Participants should have strong aerobic fitness and regular hiking experience; expect sustained climbs and uneven footing.
A demanding full-day trek from Ushuaia takes you through peat bogs, lenga forest, and rocky ascents to a 20-meter ice wall and the vivid Emerald Lagoon. Expect 20 km of varied terrain, technical sections, and big views.
A low, wind-driven cloud lifts off the black peat and reveals a slice of turquoise—the Emerald Lagoon—like a secret kept by the mountains. You stand on the edge of the Tierra Mayor Valley, boots sinking slightly into sphagnum moss, while the Andes rise sharp and raw to the north, their flanks streaked with snow and rust-red scree. The trail ahead climbs from damp forest into a landscape that seems to have been chiseled by ice: ribs of rock, scattered moraine, and finally the pale, vertical face of Albino’s Eye, a 20-meter ice wall that drinks the winter light.

Roll layers: a wicking base, insulated mid-layer, and waterproof shell—conditions can change in minutes at these latitudes.
Sturdy, waterproof hiking boots with ankle support are essential; guides provide crampons when icy conditions require them.
Bring 2–3 liters of water and high-calorie snacks—steady energy beats large meals on long ascents.
Stay on boardwalks and marked trail to protect peat bogs and tundra that recover very slowly from foot traffic.
The valley sits within the traditional lands of Yámana peoples; later European settlers and gold-seekers influenced Ushuaia’s development as a port city and gateway to the southern ice.
Peatlands here sequester carbon and are easily damaged—staying on boardwalks and avoiding off-trail travel helps preserve the fragile Fuegian ecosystem.
Support and waterproofing for peat, scree, and possible wet crossings.
Quick protection from wind, rain or snow and warmth during stops.
Used when glacier or lagoon surfaces are icy—guides may supply them.
