This trail passes through two Nature Parks, the Doubs and the Chasseral Parks, from the Franches-Montanges to the summit of Mont-Soleil. On the way, admire the sparkling water of the Étang de la Gruère.

“We took our bikes off the train in Tramelan and set off to discover the largest renewable energy park in Switzerland, located on the sites of Mt-Soleil and Mont-Crosin. The route was very pleasant, though it was a bit difficult to begin with. The next stop was at the natural pond la Gruère, where we took the time to share our impressions among the six of us, whilst quietly enjoying the end of the day in this extraordinary setting.”
