Welcome to Monumento Natural Isla Barro Colorado
This lush island in the middle of Lago Gatún is the most intensively studied area in the neotropics. Formed by the damming of the Río Chagres and the creation of the lake, in 1923 Isla Barro Colorado became one of the first biological reserves in the New World. Home to 1316 recorded plant species, including 500 tree species, 381 bird species and 120 mammal species, the island also contains a 59km network of marked and protected trails. It is managed by the Smithsonian Tropical Research Institute (STRI), which administers a world-renowned research facility on the island.
Isla Barro Colorado is open to a limited number of visitors on guided tours only.
