Park at the exit of Saint-Pierre-de-Chartreuse towards Raidlight / Oréade or a little further along the road (Route de Perquelin).
(S/E) Take the path at the Croix Saint-Claude hiking sign, located at the village exit by the crossed-out Saint-Pierre sign. This is theGRP® Traversée de Chartreuse trail, marked in yellow and red. It climbs quite steeply. You’ll soon reach a sign for the “Chemin des Amoureux”.
Continue to the right on theGRP®. The path zigzags up a steep slope and reaches the hamlet of Becete.
(1) Continue to the right, staying on theGRP®. Walk carefully along the cliff face of the Rochers du Mollard. You will need to hold on to children and reassure anyone who is prone to vertigo.
You will reach the “Le Mollard” sign at a three-way junction.
(2) Turn right onto the almost flat, or even slightly descending, path to continue on theGRP® Chartreuse. The path continues to run alongside the cliff but at a greater distance. You will reach a forest track. Turn left after a few steps.
(3) Leave this forest road by turning right onto a path. At the second hairpin bend, you’ll emerge from the forest into a clearing where the path heads right, remaining almost flat. After a few trees, the path opens out into a meadow and leads to Bellecôte.
(4) Continue straight ahead. From here, the path is undulating (mostly downhill) through a beautiful forest to the small pass of the Collet de la Saulce.
(5) Keep straight on theGRP® to reach the Cabane de Bellefont.
(6) Follow the same route back to the previous junction.
(5) Turn left onto the yellow-marked path. You will soon reach a section where the path has been washed away. You must go round this landslide from the upstream side. You will rejoin the yellow markings before reaching the Ruisseau de Bellefont.
(7) Follow the stream, paying attention to changes in direction where you need to leave the road and rejoin the path, which often winds beneath the forest track. Cross several small streams to reach the forest track that runs alongside the Ruisseau du Guiers Mort or de Saulce (depending on the route).
(8) Take this track to reach the hamlet of Perquelin.
(9) Continue along the tarmac road until you reach a junction. Turn right to return to the starting car park in Saint-Pierre-de-Chartreuse (S/E).
