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.

pretty small stone viaduct with 2 superimposed lanes, one for cars with 6 arches and one for the train with 11 arches. Atypical.

Beautiful, simple, easy walk; lots of traffic noise on the "road" section, a bit of a shame, but the color of the water is magical
