9 hours (approx.)
You should have high cardiovascular fitness and experience on full-day mountain hikes; ability to handle sustained ascents and uneven terrain required.
Scale a Fuegian glacier in one long, demanding day. The Ojo del Albino Glacier Challenge pairs a forested approach to Esmeralda Lagoon with a rocky climb to a blue-tinged glacier, all guided from Ushuaia.
A low sun slices through lenga trunks as the van drops you at the trailhead and the silence of the Fuegian forest tightens around the group. The first hour moves easily—soft earth, moss, and the steady chatter of a guide who knows where the wind hides good views. The walk opens onto Esmeralda Lagoon like a held breath being released: green water rimmed with lichen-streaked boulders, then a climb that demands attention and calves.

Weather changes fast—bring a waterproof breathable shell and an insulating mid-layer to handle wind, drizzle, or sun.
Guides provide crampons; arrive comfortable with basic steps and locking mechanisms or ask for a brief tutorial at the trailhead.
Choose sturdy, waterproof hiking boots with good ankle support—trail crosses peat and scree where a twisted ankle ends the day.
Carry 1.5–2 L of water and high-energy snacks—cold reduces thirst, but effort at elevation increases calorie needs.
The trails trace routes used by indigenous Yamana and later by settlers who established Ushuaia as a port and penal colony; the landscape reflects glacial sculpting over the last Ice Age.
This is fragile sub-Antarctic terrain—stick to established routes, avoid trampling peat bogs, and pack out all waste to limit erosion and habitat damage.
Protects against wind-driven rain and keeps layers dry during the exposed glacier approach.
Necessary for peat, rooty forest trails, and loose moraine near the glacier.
Retains heat during breaks and after exertion in cold high-elevation air.
Carry hydration, spare layers, sunscreen, and your camera securely.
