Park in the small car park behind the church.
(S/E) Head west up Rue des Jardins towards the school.
(1) At the school, turn right onto Chemin des Pèlerins, which descends to the bottom of the valley and crosses the Ruisseau le Peyre stream before climbing back up to a tarmac road.
(2) Turn left onto Chemin de Barut, a ridge road offering views of the Ariège peaks in some places. Stay on this road, ignoring the yellow markings that invite you to turn left to reach the Barut farm. A few hundred metres further on, ignore the path opposite that leads to the Blazy farm and stay on the road, veering slightly to the right.
(3) At the T-junction, opposite the beautiful Régine residence, turn left onto Chemin de Castelnau. Ignore the roads that branch off to the left and then to the right and continue along Chemin des Moussats.
(4) At the bottom of the valley, just after the bridge, take the dirt track that climbs up to the left and turns right at the top.
Follow it to the junction with the Pouy de Touges road - D626b.
(5) Continue straight ahead on Chemin de Gratens, another tarmac road that descends into the woods before climbing again after crossing the Riou Tarac. A lake is visible on the left and you will reach Chemin de Monrous, which branches off to the left.
(6) Continue straight ahead until the next junction. You will see a second lake on your left and the Pyrenees opposite.
(7) Turn left onto Chemin d'Aurheillan and, at the next junction, left again (Chemin d'Argelès) and follow this road to the junction in the valley near a pond.
(8) Turn left and continue straight ahead until you reach the junction with the C4. Turn left until you reach a fork at a place called Danis.
(9) Follow the left-hand lane for 30 metres, then turn right onto Chemin de Biros. This tarmac road runs alongside a wood, passes below the village of Marignac-Lasclares, whose bell tower can be seen, approaches the Canal de Saint Martory and climbs to join Gratens via Chemin de Jouandas. Continue straight ahead, passing the beautiful town hall on your right, then at the foot of the water tower, rejoin the route you took earlier.
(1) Turn right to return to the church and the car park where you started (S/E).
