The wonderful pasture valley of Erera-Brendol opens on a karstic plateau surrounded by a rocky amphitheater.
Piani Eterni, covered by a blanket of Mugo Pines, conceal cunning cracks and karst swallow holes, the deepest of which goes down for over 960 meters.
The group includes the grassy summits of Col del Demonio (1,919m), Brendol (2,160m), Palon (2,069m) and Mt. Mondo (2,039m). Eastwards, beyond the pastures of Campotorondo, Col Dorin (2,110m), Prabello (2,073m) and Agnelezze (2,140m) rise.
