From Saint-Martin-Laguépie, take the road that runs alongside the Viaur and park your car in front of the Lagarde Viaur cemetery, which is on the right-hand side before the village sign.
(S) Follow this road, leaving the bridge over the Viaur on your left. You will soon come to a fork, which marks the entrance to the village.
(1) Do not go up towards the village but turn left onto the flat road. Follow the red and whiteGR® signs and the Moulin de Cayrou sign. The small road runs close to the river. Leave it at Moulin de Cayrou and continue straight ahead. After about 800 metres, the path turns 180° to the right, straightens out a little, turns left and leads to the buildings of La Baute Basse.
(2) Continue straight ahead. You will reach a small road at a 90° bend. Go straight ahead and continue to the hamlet of Cros, where several houses are being restored. The road ends and you will come to a fork where two paths begin.
(3) Take the path on the left. It descends towards the river and follows it to the La Vicasse bridge.
(4) Do not cross the bridge but continue straight on the D53, leaving the group of houses at La Vicasse on your right. Follow the road, ignoring the farm track on the left, which leads to Maraval, and further on, the path, still on the left, which leads to La Brègue.
(5) 50 metres after a 90° right-hand bend, follow the red and whiteGR® markings that branch off to the right uphill. The path climbs steeply, heading south-west, still fairly steeply uphill, then flattens out before joining the D53.
(6) Cross the road and continue on the path opposite.
(7) After about 800 metres, leave theGR® and take a narrower path on the right, which leads to the D53, near the three buildings in the hamlet of Lermet.
(8) Follow the road to the left until the first intersection, where you must turn right at a 90° angle. Continue along this small road, ignoring the access roads to Riols and Pégarié, until you reach a fork.
(9) Leave the road to Natouyri on your right and turn left. Follow the road to the group of houses at Hermitage.
(10) Do not take the road uphill to the right, but continue straight ahead. You will soon see the village of Lagarde Viaur. Enter the village. Take the time to have a look at the church overlooking the road on the right and you will quickly reach a crossroads.
(11) Turn left to descend towards the Viaur and return to the car, which you will soon see opposite.
