Mount Tronador (Pampa Linda Village)
Cerro Tronador, standing at 3,491m, is the highest mountain in the Lake District region around San Carlos de Bariloche. Tronador means 'thunderer' and that really is the sound you hear on approach, as ice calves off the glaciers into a natural amphitheatre below.
With a day hike from Bariloche you can get up close to its glaciers. It's also possible to climb Tronador; this is a 3 day expedition, summitting on Day 2, and using the Meiling mountain hut on the first and second nights. There are actually a few different peaks on Tronador and for introductory/intermediate trips you'd tackle the 'Pico Argentino' at 3,187m.
Tronador lies in the heart of Nahuel Huapi National Park, and is accessed via Pampa Linda, a short drive from San Carlos de Bariloche. It is also the source of the Manso River, one of the top white water rafting rivers in the region.
