This one hundred and forty-two-kilometre tour requires a day. It is operable throughout the year.
It leaves from Malargüe southwards, through National Route 40, passing by the ruins of Fuerte Malargüe. Sixty kilometres farther there is a detour to the right, two kilometres before reaching Bardas Blancas, you will arrive by a dirt road to the Caverna de las Brujas on the Moncol Hill. This is a geological formation of impressive features, both for its magnitude, and because of the ways that salt and water have generated stalactites, stalagmites, robes, veils, columns, stony corals, chimneys and countless galleries that can be appreciated in all its magnitude through the strategic lighting and experienced guides who accompany the tourist. The time required to tour the whole cave is almost three hours. It is currently a provincial reservation. The return is done through the same way, although there are three options to enrich this circuit. The first is the visit to the petrified forest of Llano Blanco, fifteen kilometres from Bardas Blancas. The second is a visit to La Pasarela, place where the Rio Grande runs through a twelve meters wide gorge (a visit to the Cavern plus one of these can be done in the same day), and the third is to enter the mountain through the Provincial route 224 to El Paso Pehuenche on the border with Chile.
