If you want to use a tour guide, your most reliable is the group that runs the electric pontoon boat. It's called Mosquito Bay for a reason...be prepared to be popular with a lot of mosquitos near the shore. They ease off when you get out into the bay. Do NOT wear insect repellent. It kills the glowing organisms. You... more

Yes you have to drive out in a van packed with people and you have to walk through some nasty mud, but this trip is UNBELIEVABLE ! We had a single guide and he was courteous, funny, and responsible. Going out in that bay in a moonless night is an experience you just can't get anywhere else. Jumping this water... more

The bioluminescent bay is located in the mosquito bay in Vieques and has the highest concentration of dynoflagellates in the world. Vieques is a beautiful island located to the East of Puerto Rico.

If you would like to learn about everything from the stars to the water to of course the organisms in the water, this is the... more

Yep, just as everyone says: The bioluminescent bay is an unforgettable experience! You can find tour companies/organizations to the bay right on the main street along the water front in Esperanza (Vieque's 2nd town after Isabela 2, located in the southern coast and my favorite of the two) . The tour will take you in a mini van or mini... more

We made reservations with Abes (after 3 emails and 3 phone calls, finally got a return call and email the day before the tour. We were at the appointed place 10 minutes early and waited 15 minutes past the pick up time and then made our way to the next pick up location with no luck. Late had a message... more

First of all, I would suggest looking around at the choices you have. We went with Eco Action Adventures, and there uncoordinated call backs and unorganized approach should have been an indicator.
