Important note regarding parking: Chemin des Salettes, which provides access to the above-mentioned car park, is a one-way street and reserved for residents. You must therefore park in the Champ de Mars car park (paying) and walk up Chemin des Salettes to reach the starting point.
(S/E) Go to the EDF station and turn right onto the wide track that leads to Fort des Salettes.
(1) After the Via Ferrata crossroads, leave the track on your left and take the markedGR® trail opposite (this is a variant ofthe GR®5). Reach the track just below and before the Fort.
(2) Turn left (sign) onto the path that climbs after a first hairpin bend.
(3) Leave the Rocher de l'Ombre trail on your right and continue on the GR®. The slope is steady without being too steep, and the numerous hairpin bends make it easier to climb.
After about 45 minutes, you will reach the Fontaine de Bon Repos.
(4) Continue to the last bend before embarking on a long uphill traverse that ends at the Croix de Toulouse.
(5) Take the same route back to the car park (S/E).
There was quite a bit of mud, but we were happy to descend on the other side.
