Start from the Col des Aravis. You can also park in the car park opposite the chapel, behind a souvenir shop.
(S/E) Take the mountain pasture track that starts at the south-east corner of the car park. Continue to a small car park at the side of the track before entering the woodland.
(1) Continue along the mountain pasture track until you reach a wide right-hand bend on a ridge. Leave the track and climb a few metres up to reach an orientation table.
(2) Return to the track and follow it, ignoring the turn-offs to the right and left leading to the alpine chalets. Pass in front of a chalet-inn at a place called Plan Rebord, then the bottom of the Ruisseau du Foiroux valley and two tight hairpin bends. About a hundred metres further on, you’ll find the start of a path on the right.
(3) Continue along the track for a round trip to the Chalet du Curé. Perched on its promontory, it is easily recognisable by its distinctive architecture (private property).
(4) From the Chalet du Curé, return to the start of the path.
(3) Follow the path as it climbs through the mountain pastures. It turns right and follows the summit section of the ridge.
(5) At the Croix des Frêtes, continue climbing for a few metres, then follow the ridge until you reach the base of the cliffs. The path branches off to the right, running almost level with the ground. When you reach a ravine, descend for about fifty metres to cross it, then climb back up to rejoin the ledge-like path and reach a small pass.
(6) Leave the main path and turn right towards the sharp limestone pavement. Cross over and descend to the other side.
Please note: you’ll need to use your hands to help you descend a step of about 2 metres.
If this seems too difficult, you can go round the sharp limestone pavement on the left by continuing along the main path and then turning right further down.
Continue along the edge of the ridge on a narrow path until you reach its end. Just before this, turn left into a small valley and go round the rocky outcrop, curving to the right. Resume the descent along the ridge and reach the Croix de Fer.
(7) From the cross, take a faint, grassy path that follows the base of the promontory you descended earlier and leads towards the valley to an alpine chalet.
(8) Continue straight on down the slope and reach the (barely visible) catchment point of the Source des Aravis.
(9) Ford the stream (dry at the end of August 2019) and follow the path down the left bank.
(1) Join the track on the left and head for the Col des Aravis (S/E).
