[1] Together with Caja de Muertos, Gatas, Morrillito, Ratones, Cardona, and Isla de Jueyes, Isla del Frío is one of seven islands ascribed to the municipality of Ponce.

[2][3][4] Like Isla de Jueyes, the island is considered part of barrio Vayas.

[5] The island, sometimes erroneously considered a key (or, cay), and sometimes erroneously spelled Isla del Erio,[6] is located approximately 980 feet (300 m) south of the mainland Puerto Rican shore at the mouth of Rio Inabon.

[7] The closest populated point on the mainland is Hacienda Villa Esperanza, located in barrio Vayas; however the closest geographic point on the mainland is barrio Capitanejo in Ponce.

Though not officially a nature reserve, the island is administered by the Puerto Rico Department of Natural and Environmental Resources.
