The Chilean Navy maintains a station on the island, consisting of a residence, utility building, chapel, and lighthouse.[1] A short distance from the main station is a memorial, including a large sculpture featuring the silhouette of an albatross, in honour of the sailors who died while attempting to "round the Horn".[2]

The island is within the Cabo de Hornos National Park.

The world's southernmost tree, a Nothofagus betuloides, is found on Hornos Island.[3]


The composition of the island is mainly of Cretaceous granite with Jurassic volcanic rocks in the northwest. The lower areas of the island are filled with peat moss.
