ITINERARY
From Bourg-d'Oisans, head for "Briançon / Les 2 Alpes" on the D1091 as far as the Chambon dam. You'll pass through 4 lighted tunnels on this stretch; for your own safety, make sure you're visible.
At the dam, continue towards "Briançon / La Grave" (more tunnels await you).
At La Grave, drive through the village and pass through the "Serre du Coin" tunnel. Immediately after exiting the tunnel, turn right towards "Ventelon / Les Terrasses / Les Hières". You climb up above La Grave on a small balcony road facing La Meije.
When you reach Ventelon, turn right in the direction of Les Hières. At the end of the road, make a U-turn and continue towards Les Terrasses, then Le Chazelet.
If La Grave and its hamlets hold no more secrets for you, you can take the same road back down to Bourg d'Oisans.
