Caja de Muerto Island

“Caja de Muerto” Island (Coffin Island) is located in southern Puerto Rico off the coast of Ponce (only 8 miles away). This island is only 1/2 mile in width (at the widest part) and 1 1/2 miles in length. It offers many things such as a lighthouse, an old hidden pirate cave, a few hiking trails, and gorgeous beaches. The whole island is also a well-protected natural reserve. Many believe that it got its name because it resembles someone lying down as in a coffin when seen from a distance. Others believe its name derives from a legendary coffin found inside the island’s cave.

Old Lighthouse

The hiking trails on the island take you among other places to the old lighthouse, which has a wonderful platform for a perfect view of the island. This platform is located right on top of the Almeida Cave. You cannot go inside the lighthouse, but the trek to the platform is well worth the view.

Caja de Muerto The Legend and the Cave

The legend that surrounds this island has to do with a pirate named José Almeida. He once fell in love with a Basque lady when he visited Curaçao. He married her and took her to sea, where she, sadly, was killed. He buried her in the cave mentioned above and visited her each year to leave some of his new treasure with her. When her coffin was found many years later, the island became known as Coffin Island.

The Beaches

The beaches on this island are idyllic. Pelican Beach has the designation of a Blue Flag Beach. These beaches have particularly high standards and are concerned about hygiene, conservation, and amenities. They are guaranteed to be administered in a way that is safe and environmentally conscious.

Some of the beaches located on the eastern side of the island are blocked off from the public when giant turtles are nesting. These beaches are not ideal to swim at for the most part because of the rough seas.

Caja de Muerto

This island offers no fresh drinking water, so travelers are encouraged to bring their own water, food, and beach gear for their visit.
