Dientes de Navarino

Dientes de Navarino Circuit

A remote 53km loop across rugged passes, glacial tarns, and jagged peaks on Isla Navarino, Chile—often called the world’s southernmost trek. Wild, isolated, and a true test of preparation.

• Distance: 53km (loop)
• Duration: 4–5 days
• Category: Backpacking Circuit
• Difficulty: Hard

Overview

The route circles the serrated “teeth” of the Dientes range. Expect steep passes, beaver-dammed valleys, and constant views toward the Beagle Channel and Cape Horn. Navigation and self-sufficiency are essential.

History and Cultural Context

The Yahgan people lived seasonally in this subantarctic region, moving by canoe and foot. European settlers introduced beavers in the 1940s, now a dominant ecological factor. The trek today symbolizes wilderness at the edge of human presence.

Seasonal Highlights

Summer offers long daylight but still unpredictable storms; snow may linger on passes into January. Early March brings calm weather, crisp nights, and golden lenga beech forests. Winter conditions make the trek unsafe for most hikers.
