A 5–6 hour guided trek from Ushuaia to Laguna Esmeralda reveals glacial colors, peat-boardwalk walking and a boxed lunch on a turquoise shore. Expect wet terrain, variable weather, and panoramic mountain views.
More ways to explore the area's outdoor wonders
A wind that smells of glacier and sea meets you on the road out of Ushuaia, and the bus eases into a valley that looks as if someone has brushed it clean. Pines thin, lenga forest opens, and the trail drops you into a landscape that alternates between soft peat bogs, riveted riverbanks and stony moraine. By midday the water appears—an impossible turquoise cleft at the foot of a bowl of mountains—Laguna Esmeralda, a glacial lake that seems to hold the color of the sky.
