Chile
Isla Navarino
Teeth of rock trail across the world's southernmost trek above the Beagle Channel.
Teeth of rock jut from the ridgeline like a broken jaw, wind hammering your face as the Beagle Channel glints far below. The trail markers disappear somewhere above the treeline. Up here, south of Puerto Williams — the world's southernmost city — you navigate by cairn and instinct through sub-Antarctic tundra where no refugio exists.
Isla Navarino lies south of Tierra del Fuego in Chile's Magallanes Region, separated from Argentina by the Beagle Channel. The Dientes de Navarino circuit is rated among the 10 hardest multi-day treks in South America — no maintained trail, no shelters, mandatory route-finding in conditions that shift from clear to whiteout within the hour. The Yaghan people lived on this island for 8,000 years, surviving sub-Antarctic cold without permanent fires, using only animal grease as insulation. In autumn, the lenga beech forest turns copper-red across the entire island, visible from the ferry crossing. Puerto Williams itself holds a rawness that Ushuaia across the channel has long since polished away — a handful of harbourside eateries, a navy base, and the knowledge that Antarctica is the next stop south.
Solo
This is the trek for the solo hiker who has done everything else and needs a route that still feels genuinely wild. No crowds, no infrastructure, no safety net — just you and the teeth of rock at the bottom of the world.
Friends
A small, experienced group is the safest way to tackle the Dientes circuit. Shared navigation, shared wind-battered camps, and king crab in Puerto Williams afterwards make this a trip that defines friendships.
