A cool wind pushes through lenga and coihue as the trail opens onto a river that seems to lead straight to a green mirror. The path rises and falls across peat-stained hummocks, crossing wooden plank bridges and narrow streams until the bright, sediment-heavy water of Laguna Esmeralda appears, glacial-born and startling against the dark mountains.

A cool wind pushes through lenga and coihue as the trail opens onto a river that seems to lead straight to a green mirror. The path rises and falls across peat-stained hummocks, crossing wooden plank bridges and narrow streams until the bright, sediment-heavy water of Laguna Esmeralda appears, glacial-born and startling against the dark mountains.
This short Andean valley reflects the geological story of Tierra del Fuego: recent glaciation, active erosion and rivers carrying rock flour that lend the lagoon its emerald cast. The area sits on land long used by the Yámana and other indigenous peoples and later charted by European explorers; today the mountains and bogs remain largely wild and quiet.
Expect roughly 4.5 km of one-way hiking (about 9 km round trip) with variable footing — forest trails, boggy sections, and short rocky pitches — gaining modest elevation to about 450 m above sea level. Guides typically drive 19 km from Ushuaia to the trailhead, then lead the walk at a steady pace allowing stops for photos and rest.
Practical tip: layer for wind and rain, wear waterproof boots with good tread, and bring a packed lunch and water. Avoid fragile peat by staying on defined routes and boardwalks; these ecosystems recover slowly. Plan for changeable weather and limited phone reception. For photographers, early or late light softens the mountains and reduces glare on the lagoon; for quieter trails, aim for weekday departures.
This trek pairs a manageable challenge with raw, glacial scenery — clear enough to plan for, wild enough to demand respect.
moderate.
6 hours.
Suitable for hikers with moderate fitness who can handle uneven terrain, short climbs and up to 9 km total distance.
The walk is about 4.5 km one-way (roughly 9 km roundtrip); total outing including transport and stops is around 6 hours.
Yes—expect peat bogs, wet sections and uneven ground; waterproof boots and careful footing are recommended.
No—elevation reaches about 450 m above sea level, so altitude sickness is not a concern for most visitors.
This trek is not recommended for pregnant travelers and requires moderate fitness; operators may set age or health restrictions—check booking requirements.
The valley and lagoon are products of late Quaternary glaciation; the region was historically used by indigenous Yámana peoples and later mapped during Patagonian exploration.
Peat bogs here are fragile and slow to regenerate—stay on designated paths, pack out waste and avoid trampling vegetation to reduce impact.
