Parque Provincial Ernesto Tornquist
This 67-sq-km park , 25km from Sierra de la Ventana, draws visitors from throughout the province. There are two entrances. The first is 5km west of Villa Ventana and home to the Centro de Visitantes , which has a small display on local ecology. The main hike here is Cerro Bahía Blanca (three hours roundtrip), offering great views.
