East of the Andes, in the Provinces of Rio Negro and Neuquen, two pituresque towns can be visited: San Carlos de Bariloche and San Martín de los Andes. From
San Martín de los Andes it's easy to reach the Parque Nacional Lanín with it's Lago Huechulafquen in a few of hours. This nice broad valley
offers good views on the Volcano Lanín.
