Laguna Grande, Fajardo

The Basics

Visitors can set the water aglow and create a trail of light with every stroke of their paddles during guided nighttime kayaking tours. Trips are usually offered around the cycles of the moon, timed to the darkest nights. Some tours also combine kayaking with an afternoon nature walk to La Mina Falls in the nearby El Yunque National Forest.

There are only a handful of places in the world where bioluminescent plankton is consistently found, three of which are in Puerto Rico. In addition to Lagunda Grande, this natural phenomenon exists in Mosquito Bay on Vieques Island and the bay at La Parguera. Laguna Grande in Fajardo is surrounded by red mangrove trees, which are native to the surrounding El Yunque rain forest and provide vitamin B12 to the marine plankton.

Everything was perfect - from check in to the instructions, to the safety briefing, to the cool paddle through the mangrove canal, and the excellent guides on the peaceful bioluminescent bay! Thank you!

Bioluminescent Bay Night Kayaking Tour 8:00pm | Laguna Grande, Fajardo
Paddling through the dark mangrove tunnels was completely surreal. The bioluminescence was fantastic. We went on a clear night with no moon, so we got to enjoy the stars as well. The guides and other staff were wonderful. The equipment was in good shape and clean.

Good experience to see Bioluminiscent but beware of lots of mosquitoes.

Natural One- Laguna Grande Bio Bay Kayaking
Make sure to spray lots of bugs spray. There's a lot of mosquitoes for pre-departure. During the Kayaking, you'll definitely get wet since you will be Kayaking in a dark lagoon. Our was 7:45pm and we could hardly see each other. Once you are in the main area for the bioluminiscent, you will not be able to take pictures of the bio bay. But. We enjoyed it and the staff were very organized and nice staff.

Kayaking at night is great

Natural One: Laguna Grande Bio Bay Kayaking
Kayaking at night is pretty unique. I would recommend that you wait until the Moon is gone as it is difficult to see the bioluminescence in the water. I do appreciate the tour guide bringing a tarp to make things darker, and I do appreciate how amazing it is to save the kayak at night in a lagoon. The staff was nice, some of the people in our group were a bit rowdy, but all in all it was a good experience

Bioluminescent Bay Night Kayaking at Laguna Grande, Fajardo
Such a cool experience! The moon was too bright to see the bioluminescence but the tours had a back up plan which still made the experience amazing!

Bioluminescent Bay Night Kayaking Tour 8:00pm | Laguna Grande, Fajardo
Kayaking through was fantastic. The moonlight was to strong to see the bioluminescences, but the tour guides brought tarps. Once under the tarp you could totally see them like glitter in the water. Penil's guises where amazing.

Truly a one of a kind experience with wonderful guides

Bioluminescent Bay Night Kayaking at Laguna Grande, Fajardo
Our beloved captains Rafael, Ashley, Emely, Ahmed, AJ, & Carlos were super friendly, funny, helpful, and environmentally informative as they provided us an incredible night kayaking experience in a GORGEOUS bay/canal/wildlife reserve. Super convenient location in the Kayak Village with nice shoos & the guides had a super swift and easy check-in /safety brief set up. The stars in the bay were the most magical thing (especially the shooting star we saw!!!) and the bioluminescent ~dinoflagellates~ were arguable the most amazing thing I’ve ever seen/the 8th wonder of the world. LONG LIVE THE RED MANGROVE TREES!!!

Bioluminescent Bay Night Kayaking Tour in Laguna Grande Fajardo
The crew did an excellent job organizing everyone, explaining everything, and safety. They were friendly and made the experience fun! Paddling through the mangrove was particularly peaceful.we didn't see a lot of bioluminescence because of the moonlight, but they covered us with a tarp so we could see it better. Would totally do it again!

Bioluminescent Bay Night Kayaking Tour 8:00pm | Laguna Grande, Fajardo
Raphael, Michael and Pedro were amazing! They guided us through this tunnel of wildlife and trees very well (I was a bit freaked out about it being so dark, but we made it through!) Seeing and learning about the fish made for a great experience! I will definitely recommend this specific tour to all of my friends and family. :)

Things to Know Before You Go

  • Kayak tours typically navigate through a tunnel of mangrove trees before reaching the glowing waters.

  • Swimming in the bay is not allowed; you can swim and snorkel in the bay at La Parguera.

  • Guides will sometimes bring a cover so that the tour group can observe the bioluminescence in complete darkness without starlight.

How to Get There

Laguna Grande is located in the Las Cabezas de San Juan Nature Reserve, just off the shores of Fajardo, about 40 miles (65 kilometers) or an hour’s drive east of Old San Juan. Tours typically depart from San Juan or Luquillo, which is 9 miles (15 kilometers) away.

Show all

When to Get There

Kayaking trips frequently set out in the early evening around sunset, launching from Las Cabezas with a tour guide or instructor. The best time to experience the bioluminescent bay is when the sky is especially dark due to little or no moonlight, so try to book your tour around a new moon and avoid days surrounding a full moon.

El Yunque Rain Forest

Sometimes coupled with a tour of the bioluminescent bay, a visit to El Yunque Rain Forest is a must-do for nature lovers visiting Puerto Rico. It is the only tropical rain forest in the United States Forest Service and features well-defined walking trails, lush landscapes, and plenty of wildlife such as the Puerto Rican parrot and the Coqui frog.
