The passage is located at the level of the tunnel of the same name.

The Marron ponds are named after a family from Brénod, it is not a reference to the color of the water. Only one of them remains filled with water all year round. This one served as a water reserve and fishing spot for the monks of the Meyriat abbey. In spring, a multitude of water lilies cover the surface.

Nestled in the Semine valley, Saint-Germain-de-Joux offers a preserved natural setting. Don't miss the "marmites de géants" (giant's cauldrons), these rock formations carved by water, accessible from the village.

beautiful pass, quite rolling especially through St Germain de Joux, a little tougher on the Saint Claude side. lots of writing on the ground since the Tour de France passed through.

A 10 km climb from the small roundabout in Châtillon, it's more like 14 km from the Nantua road or the center of Bellegarde. The gradient is fairly steady, ranging from 5.5% to 7.2%, with about ten small steep sections at +8.5%. Very quiet, with very few cars. The road is generally in good condition, but nothing more. There are some beautiful views along the way.
