The island is 9 km (5.6 mi) and 2.5 km (1.6 mi) wide, with a maximum height of 338 m (1,109 ft) and a total area of 26 km2 (10 sq mi). Gorgona is separated from the continent by a 270 m (890 ft) deep underwater depression.
Administratively the island is part of the Municipality of Guapí in the Department of Cauca. Gorgona functioned as a prison from 1959 until 1984 when it was turned into a National Natural Park. The island, noted for a large number of endemic species and unique ecosystems, was established as Gorgona Island National Park in 1985, in order to preserve its richly varied wildlife of the sub-tropical forest and the coral reefs offshore
