The start of the hike is located in the hamlet of Les Gourniers, accessible via the D241 road from the village of Réallon, not the Réallon ski resort, which is on the other side of the valley. Park in the car park just before the bridge over the Réallon torrent (toilet block).
(S/E) Cross the bridge and climb the tarmac road towards the 3 Cols Lodge. Continue climbing until you reach the Les Tomelles sign. Take the path that climbs to the right. You will come to a Y-shaped crossroads.
(1) Turn left, leaving the path on the right that leads to the Cabane du Vallon and the Col de la Coupa. You will reach the Les Usclas sign.
(2) Continue along the path that branches off to the right, making sure to follow the red dots marking the route. Otherwise, there is a risk of getting lost on paths created by passing herds. At the Les Clots sign, continue along the path. You will reach another fork.
(3) Leave the path and turn right, following the red dots to rejoin the old path (still on the IGN 1:25000 maps) which ran through the forest and is no longer used and difficult to find.
(4) Continue climbing along this path, still following the red dots. Pass below the Gardette hut.
(5) Continue south towards the Col de la Gardette, a distinct gap in the mountains that provides access to a valley where the Gap-Embrun road is located.
(6) Return via the same route to the car park where you started (S/E).
