In Colombia’s Darién, the forest does not stop at the map’s national border. Wetlands beside the Atrato River meet humid lowland forest and rising ground on the Serranía del Darién, forming the landscape protected by Los Katíos National Natural Park. It is a place of exceptional biological importance, but not an ordinary park itinerary: on 6 October 2026, Colombia’s National Natural Parks authority lists it as closed and says ecotourism is not offered. There are no current public opening hours or visitor tickets to recommend.
Los Katíos lies in north-western Colombia, across parts of Chocó and Antioquia, near the frontier with Panama. The Colombian authority gives the park’s area as 77,968.26 hectares; UNESCO’s World Heritage description uses 72,000 hectares for the property inscribed on its list. Those figures refer to different institutional descriptions and should not be casually blended. The park was declared in 1973, its boundaries were expanded in 1979, and UNESCO inscribed it in 1994.
