  • Discover bioluminescence at Fajardo Bio Bay
  • Enjoy a kayak tour through a mangrove forest with protected fauna
  • Explore with professional guides

Begin the tour at Kayak Village in the area of Las Croabas, Fajardo. First, learn the basics of kayaking, safety, and the rules of the nature reserve.

Paddle towards the entrance of the Fajardo Bio Bay, a red mangrove channel. Along the way, see its beautiful protected flora and fauna.

Proceed into Laguna Grande and into the sunset, where the night will fall and stars will follow in the sky and water. At every stroke of your paddle, sparkles will appear in the water, while the kayaks will create a swirl of light.
Enjoy the constellations while sitting in your kayak at Laguna Grande. Cruise back through the mangrove channel, led by your guides. At this time, night has set. The kayak’s navigation lights will guide your way as you hear the wonderful nighttime sounds of nature.

This was really a unique experience. We went as a family of 5 and left before sunset (6:30-8:30), paddled through a channel of mangroves until we reached the lagoon, where once we reached it, it was dark. They give you a few minutes to ‘free time’ paddle around before you group together for a little classroom session on the algae and ecosystem. We were there at full moon, which isn’t ideal to see the bioluminescence, but we were still able to see it and it was fascinating! The trip back is challenging because you return though the channel against the current, but the guides help you. I would definitely recommend!

We enjoyed the activity. The guides were very kind, entertaining and safety conscious. Kayaking was fun but a little chaotic, mainly because a lot of other groups were going in the opposite direction when we started the tour. It definitely helped to be in good shape and having kayaked before, but not totally necessary. The bioluminescence was pretty visible and overall it was a great experience!

What a great time! We were sent great information before the trip, the guides were very friendly and helpful, and they took great pix! It was good having four guides for 16 kayaks — while not a lot of instruction was given, they were there for help and advice when needed. They gave great information about the area and the bioflagellates. And because we had a «super moon» that night (so not great visibility for the bioluminescence), they had a huge tarp they spread over 4 kayaks at a time so we could splash and see the blue sparks! And having the super moon for a moonlight trip was excellent. Great experience!

Excellent Experience

This group goes the extra mile to introduce guests to Laguna Grande and the bioluminescent experience, and keep you extra safe.
I highly recommend this group if you’re a beginner kayaker and are interested in experiencing the bio bay. I also recommend going during a New Moon.

The tour is incredible!

The bay is so beautiful in the dark, and kayaking there through the mangrove channel is unforgettable. These guys are very professional, focused on safety, helpful and nice. They are very knowledgable about wildlife and about bioluminescence of the laguna. Highly recommend Puerto Rico Bio Bay Tours!

Very thorough tour!

As inexperienced kayakers, we felt confident getting into the water, that if anything were to go wrong, it would easily be fixed! It was a clear night, we saw so many stars, and although we visited at a time when the glow wasn’t as bright as it can be, we still got to see some definite glow!
