Depart from the Chalet-Hôtel du Giobernay car park at the end of the Valgaudemar Valley.
(S/E) Take the path on the right as the valley continues. Quickly cross the Torrent de Muande Bellone and continue towards the shepherd's hut. Go around it on the right to respect the shepherds' living space and continue up the Vallon du Giobernay. Just after the hut, ignore the path on the right that leads to a footbridge. Continue climbing, cross the Torrent du Vaccivier and quickly begin the steep climb up the switchbacks to reach the Cabane du Vaccivier under its rock.
(1) Continue along the path that branches off to the left. This path continues with a steep climb, crosses the stream several times and arrives at a flatter section. Continue along the hillside, passing a path on the right leading to the Cirque Glaciaire du Giobernay, before going around the ridge (you may need to use your hands to help you) and reaching the Refuge du Pigeonnier.
(2) From the refuge, begin the descent via an easier, less steep path. This path winds its way down and joins the Torrent de Muande Bellone. Cross the various branches of the torrent and a few metres further on you will reach a junction.
(3) Continue the descent by following the stream on the right bank and return to the starting point at the Chalet-Hôtel du Giobernay car park (S/E).
