The guides were the best! They kept everything safe and gave us the best service, we were able to see the bio organisms even when it was a cooler season.

One of the best tours on our trip! Our guides, Kevin and Manolo, were awesome! They're super knowledgeable, very hilarious and they play off each other like twin brothers! We were a small group and they were attentive to all our needs. They made this experience that more enjoyable. They made sure that we saw what we were there to see and that is the plankton/organisms in the water. I would definitely take this tour again and will recommend to everyone!

We were picked up at our hotel and traveled about an hour to the beach. Members of the group ranged from about 9 to 70 years. After a brief explanation of the tour and a safety review, we boarded our kayaks and paddled through a mangrove forest into a fresh water lagoon. After sundown, we began to look into the water for flashes of light. Unfortunately, the luminescence was low due to the time of year and a full moon. Paddling back to the ocean through the narrow channel, with moonlight filtering through the mangrove canopy, was a great experience. The guides were experienced and helpful to anyone needing assistance.

Could someone please let me know where my pictures are on facebook? They were taken by our wonderful guides, but i do not remember the where they said they were posted.
I would recommend this tour, but check the moon calendar for the best times.

Wonderful trip. The guides Michael, Kevin were well organized and very helpful. the luminescence was cool like little shooting stars but the trip through the mangroves was really the very best part of the trip--- so fun to kayak through the canopy and into the open lagoon. very glad we did this.
driver Michael was excellent as well--- I felt like I got a great view of Puerto Rico.
