With a name that comes from its coffinlike shape, Caja de Muertos is a few miles off the coast and has the best beaches in the Ponce area. It is the second-best spot in southern Puerto Rico for snorkeling, after La Parguera. Due to the hawksbill turtles that nest between May and December, the island is protected by the Reserva Natural Caja de Muertos, but you can still swim, snorkel, and dive. A 30-minute hike across the island will take you to a small lighthouse that
dates back to 1887. There are bathrooms and picnic tables for day use but not much else. Ask one of the many boatmen at La Guancha to take you out for about $30 round-trip. Scheduled boats costing $25 round-trip leave La Guancha Friday through Sunday at 8:30 am, returning around 3:30 pm. During summer, the boat trips depart daily.
Boats leave from La Guancha, at the end of Rte. 14, Ponce, Puerto Rico
