Don't miss this unique opportunity for a memorable and relaxing trip into the enchanting bio-luminescent bay at Laguna Grande of Fajardo.

Under the blanket of the night sky and, in the company of the historic lighthouse of Fajardo, you'll kayak through the calm water, literally making it glow as you paddle. The bay is filled with bio-luminescent organisms that light up in a manner similar to glow worms or fireflies when physically agitated. While the organisms themselves are tiny, when a large number of them light up simultaneously, the effect is like a miniature Milky Way sweeping through the water -- truly a beautiful phenomenon.

Enjoy refreshments upon your return to shore.
