Access: From Briançon, head towards Villar-Saint-Pancrace.
At the entrance to the village, after passing the roundabout, take the D136A or Rue du Mélézin.
Pass the cemetery and turn left onto Rue de la Ribourelle (a dead-end road), then follow its continuation, which becomes Rue de la Croix de Bretagne.
Go to the end of this dead-end road where you will find a car park.
(S/E) Follow the lane (starting north-north-east) for about 500m until you reach a junction where two signs point towards La Croix de Bretagne.
(1) Take the left-hand path heading east (yellow sign); the military road on the right is reserved for the return journey.
(2) A little further on (about 300m), at the Y-junction, take the path on the right which climbs through the larch forest towards the Croix de Bretagne (yellow sign).
(3) Shortly afterwards, at a bend, turn right onto a path and continue along it for several kilometres, carefully following the direction indicated by the yellow signs, then head for the Fort de la Croix de Bretagne.
(4) Walk along the south side of the fort towards the west to reach the military road linking the forts, which is simply a wide stony track.
(5) Take this path to the left (south-south-west) and follow it up to Fort de la Grande Maye.
(6) For the return journey, head back down in the opposite direction to the Croix de Bretagne crossroads.
(5) Turn left onto the military road until you reach the junction you passed on the way up.
(1) Head down to the left along the route you took on the way there until you reach the car park (S/E).
