Select participants and date
The minibus leaves Ushuaia as a grey skiff of houses recedes and the road climbs into lenga and coihue forest. Damp peat smells of moss and iron; the trail ahead threads through boardwalks and bog-strewn clearings. After a steady climb the trees peel back and Laguna Esmeralda appears like an improbable pool of jade pressed into the Fuegian cordillera. Wind scratches the surface, pushing flakes of light across the water as the guide sets out the lunch box and the group takes stock of the view.

Adventure Tips
Bring waterproof boots
Trails include peat bogs and wet boardwalks; ankle-supporting, waterproof hiking boots reduce slipping and cold feet.
Dress in layers
Wind and rain can appear quickly; pack a breathable insulating layer and a waterproof shell.
Carry at least 1 liter of water
Water is not available on the trail and exertion in cold wind still dehydrates—bring an insulated bottle to avoid freezing.
Watch for beaver ponds
Beaver activity alters the path and creates soft ground; follow the guide’s route and avoid walking on fresh dams.

Conservation
Beavers, introduced decades ago, have dramatically altered local waterways; stay on trails and avoid disturbing riparian zones to limit further impact.
