Parc du Doubs - This "pearl of the Jura" is a medieval little town on the Doubs river with a prestigious history. Century-old buildings such as the collegiate church from the 12th century and its cloisters testify to this.

This hike does full justice to its name. The trail leads from Les Brenets near La Chaux-de-Fonds to St. Ursanne, almost always alongside the River Doubs and crossing the Doubs Regional National Park from west to east.
Leave the wild nature behind you and slowly come back to the real world before reaching the medieval town of St-Ursanne. There, the Doubs makes a sharp turn; perhaps this is where it gets ist name from - dubitus meaning the hesitant in Latin.
