Park in the Les Barnets car park.
As this is a winter route, it does not necessarily follow the paths shown on the IGN map.
(S/E) Take the forest track that climbs gently towards the Chalet des Allières. Head due south to the refuge.
(1) Continue south for about 200 metres, then turn left into the forest. Follow the yellow markings on the signposted route until you emerge from the woods into the Vallon de Combe Oursière.
(2) Once out of the woods, head up the valley on the right (south-east) towards the summit. You’ll reach a small pass; continue up to the left – the summit cross is just a few metres away. From the summit, there’s a magnificent view of Grenoble, the Taillefer and the Belledonne.
(3) The return journey follows (more or less) the same route back to the car park (S/E).
