Small pass, ideal as a starting point for hikes

Viewpoint above the Doubs source with beautiful views through a forest clearing to Mouthe and the Doubs river.

The source of the Doubs River is a powerful karst spring in a heavily karstified area of the Jura Mountains. It lies at an altitude of 937 meters at the foot of the forested, up to 1,419-meter-high Mont Risoux mountain range, which straddles the border between France and Switzerland. The Doubs River rises from a small, approximately five-meter-deep spring basin in a cave in the rock.

The route up from Biere on the Swiss side is a solid steady climb with a few 12% and 13% sections. Traffic is quite light and the road is excellent. The trees give some nice protection from the sun and wind. Crossing the col northwards takes you down to the Vallé de Joux on a pretty steep decent with great corners and some short straights. My brakes made sounds I have never heard before! I did this and Col de Mollendrux together for a great 80k / 1,500 m ride. Recommended.

The route climbs at an average rate, although it also reaches a peak of 11% (briefly). Overall, it's a very pleasant ride, and the forest provides shade when needed, making the climb more bearable. Overall, it's a better alternative for cyclists than the main D47 road via Les Gras directly towards Pontarlier. It's also less busy and offers more variety, alternating between meadows and forest sections.

The ride up the Col du Marchairuz is a truly stunning landscape. From the Vallé de Joux and the village of Le Brassus, the initial climb is somewhat steeper, through beautiful Jura forests and meadows to a wide intermediate plateau. There, the road runs in a perfectly straight line. Perfect for preparing yourself for the short, tough final climb to the pass at 1,449 meters. A restaurant awaits you at the top of the pass, open Wednesday to Sunday. To get a view of Lake Geneva, you'll have to descend slightly on the other side, as the trees are in the way.

Pass with small kiosk

You can get a coffee at the bike/cross-country ski rental shop in the parking lot. It's worth it.
