The trail opens like a map unfolded across southern Patagonia: peat bogs that suck at your boots, the crunch of lenga leaves underfoot, and the thin, metallic light of Tierra del Fuego sliding down from serrated ridgelines.

Adventure Tips
Wear waterproof hiking boots
Much of the trail crosses peat and wet ground; waterproof boots with good tread will keep your feet dry and stable.
Bring layers and wind protection
Weather in Tierra del Fuego shifts quickly—pack an insulating midlayer and a windproof shell even on sunny mornings.
Respect the peat and boardwalks
Stay on marked paths and boardwalks to avoid damaging fragile peatlands that take centuries to form.
Protect against sun and glare
Bring sunglasses and a polarizing filter for photos; reflected light off the lagoon and snow can be intense.

History
The valley landscape reflects human and ecological histories—fur-farming-era introductions of beavers changed hydrology, and ranching and exploration routes shaped the trail network used today.
Conservation
This area’s peatlands store carbon and are sensitive to trampling; staying on trails and following guide instructions helps protect fragile soils and water quality.
