Vieyes - Arpissonnet - Bivacco Gontier

The trail from Vieyes to Bivacco Gontier climbs the wooded hillside above the Val di Cogne in Aymavilles, reaching the Mario Gontier bivouac at the Grand Nomenon pasture. The walk starts at Vieyes (1149 m). Trail no. 5 rises through the forest toward Plan Pessey, continues along the stream, passes abandoned buildings and crosses the watercourse on a wooden footbridge toward Petit Nomenon. Continuing uphill leads to the Grand Nomenon plateau and Bivacco Mario Gontier (2302 m). The bivouac, inaugurated in 1985 and dedicated to Mario Gontier, an Aymavilles mountaineer who died in 1983, is equipped with bunks and basic provisions. With 1167 m of ascent over 6.9 km, the E rating reflects a regular, well-frequented itinerary. Recommended from June to October.
