GR®36red andwhite markings and yellow markings
(S/E) From the car park, head left towards the tunnel. Pass through the tunnel very carefully. Do the same along the narrow pavement. At the fork, go down the left-hand street to follow the Tarn, keeping it above you. The gravel path ends on the Route de Trébas, D77.
At the departmental road, take the hairpin bend to the right. Turn left at the first road, Route du Blasou. Ignore a service road going up to the right. Route du Blasou crosses a bridge and climbs up to a house.
(1) In front of the house, turn right onto the narrow path. The path climbs for about 800 m. At the crossroads, it descends back to the road, close to Vinçou on the right. At the road, move slightly to the left to continue on the road almost opposite. Walk alongside an abandoned vineyard.
(2) Turn onto the path that climbs to the left. This is the second climb to reach Puech Cabot, the first of the two puechs. The slope levels out as you approach the farm of the same name. There is a view of the valleys on either side of the grassy path. The priory of Ambialet and the relay pylon can be seen on the horizon. Reach the T-junction.
Yellow signpost
(3) Leave theGR®36, turning right, and follow the yellow markings. Ignore a path that branches off to the right. The road gives way to a wide dirt track. Pass between the small building and the entrance to the Borie Grande property. At a nearby fork (not shown on IGN maps), descend to the right onto the grassy path. Further on, the grass gives way to earth and stones. The path descends, makes a hairpin bend to the right and ends on the Alban road, D94.
(4) Cross the road. Head into the woods opposite. The wide dirt track winds and undulates until it reaches La Resse. There are signs indicating the direction to follow.
(5) Continue, leaving the Resse on your left. Very quickly, the path veers slightly to the left, facing a meadow. Follow the path along the wooded hedge. The path widens further on and crosses the woods before ending at the Route de Vinçou.
At the road, turn left and cross the bridge over the Ruisseau de Blasou. After the bridge, continue to the right. Continue along the slightly sloping road until you reach the farm track for Le Plô (letterbox at the side of the road).
(6) Take the path leading to the farm. After 100 metres, turn left onto the Impasse du Plô. The wide track winds gently uphill between chestnut trees, running parallel to the Route de Vinçou above. It ends at this road.
Cross it. Climb up the small path opposite to find the Route de Villefranche, D74. Cross it to rejoin theGR®36.

(7) Pass the calvary. Continue forward and turn right onto the dirt and gravel track. Climb gradually up to the relay pylon. This is the second puech on the circuit.
(8) In front of the entrance to the pylon, take the narrow, grassy path on the left. Covered with grass, it quickly becomes stony. This is a very steep and technical descent.
Halfway down, it is composed of stones and schist rocks.
A large rock provides a place to rest and enjoy the magnificent view of the Ambialet isthmus.
Further down, in front of the ruins of Château Saint-Raphaël, turn left.
At the end of the descent, a few steps lead to the D172. Cross the road with great caution.
Turn right to return to the car park (A/D).
