Col du Tronc – Legendary Mountain Passes

For the first few kilometres, you follow the inverse route itinerary of the Col du Lein from the Val de Bagnes. The Col du Tronc summits on the ridge that links the Col des Planches to the Col du Lein. This atypical climb completes this triple ascension of the mountain.

From the Val de Bagnes, the Col du Tronc heads towards the summit of the Pierre Avoi through the mountain pastures. The 11.6 kilometres of climbing to 1,606 metres of altitude are on a steady slope for the length of the ascent. The peculiarity of this pass is that the second half of the course is on dirt road. Therefore, it will delight gravel bike users as well as adventurous road cyclists! At the summit of the pass, you have the possibility of turning left towards the Col des Planches below or right in order to climb to the summit of the Col du Lein just a few hundred metres above.

Turn-by-turn directions

Leaving the village of Vollèges behind, the Col du Tronc takes you climbing quickly above the Val de Bagnes – the valley that is home to the famous mountain resort of Verbier. First as you pedal through meadows then forest, this climb allows you to view a unique panorama: the Catogne, the Tête de la Payanne and the Mont Rogneux are just a few of the summits that you can admire! Half-way through the climb, the paved road transforms into a dirt road, transporting you back to the early days of road racing when the “forçats de la route”, the hardened road riders of the era, would climb over the unpaved alpine passes. It’s a safe bet that you will take a few moments to pretend to be Gino Bartali or Fausto Coppi! At the top you will discover some stunning views of the Valais between coniferous trees at the top of the pass.
