Must do

Beautiful. Emily was a great guide. Easy to do for any skill level. I didn’t like there were other tour groups on water at the same time that were too loud and being disrespectful to peace of the tour. Not our tours fault.
Worthwhile experience

Great experience! We went at 5:30pm and I was worried that it wouldn't be dark enough to see the bioluminescence (sunset was 5:45pm), but with the tarp it wasn't a problem. It was actually nice to kayak through the narrow channel before it was fully dark so people could get used to it. Though traveling back was more challenging, especially since there were many other kayaks going out while we were coming back. The bioluminescence itself was actually cooler than I thought it would be. Definitely worth seeing! Just keep your expectations realistic.
Must to do in 🇵🇷

What a fabulous day!! It was fun experience bioluminescent, tour operators and his team are very friendly. Even if you not si good in kayaking or going wrong, they are very helpful and friendly. I went with my son and we both had good time with ride and bio. Everyone who visit 🇵🇷 must do this tour.

Beautiful evening snd best way to celebrate our 1 yr Wedding Anniversary. Never seen the water light up the way it did. Best Ive seen in the 20 years I've been.
Must do!

Such a cool experience! The moon was too bright to see the bioluminescence but the tours had a back up plan which still made the experience amazing!
Nothing like the pictures.

Kayaking through the canal was fun, but there was nothing bioluminescent about the bay. We went on a night with no mom and few clouds, but the guides blamed it on light pollution. It was an expensive trip for a rather ordinary kayak experience. There were so many groups on the lagoon that it felt like urban kayaking.
Truly a one of a kind experience with wonderful guides

Our beloved captains Rafael, Ashley, Emely, Ahmed, AJ, & Carlos were super friendly, funny, helpful, and environmentally informative as they provided us an incredible night kayaking experience in a GORGEOUS bay/canal/wildlife reserve. Super convenient location in the Kayak Village with nice shoos & the guides had a super swift and easy check-in /safety brief set up. The stars in the bay were the most magical thing (especially the shooting star we saw!!!) and the bioluminescent ~dinoflagellates~ were arguable the most amazing thing I’ve ever seen/the 8th wonder of the world. LONG LIVE THE RED MANGROVE TREES!!!
We had a blast
