The Essential is a route that condenses the most beautiful sites of the Bernese Jura, hence its name.

This Essential route demands good physical preparation for those wishing to take on a challenge by covering a distance close to a marathon, but in the heart of nature, with the added challenge of significant elevation gain.
After a steep climb to the ridge, a rapid and challenging descent to Cortébert awaits, which can be quite demanding.
The trail then leads you to Chasseral and its antenna before descending through the magnificent Combe-Grède via a technical path.
From St-Imier, the route ascends via the Col du Sergent to reach the Mt-Crosin wind farm and its welcome refreshment station.
A final push takes you to Tramelan and the finish line.

This "Essential" route requires good physical preparation for those wishing to take on a challenge by covering a distance close to a marathon, but in the heart of nature, with the added challenge of significant elevation gain. After climbing to the ridge, you'll pass through the Mt-Crosin wind farm before descending to Villeret. Next comes the climb to Chasseral through the heart of the Combe-Grède valley. Weather permitting, you'll see the entire Three Lakes region with the Alps as a backdrop during the descent back to the Place Centrale. A descent to Cortébert leads to the final challenge: a steep climb to reach the ridge, followed by a descent to the finish line.
