Take the N94 road to Montgenèvre-Italy. When you reach the ramparts, park in the Champ de Mars pay car park.
(S/E) Enter the Vauban city via the Porte de Pignerol. Continue straight down the Grande Rue, known as "la Grande Gargouille".
(1) At the bottom of the street, on Place Médecin Général Blanchard, there is a beautiful view of the Schappe park and mountains, and you can visit the Maison du Parc des Écrins/Ski Museum free of charge.
Turn left onto Grande Gargouille and then onto Rue Aspirant Jan.
(2) At the end of the street, go through the Porte de la Durance and follow the path down to the Pont d'Asfeld. Superb view! Cross the bridge and follow the winding forest road to the bottom of the ramparts of the Fort des Trois Têtes.
(3) Leave the path on the right and continue around the ramparts of Fort des Trois Têtes on the left. You can see the other forts: Fort Dauphin on the left (towards Italy); Fort d'Anjou in the middle, Fort du Randouillet on the right (towards Gap). Arrive at the shooting range (military site).
(4) Take the path down towards the military buildings called "Communication Y".
(5) Shortly after "Communication Y", take the path in the forest on the right and leave the tarmac road that leads to the Fontchristiane district. Follow the clearly identifiable trail in the forest, even if it is not officially marked. There are numerous signs for "Briançon" and coloured markings on the trees. Descend to the Parc de la Schappe (also worth a visit).
(6) In the park, take the bridge over the Durance and go up the path through the woods to the bottom of the Cité Vauban.
Enter through the Porte d'Embrun and return to the starting point via the "Petite Gargouille" (Rue Mercerie, Rue du Commandant Carthian, La Collégiale, Rue du Temple) and exit through the Porte de Pignerol to reach the Champ de Mars pay car park (S/E).
