Isla del Frío is a small uninhabited island off the southern coast of Puerto Rico.[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 980feet 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. The island has an area of 2.89 cuerdas[8] (one cuerda equals 0.97 acres[9]). It is located at latitude 17.96444° and longitude -66.55639°.[10]
The island is a small 6-foot flat-topped island and consists mostly of brush.[11] The climate is dry and the island supports dry forest.
Though not officially a nature reserve, the island is administered by the Puerto Rico Department of Natural and Environmental Resources.
