Leaving Bariloche, we head south on Route 40 (which goes to El Bolsón), after passing through Lake Gutierrez and Lake Mascardi, we turn right along the road to Tronador. It leads to the Manso Medio River, where it forks. There, instead of crossing the bridge over the river, we continue along the path passing through Los Moscos and Hess lakes. Then we cross the bridge over the Roca River and arrive at a parking lot, from here the tour continues on foot and after a short walk we arrive at the Los Alerces Waterfall Viewpoint. It is a beautiful 20-meter-high jump made by the Manso River on its way shortly after leaving Lake Hess. This river of cold and crystalline waters has the peculiarity of flowing into the Pacific Ocean, in Chile. The waterfall can be seen from a wide viewpoint, surrounded by a dense forest of tall coihues and humid walls full of ferns and mosses. In this sector, the forest has the peculiarity of having some specimens of larches, hence the name of the waterfall. Then we continue the journey to Pampa Linda, an obligatory stop for lunch. At the end of lunch we continue the journey to the end of the road and arrive at the foot of the highest mountain in the National Park, Cerro Tronador, so called because of the sound produced by the breaking and detachment of the glaciers lodged in its summits. From this point you can see the Río Manso Glacier, commonly called "Ventisquero Negro", thus reaching the end of the route. From here we start the return to Bariloche.
