Vajont Gorge

From Longarone a road climbs up (sharp bends, tunnels), passing through the wild Vajont gorge (4km/2.5mi long; galleries through rock), to the Lago di Vajont, a reservoir formed by a dam 265m/765ft high, now largely drained, and then over the Passo di Sant'Osvaldo (827m/2,729ft) to the summer resort of Cimolais (652m/2,152ft).
