Cerro Tronador is located in the southern part of the Andes mountain range, on the border between Argentina and Chile. It separates two national parks: Nahuel Huapi, in the provinces of Río Negro and Neuquén, Argentina; and the Vicente Pérez Rosales in the province of Llanquihue, Chile.

The name of the hill is due to the noise that is produced by the frequent detachments of ice in the glaciers, similar to that of thunder. El Tronador has a total of seven glaciers which are currently in remission due to global warming.

The tour departs from Bariloche, taking National Route 40 South, about 45 km, to cross the Pampa de Huenuleo and border Lake Gutiérrez, to cross the Pilmayen and Melgarejo streams. After passing through the “water divide”, you will travel along the banks of Lake Mascardi until you reach the detour where the road to Tronador (gravel) emerges.

During this tour, Lake Mascardi is bordered again along its west coast, until reaching the Isla Corazón viewpoint. Further on, you will pass in front of Cerro Los Emparedados and border the upper Manso River until you reach Pampa Linda, from where you have one of the best views of Cerro Tronador.

Then you cross part of the Vuriloches valley and finally, passing through a shady forest, you reach the Ventisquero Negro.

The tour ends a little further on at the foot of Cerro Tronador. The hill, with its 3,454 metres above sea level, is the highest point in the Nahuel Huapi National Park, and has three peaks (International, Argentine and Chilean).
