VAL DE BAGNES: A GRAVEL BIKING HOTSPOT IN THE ALPS
Located in the Swiss region of Valais, the Val de Bagnes is the land of raclette. But it’s also one of the best alpine gravel destinations in the Alps, still little-known outside a small circle of insiders. Here in the heart of Verbier’s mountain playground, the dirt roads are of excellent quality and the scenery is spectacular, with some of the highest peaks in the Alps as a backdrop, such as the Grand Combin (4,314 m).
I live close by and let me tell you, there’s no shortage of options. Let’s start with this route I designed from Le Châble, just below Verbier, linking some of the region’s most beautiful gravel sections. It's a must for gravel riders visiting during the Verbier Bike Festival or at any time during summer.
From the start, there’s no easing in—it climbs, and it’s steep. Pavement and gravel alternate. But unless you overheat like I did here with my buddy Mike during a bikepacking trip (story here), you should be able to stay in the saddle.

It's getting interesting
Around kilometer 10, you see exactly why you came: a smooth gravel track, views over the surrounding peaks… life doesn’t get much better. Higher up, the slope stiffens and the surface gets rougher. You have to push hard on the pedals, but soon you pass the magic 2,000 m mark, where trees grow sparse and then disappear entirely. The scenery turns rocky—welcome to the high mountains.

Approaching treeline
After more than 15 km of climbing, you reach La Chaux. If you’re feeling brave (or reckless), you can keep going up toward the Col des Gentianes. I did it with the cheerful Lausanne Gravel crew and… I don’t recommend it. Even if riding close to 3,000 m is pretty cool.

Refueling with a view: the Grand Combin (4314m)
Instead, you can cruise almost flat for 8 km with a plunging view over Verbier—the very place where Alberto Contador won a Tour de France stage in 2009. And where do you end up? At the Col de la Croix de Cœur, the finish line of the famous Tour des Stations sportive. This corner of the Swiss Alps is truly a paradise for cycling.

Time to go down towards La Tzoumaz
The descent to La Tzoumaz follows the narrow road from the Col de la Croix de Cœur. Just below the 4 Vallées ski area, a hairpin bend leads you into a superb forest gravel traverse, complete with a tunnel where you might come out a bit damp.
You then join the road to the Col du Lein and start climbing again, on pavement with a short gravel section at the top. (See here for a road cycling loop that includes both the Col de la Croix de Cœur and the Col du Lein.)

Between Col du Lein and Col du Tronc
Back in the Val de Bagnes, it’s time to celebrate—with a downhill ride to the Col du Tronc! Yes, anything is possible here. The icing on the cake: flawless gravel all the way to the entrance of Levron, where you meet the Col du Lein road again. But not for long: before Vollèges, you turn left for one last epic gravel sector before returning to Le Châble. Time for raclette!
