There is very little tarmac road (only at the start and finish).

Car-free route: depart from Saint-Étienne Bellevue station, accessible by tram from Chateaucreux, and take the L14 regional bus towards Jonzieux. Get off at Planfoy Route du Bourg, paying attention to the timetable, especially on weekdays outside school holidays. It is best to travel in the morning.

The Gouffre d'Enfer dam is one of the most famous sites in the Rhône-Alpes region and a popular walk in the Saint-Étienne area. It was built in 1860 in the Furan valley, near Rochetaillé, and completed 17 years later by the Pas du Riot dam. We then continue along the dam trail to the Pont de Souvignet.
