Returned here for the first time in about 15 years. Not as great as I recall from before. The illumination was not nearly as bright as I remembered and you're no longer permitted to swim in the bay (for good reason). It's still a very...More

We joined the night tour with Yokahu Kayak Trips. It was an amazing experience! The luminescence light glowed brightly when we moved our hands in the water. To enhance the experience, the operators brought a black plastic sheet to cover the group so that we...More

To be honest the Bioluminescent plankton were pretty underwhelming. It was nothing like in the photos. Still pretty cool though. The really fun part for me was paddling through the mangrove trees in the dark and the amazing night sky. Great family outing. We went...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...More

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...More
