9 hours
Suitable for average fitness; walking involves short, low-elevation trails and standing at viewpoints for up to 3 hours total.
A full-day loop from Bariloche to the foot of Cerro Tronador that delivers lake views, river valleys and the dramatic Ventisquero Negro. Expect short hikes, gravel roads, and glacier-front vistas on a nine-hour outing suitable for most fitness levels.
You leave Bariloche before the town wakes fully: the bus eases out of the lakeside grid, green hills folding toward a horizon that grows teeth—dark, glaciated peaks rising against a pale Patagonian sky. By the time the driver pulls off onto a gravel road the air has the bright cold of mountain rivers; the first stop, Lake Mascardi, opens like a pale mirror framed by lenga and coihue, and you realize the day is as much about the approach as the mountain itself.

Patagonian mountain weather changes fast; bring a windproof shell and insulating mid-layer you can add or remove during stops.
There are no guaranteed potable refill points on the route—carry water and light snacks for the 3+ hours spent at Pampa Linda and viewpoints.
Trails are dirt, rooty and sometimes muddy; ankle-supporting day hikers or light trekking boots make short walks more comfortable.
High UV and reflective snow mean sunscreen, sunglasses and a brimmed hat are useful even on cool days.
The Nahuel Huapi region was historically traversed by Mapuche and Tehuelche communities and later mapped during 19th-century Argentine expeditions; Cerro Tronador became a landmark for border surveys between Argentina and Chile.
Nahuel Huapi National Park protects fragile glacial environments; stay on designated tracks and avoid collecting stones or disturbing vegetation to limit erosion and habitat loss.
Blocks wind and sudden showers common in the Andes.
