Cerro Tronador is the highest mountain in the National Park Nahuel Huapi with three choices in its summit - one Chilean, one international, and one Argentinean. To arrive at its base from San Carlos de Bariloche it is necessary to take the national route #258 heading for El Bolsón and then, to arrive at the south part of Lake Mascardi, take the route #254 towards the right until arriving to Pampa Linda, a small village that has a hostel with a restaurant, camping site, park guard, and a section of Gendarmería Nacional.

From here, you will see several paths for trips by foot or by horse that will allow you to discover places of an extraordinary beauty. You can admire, for example, the Manso Glacier or the snowdrift Negro, which together birth the Manso Superior River that ends in Lake Mascardi after travelling through the Valley of the Vuriloches.

You could also head to Otto Meiling refuge, located 2,000 metres high, from where the ascent to the summits of the Tronador begins (experts only). Tronador is 3450 metres high and owes its name to the impressive noise that is made by large detachments of ice. Explore its surroundings on this tour with return transport.
