About this experience
Embark on a mesmerizing adventure with our Bio Bay tours, where you'll glide through the bioluminescent waters of Mosquito Bay and witness the breathtaking glow created by tiny organisms called dinoflagellates. These microorganisms emit light when disturbed, creating a magical display as each paddle stroke ignites trails of sparkling blue.
Travel Notice: If returning to Puerto Rico on the late ferry, book our 7:00 PM tour Monday- Sunday. Coordinate transportation in advance.
Ferry Ticket Recommendation
Secure your ferry tickets when you book your tour. For the best chance of a seat, purchase in person at the Ceiba ferry terminal. Our tours require a minimum number of participants and may be rebooked or canceled if that number isn’t met. Travel light and bring only essentials. By arranging both your tour and ferry tickets early, you can relax and enjoy your adventure worry-free!
