THE ADVENTURE COLLECTIVE® · Independent discovery and booking for outdoor travel
A full-day trek from Ushuaia that threads peat bogs, lenga forest and glacial moraine to a mirror-green lagoon. Expect 8 hours round-trip, wildlife sightings and a riverside lunch.

The minibus hums away from Ushuaia before the mountains close in; asphalt gives way to gravel and the air grows thinner, cold and sharp. After 20 kilometers through the Fuegian range you step out at the Nunatak refuge, strap on poles provided by your guide and set off across a landscape that seems determined to test both balance and attention. Boggy turbales spy at your boots; clear streams run like silver thread; forests of lenga and coihue sway with a wind that has learned the Atlantic’s patience.

The minibus hums away from Ushuaia before the mountains close in; asphalt gives way to gravel and the air grows thinner, cold and sharp. After 20 kilometers through the Fuegian range you step out at the Nunatak refuge, strap on poles provided by your guide and set off across a landscape that seems determined to test both balance and attention.

Two hours of steady walking—sometimes soft boardwalk, sometimes muddy hummocks—bring you to the Emerald Lagoon. The name isn’t marketing: the water takes on a green so clear your reflection looks painted. The lagoon sits in a glacial hollow, hemmed by the low peaks of Tierra del Fuego and framed by terraces of peat and wind-smoothed lenga trunks. Guides spread out lunch on the bank—sandwiches, fruit and a hot drink—and the group leans into the quiet. Condors wheel above; a fox pads the treeline at a respectful distance; there’s always the possibility of spotting beavers near the shore where they’ve altered the wetland geometry.
This is landscape shaped by ice and ocean. The lagoon is a glacial tarn within the Tierra del Fuego Nature and Landscape Reserve, an area that records the struggle between Atlantic winds and Andean geology. The trail follows old moraines and crosses peatlands that developed over millennia; where the ground is soft, life adapts with stunted yet hardy plants and mosses that carpet the open. The human history here is shorter but meaningful: European route-building, sheep ranching and modern conservation have all left marks; today the refuge and park rangers balance access with protection.
Practicalities are simple but matter: expect a full 8-hour day including transfers, moderate effort and variable weather. Footwear should be high-cut and waterproof; gaiters earn their keep. Bring layered insulation, rain protection and at least 1.5 liters of water—colder air tricks you into drinking less than you should. Leave no trace: the peat bogs recover slowly, and trail braiding accelerates erosion.
On return the trail offers a different mood—the light slants, the forest grows denser, and you notice small things: a beaver-chewed stick, a feather from a condor, the faint smell of peat smoke from distant cookfires. The trek is not a technical climb; it asks instead for respect for soft ground, steady legs and curiosity. For an accessible but wild day in Tierra del Fuego, the Laguna Esmeralda circuit delivers a compact, honest slice of Patagonia’s edge.
moderate.
8 hours (including transfers).
Moderate fitness: comfortable walking on uneven, sometimes boggy terrain for up to 5 hours of hiking
The trekking portion is roughly 4–5 hours of walking (2 hours each way plus a 1-hour lunch) with the full tour lasting about 8 hours including transfers.
The operator recommends the trek for ages 8 and up; children should be comfortable walking on uneven ground and in cool conditions.
Yes—guides typically provide trekking poles and basic gaiters if terrain requires them.
Wildlife sightings such as condors, foxes and beavers are possible but not guaranteed; bring binoculars for better viewing.
Waterproof, high-cut hiking boots and gaiters are recommended to handle peat bogs and stream crossings.
A riverside lunch and bottled water are included, but bringing extra snacks and a refillable water bottle is advised.
The area lies within the Tierra del Fuego Nature and Landscape Reserve, protected for its unique post-glacial landscapes and peatlands that record thousands of years of climatic shifts.
The peat bogs and turbales recover slowly from disturbance—stay on established paths and pack out waste to minimize impacts.
Antartur Adventure operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
