Experience Puerto Rico’s Bioluminescent Bay

Your visit to Puerto Rico isn’t complete until you discover the natural wonders of one of our bioluminescent bays. Join us on an unforgettable tour to see this unique phenomenon.

Las Cabezas de San Juan National Park, set aside by the Department for Natural and Environmental Resources, is recognized as a world-class treasure. Within it is found one of the world’s few ‘Bio Bays’ where there are sufficient microscopic bioluminescent organisms to produce light visible to plain eyesight. Just agitate the water to activate the show.

We start our journey with a pickup at your hotel lobby. It’s an hour and a half drive from San Juan to Fajardo. The highway east drives you past the mountains that are the tropical rainforest. Immerse yourself in the perspective of the north east side of Puerto Rico. Once in Fajardo, you will receive a briefing on the use of tandem kayaks, with additional rules to follow on entering the bio bay.

After dusk, our tour guide will lead you and paddle out towards a mangrove lined canal that connects to the bio bay. Scientific reasons for the effect will be provided. Once at Laguna Grande an amount of time is given to frolic about kayaking and splashing water. (approx. 30 min.)

Guide, life vests, and Kayaks are provided. We drop you off at your hotel around 11 p.m.
