Getting There

From France - Chamonix-Montenvers - (Refuge de Leschaux)
Follow the Mer de Glace (same as for Rif. du Requin) until it turns to right.
Now you have to cross it (red marks) until the lateral moraine to get the Glacier de Leschaux.
Cross the medial moraine and follow directly on the glacier.
Now you can see the North-West face of Petit Jorasses.
Before the glacier becomes steeper you can see the Refuge de Leschaux on the left.
You can reach the base of the face in 5 hours from Montenvers.
