Itinerary and highlights
Travelers will meet us at our kisok in Fajardo to get ready for their Bio-Bay tour! You will receive a briefing on how to properly use kayaks with the oars!
We will start our tour from Bahia Fajardo where travelers will follow our guide through a mangrove channel to the Bioluminescent Bay.
Leaving the channel and entering the lagoon by itself is a breathtaking experience! A wide expanse of gentle, rippling water surrounded by mangrove forests greets the adventurer, the mountains of the El Yunque Rainforest tower in the distance – profound tranquility envelopes all who enter!
Take view of the Fajardo Lighthouse, built by the Spanish in the 19th century, and of course, the incredible natural phenomenon that we’re here for – the shimmering glow of bioluminescence as you dip your paddles and glide through the sparkling water – an amazingly unique experience only found in few places on earth!

- ✨ Bioluminescence & Natural Conditions Disclaimer
- The bioluminescent glow is a natural phenomenon and its intensity varies daily due to environmental conditions beyond our control. Factors such as rainfall, tides, moon phases and brightness, cloud cover, water temperature, seasonal changes, sargassum, water clarity, and other natural events may affect the visibility and brightness of the glow.
- While our tour is commonly known as a "Bio Bay Night Kayak Tour," the experience is designed to offer much more than the bioluminescence itself. Guests will enjoy a guided nighttime adventure featuring the peaceful atmosphere of the lagoon, the surrounding ecosystem, the night sky, and the unique experience of kayaking in Puerto Rico after dark.
- Because bioluminescence is a naturally occurring phenomenon, we cannot guarantee the intensity of the glow or that it will be visible during your visit. In certain conditions, our guides may provide tarps or other light-blocking materials to help guests better observe any available glow by reducing surrounding light pollution. However, the use of these materials does not guarantee visibility of the bioluminescence.
- By choosing to participate in the tour, guests acknowledge and accept that glow intensity may vary or be absent due to natural causes. If the tour operates as scheduled and guests choose to participate, refunds, credits, rescheduling, or compensation will not be provided due to low or absent bioluminescence visibility.
- We appreciate your understanding and look forward to sharing this beautiful natural environment and unforgettable nighttime adventure with you.
- Since we are not the only operators in this area, there may be more participants in the bay then the maximum number of participants we take per schedule.
