L'Essentielle is a route which condenses the most beautiful sites of the Bernese Jura, hence its name.

This course requires good physical preparation for those who wish to take up a challenge by covering a distance close to a marathon but in the middle of nature, with the height difference in addition. In particular, it will take trailers to the Mt-Soleil wind farm, to the Chassera branch via Combe-Grède and to the Anabaptists bridge.
