Navarino Island Island
Remote southern Chile island near Cape Horn, rugged terrain
Navarino Island (Isla Navarino) in Chile sits near Cape Horn and Puerto Williams; trekkers tackle the Dientes de Navarino circuit, and visitors come for raw subantarctic scenery and remote hiking.
Navarino Island (Isla Navarino) lies at the southern tip of Chile’s Tierra del Fuego archipelago and is part of the Region of Magallanes. It is one of the southernmost inhabited islands and is notable for its rugged, largely roadless terrain and subantarctic ecosystems.
The island contains the town of Puerto Williams, which serves as the main population and service center and as a naval base. Outdoor visitors come for the multi-day Dientes de Navarino trek, sea kayaking, birdwatching, and to use the island as a staging point for voyages to Cape Horn and Antarctic routes.
Navarino’s landscape includes steep ridges, glacial valleys, peat bogs, and a coastline of fjords and channels. The climate is cool, windy, and often wet, which shapes the island’s vegetation and travel conditions.
Geographically the island sits south of Isla Grande de Tierra del Fuego, separated by channels of the Beagle Channel system, and lies within Chile’s far south, administered from Puerto Williams.
- Puerto Williams: Home to Puerto Williams, often described as the southernmost town in the world and a gateway for Antarctic voyages and local patrols.
- Outdoor access: The island is a base for trekking and sea excursions into the Beagle Channel and the surrounding subantarctic landscapes; weather is changeable and trails are remote.
