Las Cabezas de San Juan Nature Reserve is one of the most unique reserves in Puerto Rico. Of the seven ecosystems in Puerto Rico, six are represented here. Tours are given from Wednesday through Sunday by reservation only. You will learn a lot about the area and can enjoy the spectacular views from its observation deck. From there, you can see the Bioluminescent Lagoon, Icacos, and other spectacular views of the Atlantic Ocean. And off in the distance the mountains of El Yunque will call you away from our beautiful seaside village.
