The first steps out of the van feel like an admission ticket to a wilder Argentina. Air here carries a clean, metallic edge; wind sketches patterns across low lenga trees and the trail immediately begins to climb, gravel crunching underfoot. After a few kilometers the forest opens and the lagoon appears—green as its name suggests, daring you to pause and take it in. On this private-route trek, a small mountain refuge perches on the shore with a salamander stove burning, promising a hot, gourmet lunch when you arrive.

Layer for wind and wet
Temperatures can drop quickly and wind is persistent—pack a waterproof shell and insulating midlayer you can add or remove on the trail.
Use good traction
Boggy sections and late-season snow make microspikes or crampons useful; the operator supplies crampons but bring footwear that accepts them.
Eat and hydrate before the descent
The refuge lunch is filling; top up water and snacks at the shelter so you leave energized for the return walk.
Confirm pickup time
Hotel pickup is included but times are specific—double-check the pickup window the evening before to avoid delays.
Waterproof breathable shell
Blocks wind and rain during exposed sections and at the refuge.
Sturdy waterproof hiking boots
Protects ankles and keeps feet dry across boggy terrain and rocky approaches.
Insulating midlayer (fleece or down)
Keeps you warm at the lakeshore while you eat and rest.
Microspikes or crampons
Useful for late-season snow and icy sections; operator may provide crampons when required.
