Park next to Clermont-le-Fort Town Hall.
(S/E) Opposite the monumental gate, next to the town hall, take the botanical trail which descends steeply and is slippery in wet weather. At the intersection, leave the trail on the right which descends towards the hamlet of Les Fraysses and continue straight ahead to reach the place known as Rive d'Aïgue. Cross the road and go back up to take the path lined with a hedge on the right.
(1) Follow the path to a road. Cross it and, going downhill, take the private path on the left. Continue for a few metres and turn right onto a path in the undergrowth that follows the Notre Dame des Bois stream in the Infernet valley. Go up to the right to leave the woods. Continue until you reach the Notre-Dame-des-Bois Oratory.
(2) Continue along the path. At the top of the hill, pass a farm and continue to the main road. Turn left and take the D 94 main road. At the crossroads, take the road opposite that goes up to the water tower.
(3) At the top, turn left at the house. The path follows the ridge. At the end of the path, opposite the Lambert farm, turn left until you reach the junction with the D 68 departmental road. Turn onto the gravel path opposite and follow it to the junction with the D 35 road. Turn opposite and go around Le Marsal farm on the left, then continue along the hedge to the junction with the D 68e road.
(4) Turn left. At a place called Les Oustalets, follow the left-hand lane and then continue along the main road to the left. At the top of the hill, turn left onto the gravel path lined with a hedge, towards the Cabanes farm (visit and snack at the farm). At the end of the path, turn right. At the bottom of the valley, turn right onto the path that goes up along the hedge. Cross the D 68e road, cross the ditch on the sleepers and take the path that runs along the hedge. On the road, turn left then right onto a grassy track that runs alongside a property. The path follows the ridge (opposite the castle mound). The track begins to descend to a crossroads.
(5) Follow the track that turns right and take the road that descends to the left until you reach the junction with the D 68e road.
(6) Turn onto the small road opposite that leads to the hamlet of Les Fraysses. In the hamlet, turn right and then left onto the path that leads to the banks of the Ariège. Walk upstream (ferry boat) and follow the botanical trail along a steep path. At the crossroads, turn left to reach the car park at Fort-de-Clermont town hall (S/E).
