Gorgona: Welcome to the Jungle
It hasn’t taken long for nature to regain complete control of Gorgona Island. From the 1950s to the 1980s, this landmass in the Pacific was a maximum security prison — Colombia’s Alcatraz — but the facility was closed and declared a natural national park in 1985; the jail buildings are now overgrown with dense vegetation, complete with monkeys swinging from vine to vine. Gorgona is one of those places where the natural environment is almost comically inhospitable to humans. Visitors who come ashore at Gorgona today are strictly supervised, limited to groups of 80 at a time, and forbidden from wandering too far away from the coastline, for fear of encountering deadly critters. Gorgona shelters a wealth of endemic plant and animal species in its rainforests, including the small (and endangered) blue lizard of Gorgona. Gorgona also has some of the finest sandy beaches in Colombia, backed by palm trees and a thick curtain of green, letting you know that the creepy-crawly jungle is never far away on this island.
