The exciting mountain trail is of medium difficulty, but can be more challenging in late fall or early spring due to the presence of ice, snow and mud on the slope. To explore it, it is necessary to use trekking boots and waterproof clothing all year round. The tour begins at a gate located at the bottom of the Andorra Valley, about 8 kilometres from the centre of Ushuaia. Crossing a large peat bog, you must walk along the left bank of the Arroyo Grande. Once you cross the bridge, you enter a forest area where the trail becomes more passable, with some climbs that require a bit of physical demand. When we reach the end of the vegetation, we see the last stretch of the trail: the ascent up a rocky slope that leads to the shore of the Laguna de los Témpanos. 1 kilometre from the bridge is the fork that leads to the Enchanted Lagoon. At the source of the watercourse and in the glacier mass, measurement elements are observed that serve to monitor the behaviour of the glaciers and their relationship with the phenomenon of Climate Change. Please do not touch them.
