I booled through Island Kayak Rentals (IKR) and it was worth every penny and minute of time. I had never kayaked before (its pretty easy, just communicate with other person in the kayak) and while getting there is a bit of a workout its very doable (I have 2 surgically repaired shoulders, did it no problem. If youre lookin for... More

Magical! We kayaked through the mangrove forest out to Laguna Grande. Dipping our paddles and watching the neon blue water drip off of them was magical! Once out on the bay, slam your paddle onto your boat and watch the fish scatter, stirring up the bioluminescent plankton! Like fireworks in the water!

I am still in ha about how challenging yet so rewarding! When you throw water on yourself and it looks like blue neon glow sticks splattered all over you, it only glows a second or so, but bioluminescent bay wow words can not describe.... the is a must see. Just don't recommend going around a full moon.

My husband and I did the bioluminescent bay sea kayak trip with another couple in May. It was hit but not miserable. Heed the warning to use bug spray...you will need it. The educational part of the trip was fascinating! The trip back out of the big lagoon in the dark was fantastic! Watching the "glowing" fish and turtles was... More

This was an experience of a lifetime. Kayaking 1 mile and back in the dark to Laguna Grande to experience the bioluminescent bay in action. Due to an organism living in the water, when it is disturbed by the kayak oar, water, etc. the water glows like glitter. Cool to see and good exercise. The only downside was the girls... More

This was by far the most unique experience my friends and I shared on our long wknd trip to Puerto Rico. Raised in Florida, I'm familiar with the weather, food, & friendly people of PR however it reminded me very much of FL. However, our kayak trip to the bio bay opened my eyes to what PR offered; 3 of... More

We wanted to visit one of Puerto Rico's bioluminescent bays but waited too long and had trouble booking one. If you visit PR book this as soon as possible. Luckily our hotel's concierge service was able to arrange a tour with B&E Tours. They were great! Young guys with a great sense of humor and very knowledgeable. Our two teenage... More

I would recommend to take the tour that starts at 6pm. Mangroves are awesome! Never seen anything like that before. It was so cool to kayak in there. Laguna itself is amazing! I would not say pictures in web are lying. They don't. Laguna really glows brightly BUT only when you touch the water. When you look at the pictures,... More

We had read so many reviews about the bioluminescence phenomena that we thought we had to do this excursion during our visit to Puerto Rico. Since we couldn't do the one in Vieques (requires overnight stay unless you can get on a fast catamaran) and the La Parguera one wasn't considered good, so we settled on this one. Even then... More
