It is an uninhabited island off the southern coast of Puerto Rico, in the municipality of Ponce. The island is protected by the Reserva Natural Caja de Muertos natural reserve, because of its native turtle traffic. The island measures 2.75 km long northeast-southwest, and up to 860 meters. It has an area of 1.54 km². Close by are Morrillito Key and Berbería Key both part of the Caja de Muertos Natural Reserve. Berbería Key belongs to Rio Canas Abajo barrio of Juana Diaz municipality. In fact, one of the beaches on the island, Pelican Beach, has been designated as a Blue Flag Beach, which means that the ocean water quality is monitored, there are facilities (composting toilets) and paramedics/guards watching the beach. The island also boasts hiking trails that lead to an old lighthouse, a cave, and a longer trail that goes to the other end of the island. There are some reefs off the north-eastern side of the island, but you need a boat to get to them. There are other beaches on the east side of the island, but they are roped off during turtle-nesting season. Besides, it looks like it may be too rough to swim on the east side due to sea conditions. There is a great map of the island, and some informational signs placed throughout the park explaining the island, its history, and some of the flora that you will see.
