Route Snapshot

The hike to Refugio Otto Meiling covers approximately 28 km return from Pampa Linda, with around 1,050 meters of elevation gain. The trail climbs steadily through Andean forest before emerging into exposed alpine terrain beneath the glaciers of Cerro Tronador.

The highest point of the hike is roughly 1,900 meters at the refuge. While the altitude is moderate, wind exposure and rapidly changing mountain weather can increase the perceived difficulty.

The standard trail is non-technical and well-defined. The primary challenge is sustained uphill effort on the first day and the long descent on return.
