The start at Porrentruy is as follows. From the starting point, Porrentruy, the residence of a former prince-bishop, the route leads at first through the gently rolling hills of the Ajoie, an agricultural region. Influenced by its neighbor, France, as regards landscape, climate and culture, the Ajoie is quite distinct from the rest of the Jura along the Trans-Swiss-Trail-Route. The Trans Swiss Trail exhibits a spectacular change of scenery already during its first stage, when the ascent to the forested Jura crest at Les Chainions is followed by the descent to the deeply cut valley of the Doubs River.
The careful planning of a tour will ensure that you also derive the maximum pleasure and enjoyment from it. Please take the time to contact the local information centre and enquire about route and weather conditions before setting off. Your intended trail may be fully or partially closed, depending on the time of year and weather conditions.
