You step out of the minivan and the air feels narrower—cold and bright with a clarity that sharpens every ridge. The trailhead opens into a corridor of lenga and ñire, the forest floor spongy with peat and carpeted in pale moss. For the next two hours the path threads river braids and low bogs, climbs and falls around hummocks, and finally cracks the view: an intense, almost unreal green pool lying at the feet of a glacier-fed river. Laguna Esmeralda earns its name; suspended sediment from Ojo del Albino tints the water a jewel tone that shifts with wind and light.

Wildlife
History
The area has long been a seasonal landscape for indigenous Fuegian peoples; later it became a route for shepherding and small-scale settler activities before recreational trekking grew in the 20th century.
Conservation
Peat bogs are ecologically fragile and recover slowly from damage; staying on established trails and not disturbing vegetation helps preserve the watershed and lagoon color.

Waterproof boots and traction
The trail crosses peat and river crossings; waterproof, high-traction boots (and microspikes in winter) will keep you steady and dry.
Layer for wind and sun
Weather shifts rapidly—pack a warm mid-layer and a waterproof shell, plus sunglasses and sunscreen for exposed sections.
Start early for calmer conditions
Morning departures reduce wind on the lagoon and give better light for photos; expect a 6-hour door-to-door schedule.
Respect peat bogs
Stay on the marked trail to avoid fragile peatlands that take years to recover from trampling.
Waterproof hiking boots
Keeps feet dry across peat, streams, and wet trail sections.
Waterproof breathable jacket
Wind- and rain-protection is essential in Tierra del Fuego's changeable weather.
Trekking poles
Helps with balance on boggy, uneven ground and river crossings.
Insulating mid-layer and gloves
Retains warmth during stops and on exposed ridge sections; gloves protect in windy conditions.
