This is an absolute must do when on Vieques. We went with a small tour group that had clear bottom kayaks. I strongly recommend the clear kayaks.

Seriously it is so rare to have such an amazing opportunity as to go to a bioluminescent bay in the warm weather looking at a sky so dark you can see the Milky Way. Honestly one of the best things I've ever done. It's well...More

You must see it to believe it! Be sure to go during new moon. Overcast sky is best. Our tour on the bay was 40-45 min.

Words cannot describe the magic of the bio bay. You just have to experience it. Don't forget to trail behind the herd a little and watch for fish swimming - they cause the dinoflagellates to glow, too!

Absolutely worth doing. We did this on a clear night with almost no moon and not only was the bay incredible, but so were the stars. Lots of schools of bait fish darting around with their own glow, easy to paddle around, and warm water...More

Everyone loved this, but the terrible girl at my first hotel, who booked it for me, never mentioned Kayaks, getting wet, wearing a bathing suit, and leaving all my valuables in a van, while we walked barefoot in the dark, to the water. All of...More

Well the tour usually starts at 7 or 9 pm. Tour usually lasts for 2 hrs. The latest airplane or ferry leave the island at 8pm. That leaves you no choice but to stay overnight on the island. Black beard sport is pretty good.
