Coffin Island

Caja de Muertos is an uninhabited island off the southern coast of Puerto Rico, in the municipality of Ponce. The island and its surrounding waters are protected by the Caja de Muertos Nature Reserve, because of its native turtle traffic and ecological value of its dry forests and reefs. Hikers and beachgoers are often seen in the island, which can be reached by ferry from the La Guancha Boardwalk sector of Ponce Playa. Together with Cardona, Ratones, Morrillito, Isla del Frio, Gatas, and Isla de Jueyes, Caja de Muertos is one of seven islands ascribed to the municipality of Ponce.
