Laguna Grande

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.

Fun way to spend an evening
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 Boat Ride With Round Trip Transport
Realllly nice and fun crew/guides - everyone was so friendly, funny and helpful! Kayaking at night was a cool and unique experience. We needed to use a tarp to see the bioluminescence so be prepared for that if it’s not pitch black out. Wish we could’ve seen the glow for longer but it was def worth the trip!

Bioluminescent Bay Night Kayaking Tour in Laguna Grande Fajardo
Magical! We had a group of 10. The whole experience was top notch from beginning to end from the sounds of nature to the natural bioluminescent beauty! It was extremely well run, the guides were knowledgeable and fun! A must see if you are visiting Puerto Rico as there are only two other places in the world to see this natural phenomenon!

This experience was phenomenal. A trust walk type exercise while kayaking. The guides were friendly & excellent at handling stress. Very much appear to Like their jobs and each other. Rafael, Mike, Neitzche,(sp?), Big Cal and 2 more were wonderful. Lester was our driver. Punctual and kind. His vehicle is far from fancy. It works. Once in a lifetime opportunity Thank you

Bioluminescent Bay Night Kayaking Tour in Laguna Grande Fajardo
Very cool kayaking through the jungle in the dark …the bioluminescence part was just ok you couldn’t really see it glow like the pictures but you saw something

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.
