The bay illuminated as they said it would.. looks like underwater fireflies, but it was a full moon so it was hard to see. I would recommend that you check the lunar calendar to ensure you get the most out of your Bio Bay trip.

Go see the biobay. Having gone in 2008 and 2016 I feared the bay would not glow as bright after Maria. Not true. The bay was the brightest I can remember and apparently has made a full recovery. Loved the tour by JAK Sports.

While it wasn't as spectacular as before the hurricanes it was magical nonetheless and we don't regret going to see it. Choose a smaller outfit so you get more time on the water to learn more. You need to know the organisms got washed out...More
