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

This trail has a lot of stones and rock slabs (be careful of slipping!). There are also a few roots at times. Otherwise, the gradient is generally reasonable, except for a brief section of switchbacks that crosses a rockfall zone (a few meters of pushing is expected for most mountain bikers).

A typical Jura ridge trail: cliff on one side, forest on the other, sharp rocks and large roots peeking out, and constant steep sections (uphill and downhill). It's not the worst I've seen: aside from the steep sections, no section is technically impossible for an experienced mountain biker. The view of the Grand Crêt d'Eau, the Crêt de Chalam, and the Haut-Jura is also pretty good.
