Isla Navarino’s landscapes are dominated by beech forests populated with lenga, ñirre, and coigüe species. Mosses, lichens, and ferns blanket the forest floor, creating primeval scenery rarely found elsewhere.

Long before modern explorers set foot on Isla Navarino, the island was home to the Yagán (or Yámana) people, one of the southernmost Indigenous communities in the world. Known for their extraordinary adaptation to harsh climates, the Yagán developed specialized navigation skills, unique dwellings, and intricate craftsmanship. Their knowledge of marine routes and survival techniques remains a cultural cornerstone of the island.
Today, the main population is concentrated in Puerto Williams, a small but culturally vibrant town with museums, research centers, and artisanal shops. Visitors can learn about the region’s past through local exhibits, archaeological findings, and cultural tours designed to preserve the Yagán legacy while educating travelers about sustainable tourism practices.

The Dientes de Navarino Trek, often described as one of the most remote multi-day treks in the world, is the crown jewel of Isla Navarino. Its name—meaning “Teeth of Navarino”—comes from the jagged mountain peaks shaped like teeth rising from the landscape.
