Mosquito Bay in Vieques is recognized as the world’s brightest bioluminescent bay and is one of Puerto Rico’s most extraordinary natural wonders.
The glow is created by microscopic organisms called dinoflagellates. When the water is disturbed by a paddle, kayak, or movement in the bay, these organisms emit flashes of blue green light that illuminate the water around you.
Bioluminescence is a natural phenomenon, so its intensity can vary depending on moonlight, weather, water conditions, and other environmental factors. The glow may also appear different to the human eye than it does in photography.

WHAT OUR GUESTS SAY
The staff was very friendly. The experience was enjoyable for the whole family. They worked with the children on board to help teach them about sailing and snorkeling.
We have done many snorkeling tour in various places, this tour tops our list. Most “sailing” tours only go to the snorkeling site with the engine running. This tour sailed to and from the beach. We snorkeled at two places and had a two-hour stay on a great beach. Lunch was great and we had plenty to enjoy.
I highly recommend Fun Cat Catamaran if you are in Puerto Rico.
We have had a great trip to Puerto Rico and by far, the best thing we’ve done is spent a day on the Fun Cat Catamaran with Capt. Jim and his crew. They were all outstanding!!! The ship was beautiful. The equipment was top notch. The lunch buffet, snacks, and drinks were all delicious. The Pina Coladas were awesome!!! And all of the places we stopped were amazing. Do this tour – you will not be sorry!!!
