Bioluminescent kayaking in Puerto Rico was truly magical! Paddling through the calm waters at night, every stroke of the paddle lit up the water with a blue-green glow. It felt like the stars had fallen into the lagoon. The guides were friendly, knowledgeable, and made us feel safe the entire time.
Such a great experience. The guides were extremely helpful and very knowledgable. This excursion gives you the opportunity to see the island from a different perspective and you kayak underneath the interwoven branches of the mangrove trees route to Laguna Grande.
We had a wonderful evening kayaking to the bioluminescence bay at the Laguna Grande Nature Reserve in Fajardo. The tour guides are very professional and helped keep our group together through the mangroves. The bio bay was beautiful and peaceful. It was a night we will never forget.
This was one of the highlights of our trip! Guides were amazing and the bio bay was so cool. I would recommend going on the earlier trip - that way you get used to paddling when it's still light out and get to experience the channel both ways (in the light and in the dark)... would 100% recommend.
Had a great time on the bio bay kayak tour. This was a once in a lifetime experience. Went with my best friend and we would recommend! Brian was a great guide, Ineliz helped us throughout the route and the whole crew made sure we were taken care of throughout the experience.
Lori, Miguel, Brian and Daniel were wonderful guides. We saw lots of illuminating plankton even with a low glow advisory. The Biobay tour is a must when visiting PR. The communication prior to and throughout the was top notch.
Our tour guides, Miguel, Daniel and Francisco were amazing. They taught us about some history and science about the bay as we kayaked and were quick to help us out if we were struggling. Would highly reccommend!
