Visit the black glacier (ventisquero negro), see the Cerro Tronador and a waterfall over an overhanging cliff named Saltillo de las Nalcas, near the village of Pampa Linda. The busride takes about two hours, and costs AR$90 return or AR$45 one-way (Transitando, 20 de Febrero 300, Bariloche). There is an additional entrance fee to the national park of AR$50 (foreigners). With this bus, you have to hike the last 7 km to the glacier, which is a beautiful experience as there is a hiking trail and the road shows amazing landscape. Some tourist buses take you right to the sights. Near the lookout there is confiteria which sells overpriced food although location is remote and the place astonishing.
