Gorgona Island Prison Ruins – Guapi, Colombia - Atlas Obscura

Gorgona Island Prison Ruins

This tropical island hosted a maximum-security prison until it was abandoned to make way for a national park. 


Sometimes called the “Alcatraz of Latin America,” Gorgona Island is home to an abandoned prison now completely overrun by the Pacific island’s unique flora and fauna.

Originally named San Felipe, the island was later renamed after the “gorgons,” Greek mythological creatures whose hair was made of snakes, due to the high number of venomous snake bites suffered during the Spanish colonial era.

In 1959, after Colombia made it illegal for private individuals to own islands in the country, a maximum-security prison was built on Gorgona Island to house some of the nation’s most dangerous criminals. The prisoners on Gorgona Island were stripped from their identities and instead were assigned numbers. The harsh living conditions made the prison infamous, coupled with the fact that the island’s shark-infested waters and poisonous snakes made it very difficult for inmates to escape. Throughout the history of the Gorgona prison, there were a total of 25 escape attempts, only three of which were successful. 

After a little over two decades in operation, the Gorgona prison was eventually closed down in 1984, and the entirety of the island and its surrounding waters were turned into a national park the following year. Today the landscape is a protected wildlife habitat home to many rare species that live among the ruins of the abandoned maximum-security prison.

Much like the Galapagos Island, Gorgona is home to a unique ecosystem influenced by thousands of years of separation from the mainland. The island is the sole habitat of the blue anole (Anolis gorgonae), the only all-blue lizard in the world. It’s also home to the brown-throated sloth, the capuchin monkey, and a large population of venomous snakes. The island is a popular spot for scuba diving since it’s not uncommon to spot whale sharks, hammerheads, white tip reef sharks, and moray eels. Whale-watching is possible annually, between June and October, as the island is a prime breeding and calving location for humpback whales. 

Today, a navy station on Gorgona is responsible for preserving the integrity of the island’s ecosystem, maintaining the old prison ruins, and supervising the safety of the visitors. Local guides are available year-round and strict regulations, like curfews and wearing gumboots, are enforced to help preserve the local ecosystem and prevent visitors from getting bit by the slithery inhabitants of the island.
