About Caja de Muertos Nature Reserve

Caja de Muertos Nature Reserve is a protected island reserve off the southern coast of Puerto Rico known for its pristine beaches, vibrant coral reefs, and unique coastal ecosystems, offering excellent opportunities for hiking, snorkeling, and wildlife observation.

Wilderness Landscape & Natural Heritage

Caja de Muertos Nature Reserve is centered on Caja de Muertos Island, a small uninhabited island located approximately 8 miles south of Ponce, Puerto Rico. The island is part of a nature reserve established to protect its unique dry forest ecosystem, endangered sea turtles, and vibrant marine life in surrounding coral reefs. Roughly 170 acres in size, Caja de Muertos features a mix of sandy beaches, rocky cliffs, and dry coastal forest with endemic plant species. Its terrestrial environment supports various birds, including migrating species and native reptiles. Visitors are attracted to the reserve for its outdoor recreational activities such as hiking along trails to a lighthouse dating back to 1887, snorkeling in clear waters teeming with tropical fish, and beachcombing on its pristine white sand beaches. The surrounding coral reefs are protected as part of the marine reserve, making it a popular destination for underwater exploration. Historically, Caja de Muertos served as a navigational landmark and a refuge for pirates and fishermen. Today, it remains a quiet escape from urban life with limited visitor infrastructure, emphasizing conservation and responsible tourism. Access is only by boat from Ponce, maintaining its remote and pristine character. The reserve appeals to nature lovers, snorkelers, photographers, and those looking to experience Puerto Rico’s natural coastal heritage away from the crowds.
