The experience begins at our meeting point where guests check in, meet their guide, and receive a brief safety orientation and overview of the tour. Once everyone is ready, guests board our transportation for a short scenic drive to Mosquito Bay. The drive takes about 10 minutes and travels along rustic terrain, offering beautiful views of Vieques at night with minimal light pollution and early glimpses of the star-filled sky.
Upon arrival at the bay, guests enter the water by kayak and begin the guided bioluminescent tour. You will spend approximately 55 minutes kayaking on the water, where every paddle stroke lights up the bay with glowing bioluminescence. Guides share information about the ecosystem, the microorganisms that create the glow, and the natural history of Mosquito Bay while allowing plenty of time to enjoy the magical surroundings. After the kayaking portion, guests return to shore and are transported back to the meeting point, completing the experience.

It was a really cool to see the glowing water. Getting to the kayak launch was rough. It will beat you up before you get there, really really rough ride down a dirt road thats never been maintained. Nonstop holes that swallow 1/2 the bus. Then walk through poop mud barefoot. If your paddling with a kid who cant paddle be physically fit to keep up. Everyone has 2 paddlers in a yak so they move fast. Ive never seen anything like the glowing before so it was really neat but a workout to get there. The guide was great and patient!

Don’t miss this on your trip to the island! You will probably have to stay the night on the island if your main accommodations aren’t already here but, it will be worth it! GO ON THE DARKEST, DAY OF YOUR TRIP!!! this will make the experience that much better; if it is a full moon the bay will not be as bight as say a new moon! The tour guides were very kind and took their time explaining everything and keeping pace with the slower kayakers. I promise you won’t regret this experience!

Trip advisor misled and put this on things to do in PR. Not telling the customer you had to fly there. We lost our money as it was a last minute booking.

This trip was worth it! It’s easy to find the meeting point where you will get on a bus to drive over a rutted, washed out road. The bay is quiet and warm and good for beginner kayakers. There are 2 in each boats. We had the bay to ourselves it seemed on the 8:15 tour. We had a star studded sky and every touch of the water glowed with diamond like light . The clear kayaks are a must. Carlos was our guide and he was both knowledgeable and supportive to boaters. He had fun bringing out jumping fish with his light.

Transportation was all screwed up because of the parade but got on an earlier tour anyways. Cool experience not sure I’d do it again but will recommend to friends and family.

The trip was canceled because of the full moon making it too bright to see the bio luminescent at night.

I wish I had a positive thing to say as most people do. The problem was there was a full moon last night when we went so we couldn’t see ANY bioluminescence. I understand this is out of anyone’s control. What is in people’s control is taking people on a tour once a month during a full moon, knowing full well nothing will be seen. If the company knows they can’t see anything, then they should not offer the tour at full price. The people were nice. I just feel it’s dishonest to take our money knowing nothing will be seen.

This tour is a scam unless you go at the right time/lunar cycle. We had read that the bioluminescence would be fainter if the moon was too bright…so I’m taking full blame for that; but there was zero bioluminescence. Please be aware and don’t waste your money unless you know it’s the right moonlight. This was a costly mistake and if my review can save one person $, it’ll be worth it. Company of course offered no warnings up front and was happy to take our money knowing full well there was nothing to see.
