tour is physically demanding, but if you can swim, I highly recommend it.

To book a swimming tour in the bay, visit Parguera Eco Tours.

3. Snorkeling and bioluminescent bay tour

They call this tour the best of both worlds.

At 4:00 PM, they take you to snorkel some of the best shallow reefs in Parguera. A PADI professional will accompany you on the trip to ensure your safety.

At 6:00, they will serve you Puerto Rican empanadas and your choice of soda or local beer.  After you have eaten, they will take you on a boat to the bioluminescent bay.

At the bio bay , they will provide you with a mask and a snorkel.

This tour lasts half an hour and allows you to experience bioluminescence with an underwater view.

You can book this tour with Paradise Scuba Snorkeling PR .

4. Nightime bio bay kayak tour

If you like kayaking, this is the tour for you.

On this tour, they take you to the bioluminescent area on one of the company’s vessels, towing the kayaks with their boat. 

The tour operators will provide you with a life vest, a glow stick, and a sound device.

You will be allowed to go in the water and swim in the bioluminescent bay . These tours take two hours from start to finish.

Large families or groups should call in advance for scheduling purposes.

To book this tour, go to the Parguera Water Sports website.

5. Private bioluminescence tour

Do you want to experience La Parguera’s bio bay more intimately?

In that case, this tour is the right one for you.

This tour has a six-passenger maximum. The tour operator will take you to bio bay in a 19-foot boat. You are allowed to swim so you can experience it firsthand.

Tours use a skiff which is a shallow, flat-bottomed open boat with a sharp bow and square stern.

The US Coast Guard regulates all marine vessels, and they have the following regulations: 

The maximum weight the boat can carry is 1,400 pounds. The ladder to get in and out of the boat might not hold more than 250 lbs.

For more information about booking this more intimate tour, contact Alelí Tours .

6. La Parguera bio bay tour from San Juan

Do you want to go to the bio bay from San Juan but don’t want to drive 5 hours round trip?

Then a tour from San Juan to La Parguera is suitable for you.

These tours take care of everything. They will pick you up at your hotel and drive you to La Parguera . Once you arrive, you will get appetizers. 

You will then board a private boat that will take you to see the floating homes and the mangrove keys at La Parguera.

After sunset, they will take you to the bio bay.

You will get bottles of water and local beers on the boat. On the bioluminescent bay, you will be allowed to swim, and as you agitate the water, it will start to glow.

After you have experienced the bio bay, they will take you back to your hotel in San Juan.

Participants are instructed to stay in the safety of the shallow areas of the bay and to use life vest at all times, There will also be time to go in the water and float near the boat so you can see the bioluminescence glowing around your body.

Visit the Fajardo BioBay in an Electric Boat

2/22- BioIsland is making reservations and a wait list for tours….If you want to go on an electric boat, check them out!

Puerto Rico is blessed with a natural phenomenon that is found in only a few other places on earth — it has 3 year-round bioluminescent bays (or BioBays). There is La Parguera in Lajas in the south-west of Puerto Rico, Mosquito Bay on Vieques and, the most visited one, Laguna Grande in Fajardo in the north-east of Puerto Rico.

I am so happy to say that there is now an eco-friendly way to visit Laguna Grande without having to kayak or walk. Bio Island is the company that offers an electric motor boat tour that is both safe for the environment and fun.

Bio Island’s Boat

The boat they use has a duel motor. The motor it has been approved by the DRNA. Bio Island tour is really eco-friendly. They use a really quiet Minn Kota electric motor that is mounted on the Honda low emissions gas motor, so it can be interchanged by a flick of a switch. They use the gas motor until they get into the channel and then switch over to electric. The boat is a small Carolina Skiff , so it has a very low profile — not much deeper than the kayak bottoms.

There was always a question about the other electric boat company following the DRNA rules and whether they used the electric motor, so when I went on this tour with this new company, I did it anonymously. I really watched and asked lots of questions and I am happy to say they followed all the DNRA rules and have a few ecologically friendly ones of their own too (like no eating/drinking in the boat- so no trash ends up in the water). And they are even applying to get "Blue Flag" status for their boat/trip. Yea!

Our Trip into Laguna Grande

The tour was really nice (and relaxing!). I went out with some older guests, who were staying in our rental , who were unable to kayak or walk very far, and the Vieques trip was out of their budget. This trip was perfect for them!

We left from the Las Croabas boat ramp, where they helped us into the boat. Since we were all together, we could all talk, interact and learn the whole time. Throughout the tour Captains Ron and Charlie told us about the boat/engine, the other boats docked in the Las Croabas area, the Biobay, the fish, the dinoflagellates, and they even had some jokes to tell — lots of good information. Charlie and Ron were such gentlemen, too — when it started to rain, they gave their jackets to the older ladies in our boat. I think they offer great customer service.

The tour lasts approximately 1½ hours. Since we got through the channel and into the lagoon quickly, we were able to spend about 45 minutes in the biobay itself — swirling our hands in the water to see the glow, smacking the boat to scare the fish and watching their glowing paths, talking and enjoying the stars and the evening. On the return trip, we stopped to wait while the many kayaks made their way through the channel, so we didn’t collide with them.

The bay is connected to the ocean, so as the tides change, it does get to be low tide and the channel gets shallow. The motor is the deepest part on their boat, so they lift it to avoid hitting the bottom and stirring up the silt. On the way back, after we got out of the channel and into the marina, there is a very shallow area. So Captains Ron and Charlie had to get out of the boat and walk the boat across the sandbar. We just sat there and cheered them on! Both before and after the trip, they had chips and water/soda for us to enjoy.

I really liked this tour. I think it is a great option for people who are unable to do one of the kayaking tours, such as people with small kids, elderly, handicapped, etc. or people who just don’t want to kayak. It is easy and eco-friendly. The only negative is that space is limited — they can carry a maximum of 6 people per tour.

The cost is just a little more than the kayak trips. Reserve your trip online.

If you're happy, let them know it — Don't forget to tip your your bartender, tour guide or trip operator if you enjoyed yourself. Gratuities are appreciated and typically aren't included in the price they charge you.

They have 2 boats available for tours, so group 1 and Group 2 are at each time. They do 1-2 trips per night, depending on the season and demand. Check trip times on their reservation page (changes with season). They operate Monday through Friday, may will start Saturday tours when demand picks up. They take Sunday night off.

Minimum age for kids is 2 years old. It really depends on the size of the child and if an infant life vest fits securely.

Allow about 1½ hours for the trip, plus a little time before and after.

You can call them at 787-422-7857 for more information.

You can visit their web site for more information or make an on-line reservation! Click on the date (even if green) to see available openings.

As with any trip into any of the biobays, be sure to check our biobay/moon calendar to make sure the moon will be favorable for viewing the biobay on the night you want to go.

Las Croabas boat ramp is located at the end of Road 987 in Fajardo.

BIOLUMINESCENT BAY KAYAK & SWIM TOUR

Quick Details

• Tags Ages: All Ages
• Hour Glass Duration: 2 Hours | 2.5 Hours

Nighttime Bio Bay Kayak Tour!

On this tour, we take you on board one of our vessels, towing the kayaks all the way to the lagoon area. On our way to the bioluminescence area, we navigate at proximally 50 – 75 meters from the coast at all times. The sea conditions on our way are mostly flat, with no currents, light wind, or breeze since it is a protected area by outer reefs and mangroves.

Once inside the lagoon and cleared from other commercial boats, you can board your kayak. You are instructed to kayak in a specific shallow area giving us a 100% advantage in terms of safety. You are also instructed to use a life vest at all times, as well as glow sticks and a sound device. You are allowed to go in the water and float near the boat so you can experiment with the bioluminescence face to face.

After your kayaking tour, we get the group back on board and go back to the dock. The whole tour lasts about 2 hours.

Large families should call to make arrangements. We can incorporate a bigger boat and better pricing.

Parguera Water Sports has developed this new service in order to keep families together while complying with physical distancing norms. This charter is managed solely by the captain. No additional crew on board.

Epic Outdoor Adventures In Puerto Rico

O ften described as an outdoor enthusiast's paradise, Puerto Rico offers up a number of epic outdoor adventures — several of which cannot be found anywhere else in the world. While it has all the qualities of a tropical paradise, Puerto Rico is also a U.S. territory. This, along with a very ample airport in the capital city of San Juan, makes it incredibly easy for Americans (and others) to travel to, as it requires no passport for U.S. citizens and the official currency is the U.S. dollar.

Those who head to Puerto Rico in search of adventure will quickly realize it is not just a single island. Rather, it is an archipelago bounded by the Caribbean Ocean to the southwest and the Atlantic Ocean to the northeast. The islands of Puerto Rico are mountainous, with miles of coastal shorelines, inland rivers, lagoons, lakes, and bays. It is also home to the only tropical rainforest within the U.S. National Forest system . These factors combine to truly make it a paradise for outdoor enthusiasts, providing a variety of unique and epic outdoor adventures, some of which may seem almost surreal.

Hike In El Yunque National Park

El Yunque National Forest takes in close to 29,000 acres of tropical rainforest in the northeast of Puerto Rico. Hiking along the 24 miles of trails contained within the park offers adventurers a chance to see a number of plants and animals that are not commonly found elsewhere. Although there are a handful of creatures you should beware of while adventuring in El Yunque , overall the rainforest is safe — especially compared to other tropical rainforests throughout the world.

Like all national parks, El Yunque offers a variety of outdoor activities. There are more than a half dozen designated swimming areas in the rainforest and stopping at one can be a great way to cool down during a hike. A number of these swimming spots are accompanied by waterfalls, which only adds to the exotic feel of El Yunque. Hikes can also be interspersed with stops at any of the dozens of lookout and observation locations scattered throughout the park. The Yokahú Observation Tower in particular allows for stunning views over the rainforest canopy.

Tour operators are also active in El Yunque and offer activities like zip-lining and ATV tours. Camping, unfortunately, is not possible at this time, but will soon be available again. The campsites have been under repair, but the park plans to reopen numerous sites in the near future.

Paddle The Bioluminescent Bays

Paddling in a bioluminescent bay is a rare, epic, and somewhat otherworldly outdoor adventure. Why so rare? While bioluminescent events can occur in a variety of marine environments, there are very few saltwater bays that consistently glow. Sources vary on the exact number of these illuminated water bodies, however, what is known with certainty is three of them are in Puerto Rico. This certainly makes Puerto Rico the premier destination for anyone wishing to witness the phenomena of a glowing estuary caused by microscopic single-cell organisms called dinoflagellates. 

The three bioluminescent bays found within Puerto Rico are scattered through different regions. Mosquito Bay, considered the brightest bioluminescent bay in the world according to Guinness World Records , is situated on the island of Vieques, which is about 8 miles off the eastern coast of mainland Puerto Rico. Laguna Grande, found near the town of Fajardo on the eastern side of the main island, is perhaps the most accessible of the three, as it is only about an hour's drive from San Juan. Finally, there is La Parguera in Lajas on the southwestern portion of the main island.

Kayak rentals and tours are available at all three locations. There are many mistakes paddlers can make , but not taking a nighttime paddle on one of these bioluminescent bays while visiting Puerto Rico would be one of them.

Explore The Underground River

On the northwest side of the mainland is a somewhat hidden, yet surprisingly impressive natural feature -- Rio Camuy, the third-largest underground river in the world. Just as impressive as the size of Rio Camuy is the fact it was able to remain hidden for so long. It is actually a very recent archeological discovery –- at least by modern people. The cave system and accompanying river were not discovered until 1958. Subsequent exploration has revealed evidence that the indigenous peoples were familiar with the cave system, but otherwise, this massive labyrinth of caves and the river that runs through it was hidden from the modern world until more than a decade after World War II.

To date, the entire cavern system has yet to be explored. However, it is known to contain at least 200 caves stretching over an impressive 10-mile distance. Archeologists believe the system may actually contain at least three times as many undiscovered caves. There are more than a dozen known entrances to the cave system, but only a portion of these are open to the public. Today, the 268-acre Rio Camuy Cave National Park affords visitors the opportunity to experience this extraordinary geological landform for themselves, though it's essential to go as part of a tour.

Snorkel Along The Beachfront

It is hardly a surprise that a chain of islands surrounded by clear tropical waters full of colorful fish and marine life is an ideal place to snorkel. However, it is still somewhat surprising just how prime access there is for snorkelers and free divers in Puerto Rico. Each of the three main islands –- the mainland, Vieques, and Culebra –- offers unbelievable snorkeling opportunities.

The majority of people visiting Puerto Rico stay in San Juan, and from there they are able to snorkel from just about any beachfront. However, Escambron Beach is considered the best area in San Juan for consistently good snorkeling conditions, as its waters are protected by several natural rock formations. It is also home to Escambron Beach Marine Park . Tres Palmas Marine Reserve near Rincon, Seven Seas Beach near Fajardo, and La Parguera Nature Reserve on the southwestern coast are other snorkel hotspots on the main island. From Fajardo, snorkelers can also take a water taxi to Cayo Icacos, an uninhabited island within the La Cordillera Nature Reserve. On the smaller islands of Vieques and Culebra, visitors will find plenty of worthwhile snorkeling along almost every beach. It's also possible to join one of the numerous snorkel and dive tour operators for those who don't wish to go the DIY route.

Go Fishing For Fun And Adventure

Puerto Rico is surrounded by water and criss-crossed by numerous rivers and streams. So, it is little wonder that Puerto Rico offers such a myriad of fishing opportunities. There are numerous guides and charter boats willing to treat anglers to a day on the water, whether it be offshore in search of dorado, wahoo, tuna, and billfish or inshore for tarpon or snook.

There are also plenty of self-guided angling opportunities in Puerto Rico for those who want to make sure they take advantage of the best time of day to go fishing . Light-tackle anglers and fly fishers will have plenty of opportunities to target tarpon and snook within the bays, lagoons, estuaries, saltwater stretches of river, and along the beachfront. Anglers fishing on the beachfront can also catch a variety of reef fish, including snapper and barracuda. However, there are not just saltwater angling opportunities to be had in Puerto Rico. Those who choose to fish the freshwater portions of Puerto Rico's rivers and streams can expect to catch peacock bass, tilapia, and a variety of panfish.

I sat silently in my kayak, one hand swirling the water outside the boat. With each gentle swish, a miniature constellation of underwater “stars” twinkled around my fingers. In the kayak beside me, a woman spun her paddle in the water and gasped at the tiny explosion of light. Ahead of me, the comet-like streak of green in the water indicated a fish swimming near the surface. That’s the magic of Bio Bay tours.

I’d come to Isla de Vieques, off Puerto Rico’s main island on a kayaktrip in its world-famous bioluminescent bay. The experience was everything I’d hoped for — a stroke of luck, given how poorly I’d arranged my trip. Getting the most out of a bio bay tour requires a lot of advance planning, and, in the case of Vieques, more cash than you might expect.

Here’s what I wish I knew before making the trip.

13 Things I Wish Somebody Told Me Before Taking the Fajardo Bioluminescent Bay Tour in Puerto Rico

1. bioluminescence is surprisingly common.

Much like fireflies do on land, single-celled, water surface–dwelling organisms called dinoflagellates, a type of plankton, can emit light underwater. They aren’t the only marine organisms that glow. Some 1,500 species of fish are known to luminesce, as well as certain types of squid, jellyfish, worms, and crustaceans. Many use bioluminescence as lures for food or mates, or to confuse predators.

Although dinoflagellates are microscopic, they often form large colonies. The human eye doesn’t detect the bioluminescence when a water body is still. But when disturbed, such as by wind that ripples the surface or the slicing of a boat hull through the water, our eyes translate the light wavelengths into glow-in-the-dark sparkles and zigzags of green or blue-green.

2. Puerto Rico Has Three Bioluminescent Bays

The planet currently has five ecosystems where dinoflagellate concentrations are high enough to consistently cause this bioluminescent phenomenon. Puerto Rico claims three of them where Bio Bay tours are organized.

In Fajardo, along the east coast of the main island , Laguna Grande is the most trafficked of the trio. It’s not as bright as the others, but at only an hour by car from San Juan , it’s the easiest to get to. This also makes it the most touristy of the bunch.

A few of the better-known Laguna Grande tour operators include:

• Eco Adventures
• Kayaking Puerto Rico
• Yokahú Kayak Trips
• Puerto Rico Bio Bay Tours

In Lajas, on the opposite corner of the main island, La Parguera is the least visited of the three bays. At about 2.5 hours from San Juan, it’s a much longer drive than Laguna Grande, but a worthwhile stop if you’re visiting the western side of Puerto Rico.

Some Bio Bay tours allow swimming in La Parguera. Because chemicals in bug repellents, sunscreens, and body lotions can kill the phytoplankton, you’ll need to shower before joining a tour that includes swimming or diving through the bio bay.

Try one of these La Parguera tour operators:

• Parguera Eco Tours
• Bio Bay Tours
• Kayaking Parguera
• Alelí Tours

The granddaddy of all bioluminescent bays, and the brightest in the world, is Mosquito Bay in Vieques. Although Hurricane Maria devastated the island in 2017, Mosquito Bay’s dinoflagellate population has, miraculously, doubled since then. On a dark night, you’re almost guaranteed to see something spectacular.   

Tour operators on Vieques include:

• Abe’s Snorkeling
• Black Beard Sports
• Vieques Kayaks Bio Bay
• Jak Water Sports

3. Booking A Tour Can Lead To Unexpected Expenses

You can rent a car and drive to Laguna Grande or La Parguera. Mosquito Bay isn’t connected to the main island, so you’ll need to take a ferry (about $40 per person) or small plane (about $120 per person) from Ceiba, or fly directly from San Juan (about $130 per person), to get there. Depending on the time of year, ferry and flight service may or may not be available after 7 p.m. Residents of Laguna Grande are given preference on the ferry, which means you could get bumped from an especially full voyage.

In addition, many bio bay kayaking tour operators require an address where you’ll be staying on the island in order to complete booking. Since cars aren’t allowed on the ferry to Vieques, you must rent a car or line up a taxi ride once on the island.

The short story: It’s best to plan an overnight stay on the island.

Between our flights, taxi, accommodations in the least expensive Airbnb we could find, and the tour itself, my husband and I spent about $450 on this portion of our kayak trip. Allow for more costs if you plan a day trip to El Yunque National Forest – the only tropical rainforest in the U.S. National Forest System.

We chose Abe’s Snorkeling for our excursion. The sea life kayaking experience was very good overall, although the tour operator, like an airline, oversold their 7 p.m. tour. About a dozen of us were bumped, with no notice, to the 9 p.m. slot. For our trouble, our guide offered each pairing of people a refund on one ticket.

4. Almost Anyone Can Do It

Bio bay kayaking is appropriate for most levels of ability. The water is usually calm, and paddling is done at a laid-back pace, mostly in two-person boats. Because you’re kayaking in the dark, it’s important to follow your tour guide and his instructions and stick close to your tour group. This could be tricky for travelers with vision or hearing impairments. If you’ve got grandkids in tow, ask about age restrictions.

5. Know Your Moon Cycles, And Book In Advance

You might be able to book a tour on the fly, but I wouldn’t risk it. Most fill up several months in advance, especially during the high season.

Although Puerto Rico’s bays luminesce year round, you’ll have the best experience on a dark night. Kayaking during a new moon is preferable because the glow percentage is usually higher. Using a moon phases calendar will help you chart out the best time to go.

Most operators don’t even run tours 3 days before or after a full moon. We didn’t realize this when we booked our Puerto Rican vacation. Fortunately, the final night was just beyond the full-moon window.  

The day before or the morning of your excursion, call your tour operator to check on the bay’s brightness; it should be a minimum of 30 percent. In addition to the moon, tides and water temperature affect how much color you see.

6. Ask About Clear-Bottomed Boats

Some tour companies offer clear-bottomed boats, which allow for a unique look at the bioluminescence directly underneath you. This isn’t the default option, so be sure to ask if it’s important to you.

7. Dress To Get Wet

Wear comfortable clothing, such as shorts and a T-shirt, preferably made of tech or quick-drying fabrics; some splashing is normal during any kayaking outing. Pants and shorts with zipper pockets are useful for storing a credit card, in case you want to stop at a restaurant or bar on the way back to your hotel or Airbnb (no need to take a full wallet or cash). Sturdy walking sandals, knit sneakers, or aqua shoes are all good choices for footwear.

Don’t count on being able to stash extra clothing or shoes with the tour operator; take only what you need.

8. Skip The Sunscreens And Skin Lotions

Wash your hands and feet before the trip, and don’t apply any moisturizer, serums, or lotions. You’ll be allowed to dip toes and fingers in the water, but chemicals from common skin products can kill the dinoflagellates.

9. It’s Okay To Take Your Phone

Your bio bay tour guide will tell you to leave your cell phone behind, ostensibly because its camera won’t be able to capture the glow. This may be true, or it may be an effort to reduce the sharing of images, which might, in turn, lead to a reduction in tour purchases. I regretted listening to this advice. I think I could have used my cell phone camera in manual mode and gotten sufficiently long exposures to get quality and free photos of some of the luminescence.

Bottom line: There’s no harm in taking your phone, as long as you seal it in a floating dry bag, and wear it on a lanyard around your neck. Just be aware that if you accidentally overturn your kayak, you might have trouble retrieving the phone in the dark. And don’t spend all your time taking pictures. The best part of the experience is staying in the moment and enjoying the display.

10. Be Prepared For A Wild Ride

The drive out to the bio bay is a bit like riding a roller coaster without a seat belt. Our bus driver clearly had been making this drive for years, and he knew every pothole and curve in the road — and took most of them at a robust clip. In the dark. I had to pry my fingers out of the seat upholstery after he swerved through small herds of the island’s free-roaming horses. Fortunately, he didn’t hit any.

Pro Tip: About those Viequense horses: They’re not wild, even if tourism brochures and resorts market them as such. All are owned by residents and are set free to browse the island’s grasses when not being used as transportation. Sadly, these beautiful animals are frequently killed in road accidents. If you rent a car, drive slowly and cautiously.

11. Keep Your Expectations In Check

Nature is fickle, and an evening of 100 percent glow might be followed by one of less than 30 percent. To make matters worse, all promotional images of Bio Bay tours are Photoshopped. While it is a breathtaking sight, you will not be engulfed in a happy blue halo, nor will the water light up on its own. What you’ll see is more akin to an underwater shower of glitter every time you or your tour mates dip an oar or hand into the bay.  

12. Bio Bay Tour Without Kayaks

Is there another means of transportation to get to the bay? Yes, there is now an eco-friendly way to visit Laguna Grande without having to kayak. Bio Island is a company that offers an electric motorboat tour that is both fun and safe for the environment.

They use a really quiet electric motor approved by the DRNA. A low-emission gas motor is used until the boat gets into the channel and then they switch to electric. Being a small Carolina Skiff, the boat has a very low profile, not much deeper than the kayak bottoms.

13. Bio Bay Is Virtually Impossible to Photograph

This is because the illumination is not originating from the water itself, but rather the dinoflagellates in the water. The images that you see online are captured using long exposure techniques, and don’t look anything like the real thing. 

However, the elusive nature of capturing the Bio Bay on film doesn’t mean that it is at all subtle. If you go out when the bay is particularly active you’ll never experience anything so stunningly surreal and beautiful. You should only hope that someday you’ll be lucky enough to see it again.

Is Bioluminescent Bay Kayak Trip Worth The Extra Trouble And Expense?

That’s a big yes. Although I can’t speak for Laguna Grande or La Parguera, kayaking Mosquito Bay was as close to magical as an outdoor experience can get. The bay is wide open and hushed, and even with other groups of kayakers out on the water, it felt like we were the only ones. Paddling was relaxed over the hour and a half we spent out on the water. Even the inexperienced kayakers had a great time.

Because I’d read up in advance and scaled my expectations, I wasn’t disappointed. The bioluminescent glow was actually more pronounced than I figured it would be, with miniature fireworks going off each time a boat pushed through the water. It wasn’t the neon blue radiance shown on tour websites, but it still felt otherworldly, like holding a galaxy of tiny stars in my palms. Aside of Puerto Rico, you can also see bioluminescent water on the Southern California coas t.

When Is the Best Time for a Kayak Trip in Bio Bay in Puerto Rico?

Generally, the best time for a kayak trip is around the new moon when there is less moonlight in the sky to interfere with the glow. Many factors affect how visible the bioluminescence is on any given night, including cloud cover which may help to block the moon and its light.

Why Is the Bio Bay Closed for Three Days Each Month During the Full Moon?

The Department of Natural Resources in Puerto Rico does not allow any tours during those days every month so that Bio Bay can get some  “rest” from human interaction.

Can I Go to See the Bio Bay in Puerto Rico on My Own?

No. Bio Bay is only open to tour companies with DRNA permits, not individuals. It is safest to go with a reputable and insured tour company with a tour guide who will explain the biology of the fragile ecosystem there for you.

Can Small Children Go On Bio Bay Tours in Puerto Rico?

Yes, tour companies take infants and young children on their Bio Bay tours. Infant and child life vests are available and the kids will be seated in a parent’s lap in the kayak. Inexperienced kayakers are advised not to kayak with kids.

What Should I Bring for My Bio Bay, Puerto Rico Tour?

You should bring a towel, natural DEET-free bug spray, and some kind of water shoes. For our day tours, you should also bring sunscreen and protective clothing like rash guards and hats if you like.
