Moderately fit — able to handle steady uphill walking and uneven terrain for several hours
An 8‑hour day hike from Ushuaia that moves from peat bogs and Fuegian forest to a rocky ridge beside Laguna de los Témpanos, offering close-up views of Vinciguerra Glacier and on-site climate monitoring stations.
The trail opens like a film: you step out of an air-conditioned van, the town’s harbor shrinks behind you, and a wide valley breathes ahead — peatlands dark and spongy, a ribbon of the Arroyo Grande daring you to keep to the left bank.

The route crosses peat bogs and wet trails year-round; waterproof boots and gaiters keep feet dry and warm.
High reflectivity from ice and water increases UV exposure — wear sunscreen, sunglasses, and a brimmed hat.
Scientific instruments near the glacier monitor climate; do not touch or disturb them.
Save energy for the final steep, loose-rock slope — use poles and take short breaks to avoid slips.
The valley’s peatlands and glacier margins record both post-glacial recovery and rapid retreat in recent decades; researchers placed instruments here to track those changes.
Stick to established trails to protect fragile peat bogs and avoid disturbing research equipment; local operators emphasize leave-no-trace and minimal group impact.
Keeps feet dry crossing peat bogs and muddy sections.
Weather changes fast; layers manage rain, wind and cold near the glacier.
Useful on icy or snowy slopes in late fall, winter and early spring.

Stabilize you on wet boardwalks, stream crossings and the rocky final ascent.
