San Juan · BIOLUMINESCENT BAY KAYAKS
18 reviewed
Fajardo holds one of the brightest bio bays left on earth, and a moonless night turns every paddle stroke electric blue. These are the best bio bay kayak tours: which launch on the darkest nights, how long the paddle runs, group sizes and prices, plus a word on the tide and moon charts that make or break the glow.
Paddle night mangroves from Las Croabas to Laguna Grande in Fajardo and watch bioluminescent plankton glow with each stroke.
“We are in our 70’s but fit. It was a manageable workout. Bioluminescence was a bit disappointing, but the night kayaking through the mangroves was awesome. Leaders managed logistics of the large group well. We have not received the promised photos. Please send (or resend) them.”
Kayak through Fajardo’s mangroves to Laguna Grande, then watch blue-green plankton glow on a 2-hour biobay adventure.
“Our family had a great experience. We wouldn't recommend if at least one oerson in the two-person pair for the kayak doesn't have any experience. Also, if you have an odd number, someone in the group will get paired with someone you don't know. Worked out great for our group but can imagine it might be a challenge in some situations.”

El Yunque hike and night kayak in Laguna Grande with bioluminescent plankton. Pickup, helmets, lifejackets, and muddy waterfall swims.
“It was a fantastic experience especially for the activities in El Yunque. The tour guide who is also the driver is knowledgeable and took good care of every participant. I recommend the activities between rocks, cliffs, and river. The guide provided life jackets and helmets so it’s safe to do these activities. During hiking, participants need a little rock-climbing and walking in the rivers. Even not joining water activities, everyone would get wet on the way. A pair of non-slip and closed toes shoes is needed. Bio Bay kayaking, needs paddling for about 1 hour . This time we only saw little glowing sprinkles by splashing water underneath big black…”

Swim in Puerto Rico’s bioluminescent bay, taste rum from the barrel in Ponce, and enjoy tacos on an evening boat tour from San Juan.
“This tour was absolutely amazing. The hot springs were a delightful, relaxing stop. We had a delicious dinner then got on the boat for a slightly rainy sunset. The bioluminescent Bay isn't anything amazing until you get in to the water, and then it's magical. Highly recommend Cruz as a guide and this tour in particular!”

El Yunque rainforest, Luquillo kiosks, and Laguna Grande biobay kayaking in one full-day outing with pickup and guides.
“Tour company picked us up and dropped us off close to our hotel. They call to confirm the day before and 5 min before pickup. Rainforest was ok, we only saw some geckos, nice views and waterfall. It was ok to say you saw it. The kayak was fun and different going out at night but biolumenscence isn't what we expected, it was a few algae that you could see when you swirled your hand in the water. Maybe just do the bay in condado to have fun kayaking at night. The beach was terrible-maybe one of the dirtiest places I have ever been, I am not sure why this…”
