Departure from the Crépon car park below and before the Chalet-Hôtel du Giobernay on the D480t.
(S/E) At the car park entrance, take the path that leads to the stream. Cross the stream via a footbridge and continue uphill until you reach a crossroads.
(1) Leave the path on the left that goes uphill and continue straight ahead towards the Chabournéou and Vallonpierre refuges via the Sentier du Ministre. Continue along the hillside and reach the next crossroads.
(2) Ignore the paths branching off to either side and continue straight ahead. Cross a footbridge and continue up the Séveraisse valley.
(3) At the three-way junction, ignore the path on the right leading to the Vallonpierre refuge and follow the path opposite, which climbs gradually towards the Chabournéou refuge.
(4) Cross the stream via a footbridge and climb more steeply to reach the refuge.
(5) Continue above the refuge, pass a small hut on your left and start a curve to the left to cross the Torrent de Chabournéou on a footbridge.
(6) Ignore the less visible path on the right and follow the path on the left, which continues along the hillside. This path passes opposite the Refuge de Chabournéou, then begins a short climb in hairpin bends to pass the rocky ridge and easily reach the Beaume Rousse balconies.
(7) The path begins a gradual descent to go around a rocky ridge and, after a short climb, reaches the Torrent du Pis. Ford the two arms of the torrent and reach the Cabane du Pis a few metres further on.
(8) Continue for about 200 metres and find a more discreet start on the right. Leave the main trail as it descends and begin the ascent on the right (not marked on the IGN map). Join the main trail that climbs up from the valley and, after a few switchbacks and a steady climb, reach the mountain pastures of the Tirière plateau. Follow the trail as it climbs gently and reach the ruins of the Cabane de Tirière on a flat area.
(9) Begin the descent by following the path, which continues along a balcony and then winds before reaching the larch forest. You will reach a crossroads at the edge of the forest before the Torrent du Gioberney.
(10) Do not cross the torrent; instead, turn left towards the Crépon car park. The path descends gradually along the left bank of the Gioberney Torrent and returns to the starting point.
(1) Take the path on the right and, after crossing the torrent, head for the Crépon car park (S/E).
