The car park will serve as the starting point; it is located at Haut Guards opposite the last junction for the leisure centre on Route des Guards.
(S/E) Head back down and take the road on the left at Saint-Rimbert until you reach the crossroads.
(1) Continue left on the path marked in yellow. You will see the Rocher de l'Aiguille on your left (which you can visit if you wish).
(2) Keep to the small path on your right, still marked in yellow, which climbs gently through the woods.
(3) At Les Blaches, turn left, and at the next fork (elevation 551), turn left again. Join another wider path on the Plateau des Cailles. Then climb a steeper, rocky and stony path. You will come to a fork (elevation 643).
(4) Admire the view from the top of Saint-Jaume, turn left and arrive at a crossroads (small pass), cross this pass and turn left onto the almost horizontal path until you reach a fork.
(5) Climb up the path on the right, heading south-east. I recommend staying on the main path as there are many other tracks. At elevation 804, continue left north-east and follow the ridge path to La Garde Grosse (elevation 944).
(6) Stay on the path to the right behind the antenna (you will be treated to some splendid views), then the path descends until it rejoins theGR®9at a multiple crossroads.
(7) Take it on your left, descend through the woods, cross a road and continue alongthe GR® for a short distance up a steep slope until you reach a wider path.
(8) Leave theGR® trail and turn left to rejoin the road at a viewpoint overlooking the town of Nyons.
(9) Follow the road downhill for 300 metres until you find a path (passable by vehicles) on your left, marked in yellow.
(10) Follow this path, which narrows to a trail and ends at a wide right-hand bend.
(11) Turn right, north, onto the last small downhill path to finally rejoin the road (elevation 494).
(12) Head straight ahead along the road that leads to your vehicle (S/E).
