It is located on the northeast tip of the Island and its name arises from the shape of the three rocky headlands that extend to the Atlantic Ocean. Its land was acquired by the Puerto Rico Conservation Trust in 1975 and was designated as a Nature Reserve in 1986.
A bioluminescent lagoon, mangroves, coral reefs, dry forests, sandy and rocky beaches set between headlands—visit all these ecosystems in one place, the Cabezas de San Juan Nature Reserve, in Fajardo. You’ll find one of our most frequented visitor centers here, and it’s only a step away from the best resorts in the area. You can take traditional, night and thematic tours from here—on bike, kayak or trolley—always in the company of a environmental interpreter who will show you everything about the ecosystems, landscapes, and wildlife of the reserve, including the breathtaking view of the northeast tip of Puerto Rico form the top of the Fajardo Lighthouse. There are many ways to participate for nature in Cabezas de San Juan. They also offer workshops and special events, as well as volunteer and Citizen Science opportunities year-round. Cabezas de San Juan is currently closed due to renovations of impacts to the lighthouse caused by hurricanes Irma and María.
Voluntary workshops are open free of charge upon reservation 787.722.5882, wwww.paralanaturaleza.org
