The trail runs across the water divide; the sensitive vegetation in the furthermost section is protected against destruction from footsteps with wooden slats. A guide in the form of postcards is available for 5 francs from the regional tourist office.
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.
