About Cape Horn Biosphere Reserve

The Cape Horn Biosphere Reserve is a remote and ecologically rich area located at the southernmost tip of South America, renowned for its pristine wilderness, exceptional biodiversity, and unique maritime sub-Antarctic ecosystems.

Wilderness Landscape & Natural Heritage

The Cape Horn Biosphere Reserve encompasses the rugged archipelago surrounding Cape Horn, located within Chile's Magallanes and Chilean Antarctica Region. Established as a UNESCO Biosphere Reserve in 2005, this reserve covers both land and marine environments totaling over 4,000 square kilometers. The region features dramatic cliffs, steep mountains, dense native forests, peat bogs, fjords, and pristine waterways, all shaped by harsh weather and powerful oceanic currents. The reserve’s isolated position makes it an ecological sanctuary, home to endemic species like the southern river otter and the Magellanic woodpecker, as well as numerous migratory birds such as albatrosses and petrels. The marine environment supports whales, dolphins, and sea lions. Historically, Cape Horn was a key maritime passage prior to the Panama Canal, embedding rich seafaring heritage and exploration history in the landscape. Visitors to the Cape Horn Biosphere Reserve can engage in specialized eco-tourism activities including hiking through undisturbed native forests, bird watching of rare seabirds, sea kayaking along fjords, and cultural tours exploring the maritime history. Its remote location offers a profound wilderness experience, with opportunities to witness one of the last great wild frontiers. Safety and environmental mindfulness are critical due to the region’s extreme weather conditions and fragile ecosystems. The biosphere designation supports conservation, scientific research, and sustainable local community development in harmony with the natural environment.
