Ardèvaz

Ardèvaz (L'Ardève) is a mountain of roughly 1,500 m in the Swiss canton of Valais, rising above the municipality of Chamoson, home to the village of Saint-Pierre-de-Clages. It overlooks the Rhône valley and drops away in tall rock faces on its southern side. For hikers it offers a demanding but compact outing by Alpine standards.

Where is Ardèvaz?

The peak belongs to the massif between Chamoson and the mountain resort of Ovronnaz. Its summit stands less than 200 m higher than Ovronnaz, so the climb from that side is fairly short. From the valley floor, many walkers start around Saint-Pierre-de-Clages, a village known for its Romanesque church and book festival, then continue up to the Mayens de Chamoson, a hillside settlement of former seasonal farm chalets that now serve as holiday homes.

How do you climb Ardèvaz?

Chamoson's municipal brochure describes a route from the Mayens de Chamoson, near the Hôtel de l'Ardève, to the top. The circuit covers about 9.5 km with some 780 m of ascent and takes around 3 hours 45 minutes. The municipality rates it medium difficulty.

The other common starting point is Ovronnaz. The official "Mayens-de-Chamoson Tour" is about 15 km, graded expert, with around 790 m of climbing and descent and a duration near 4 hours 20 minutes. Ardève is the high point of the loop, reached along the ridge. Several exposed passages on the crest are secured with chains and iron handrails. After the summit you retrace your steps for about 200 m, then follow the Lachat forest road down for roughly 4 km, climb toward the Mayens de Chamoson and return to Ovronnaz.

What will you see?

The ridge opens onto the Rhône valley, with the vineyards of Chamoson and Leytron below and the surrounding Bernese and Pennine Alps beyond. On the south side, the vertical cliffs are the main spectacle, with the path running above them. The area is also wine country: wineries in Saint-Pierre-de-Clages bottle Petite Arvine, a white grape typical of Valais.

When should you go?

The municipality recommends hiking from April to October. In spring and autumn the slopes are clear of snow, while in high summer the valley gets hot, so an early start works best. After rain, the rock and the metal protection are slippery, so postpone the climb in wet conditions. Hiking boots and a head for heights are essential.
