View of the Grandes Jorasses
Highlight • Viewpoint
The Grandes Jorasses, a grandiose mountain range in the Mont Blanc massif, casts its imposing silhouette against the sky. The rugged peaks, adorned with snow and ice, create a dramatic contrast against the azure canvas above. The play of light and shadow enhances the jagged edges, giving the Jorasses an almost ethereal quality.

Trail Reviews
From the bus stop (Bonatti refuge), climb through the woods for about an hour to the Bonatti refuge. Continue for two and a half hours at altitude, with some ups and downs, to the Bertone refuge. The views are beautiful, and the route is mostly sunny. From the Bertone refuge, descend through the woods to Courmayeur in about an hour and a half. The trail is well-trodden but quite steep. Total distance: 13 km.
Tour with spectacular views over the entire Mont Blanc group and the Grand Jorasses. After the descent from the Bonatti refuge and arriving at the Val Ferret road, you can take the shuttle bus to return to Entreves and close the loop
