Pointe de Ronce is located near the Mont Cenis Pass and overlooks the village of Lanslebourg in Haute-Maurienne.

From the summit, a long ridge stretches south-east to Pointe du Lamet (3,504 m), Roche Michel (2,885 m) and to Rocciamelone.

Arrived in Plan des Fontainettes (2,090 m) starting at the characteristic pyramid-shaped church, walk to Fort de Ronce.

Near the Fort, start heading north on a long path that goes with large coils to reach Col du Lou (3,042 m).

Downhill you can retrace the ascent route or you can go down the southeastern slope of the mountain, through the Pointe du Lamet, and then go down to the Lake of Mont-Cenis.
