Col du Sanetsch – Legendary Mountain Passes

Col du Sanetsch

Les Coteaux du Soleil

This climb is one of the finest and most demanding in Valais. Starting in the Rhône Valley and culminating at 2,200 metres, this is an ascent that demands respect!




24.25 km


2:30 h


Covering a total altitude difference of 1,800 metres, the Col du Sanetsch route is without doubt the most demanding climb in Valais. From the valley, you first cycle through the vineyards of the municipality of Savièse, then the larch and spruce forests of the municipality of Conthey, before passing through alpine pastures and finally reaching the magnificent Tsanfleuron glacier. At each bend, the road reveals another surprise, including rock faces, waterfalls and snow-capped peaks, as more and more stunning landscapes come into view. The route gradually takes you through narrow, shady gorges lined with cool, fragrant forests. After a few brief but welcome level sections, the climb picks up again with even more gusto, offering a view of the now-distant Rhône Valley. Once you've tackled a few hairpin bends and passed by a waterfall, you’ll gradually find yourself in a landscape of alpine meadows. Cycle through a tunnel carved into the rock and your determination will be rewarded with a close-up view of the limestone pavements of the Tsanfleuron glacier.

Turn-by-turn directions

The suggested route for climbing the Col du Sanetsch starts in Conthey and passes through the villages of Vuisse and Chandolin (Savièse) to avoid the traffic on the road through Erde (Conthey). Starting from Conthey, cross the bridge that leads to the left side of the Morge valley and follow the signs to the villages of Vuisse and Chandolin, then continue in the direction of the Col du Sanetsch. After a brief descent of one kilometre, climb towards the Pont du Diable to reach the Erde-Sanetsch road, which you follow all the way up to the summit of the Col du Sanetsch. There are Valais cycle signs throughout this legendary climb.

Author's recommendation

From the Col du Sanetsch, head to Gsteig via a short cable car journey that makes for a unique and thrilling experience, then return to central Valais via the Col du Pillon with the wind at your back.
