A six-hour day hike from Ushuaia delivers mossy lenga forests, peat bog boardwalks and a jewel-toned lake tucked into the Fuegian mountains. This moderate 9 km loop to Laguna Esmeralda pairs dramatic glacial scenery with practical logistics — transfers, lunch and a guide included.
More ways to explore the area's outdoor wonders
You leave Ushuaia before the town wakes fully — a minibus threads a coastal road, then turns inland toward the Tierra Mayor valley. The air thins and the scent of wet peat and Nothofagus leaves grows stronger. At the Nunatak refuge the group shoulders packs, and the trail pulls you into a green world where streams braid through hummocks and century-old lengas and coihues tower over the path like weathered columns.
