Vieques Traveler - Being on the boat gives a vantage point above the water. We were able to see schools offish glowing as they swam through the water. Captain answered all of our questions and was well versed in the history and ecology of the bio bay. Only downside….road in and out is very, very rough.

Must-do on Vieques - A once-in-a lifetime experience. You see the stars and Milky Way above and the magical lights in the water. The catamaran offers a fabulous expansive view of the fish triggering the bioluminescence and you’re still able to stir the water with a pole to trigger the light yourself. It’s also easy to hear the guides and ask questions. They were extremely knowledgeable. If it rained that day, be prepared for mud and puddles walking to the launch from the shuttle van.

Interesting tour,... - Interesting tour, excellent and knowledgeable guide, responsive to questions. Organisms looked white unlike photos that make them appear blue.

Very prompt for pickup... - Very prompt for pickup and drop off. The driver and guide were very friendly with the guide providing a lot of information on the bioluminescent bay and the starts. The boat was not a catamaran as noted in the description. While the bio bay was cool it was only visible when we put sticks in the water. Overall it was a nice trip but more about the constellations and stars. Not sure it was worth the high price though.

Bioluminescent and the stars - Great experience despite the unbelievably bad access road and the sudden $3 per person add-on at the end

Disappointing Experience - During the new moon, we went on the 40 minute boat tour to see a long-awaited phenomenon - a bioluminescent bay. While our guide was quite knowledgeable, and the night sky was extraordinary, the experience was a disappointment because of the multitudes of kayakers on tours that overwhelmed the phenomenon. For all the cost and effort that went into the Vieques visit, it wasn't worth it. I'd recommend going elsewhere where you might have a better chance to actually see this natural wonder.

Be Careful. - This was supposed to be a relaxing experience. My husband fell getting when the ramp fell into the water while he was walking towards the boat and hurt his back and leg. Operator was reached and never responded to our request for refund to cover part of my husband's medical expenses.
