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 (two hours roundtrip), offering great views. If you have a car, you can hire a guide in town (ask at the tourist office) and drive to the Reserva Integral (four to five hours roundtrip) to see some cave paintings.
