Park on Place du Castella opposite the church, easy parking, in Laroque d'Olmes,
(S/E). Walk down Rue de l'Église, admiring the peaks of Monts d'Olmes and Montségur opposite, then turn immediately right onto the small square. There, take thefirst street downhill on the left, Rue Paul Vaillant Couturier, to reach the D620 towards La Bastide sur l'Hers more or less straight ahead. Follow Avenue Pierre Semard on the left for about 400 metres and leave the bridge over the Touyre.
(1) Turn right onto a small road that runs alongside the river and turns into a path at Guillouti.
Continue along the right bank until you reach some houses. Do not go up the Voie Verte for now, but stay to its right on a grassy track that opens up below to join the Entounadou crossroads and theGRP® Holmes.
(2) Turn left onto theGRP® and follow the yellow and red markings. Pass in front of the Grotte de Dreuilhe at the foot of a huge rock. You will rejoin the Touyre for a short while before passing under the Voie Verte. Then take the Voie Verte, which is the old railway line, and continue to the junction of the Voie Verte,GR® andPR® de Dreuilhe with a picnic area.
(3) Leave the Voie Verte and continue to the left to climb the Chemin de la Bouiche. At the start, only a mountain bike sign n°8 indicates the route, but very quickly theGR® de Pays markings take over. The climb is very steady on a wide track, sometimes paved with stones. Higher up, a sandy plateau in the middle of the forest allows you to enjoy the tranquillity of the place, just before reaching a nameless pass with no view.
(4) Begin a steady descent to discover the magnificent and peaceful Mérens, as well as a magnificent view just before arriving at the Ferme de La Bouyche.
(5) Descend the small road (Chemin de La Bouyche) which plunges steeply towards Ivry sur l'Hers to reach the road from La Bastide-sur-l'Hers to L'Aiguillon. Turn right onto the D16, then left across the Hers river and enter the hamlet of Camp Redon. At the exit, after the first houses, you will find a crossroads with a signpost:GR® de Pays –PR® –GR®7(Red and White) – VTT 8 and 9.
Turn left and climb the road to reach a new crossroads marked by a sign.
(6) Leave the road and turn left again to descend towards the Hers.
Pass a junction on the right, going backwards and uphill, without a sign: this is the GR®.
Continue straight ahead and follow the red and white markings that go around a huge rock and find a house near the river where a track starts. Follow it to reach the hamlet of Fontcirgue, formerly a renowned spa resort.
(7) Leave the bridge below on your left and continue straight ahead on the road. Pass a fishing promontory for people with reduced mobility and, shortly before the bridge, you will reach the La Bastide sur l'Hers picnic area, where there are two tables available.
(8) Cross the bridge and then the road junction to take the lane that opens up opposite the market hall on the right, clearly marked with a sign for mountain biking. Turn into thefirst street on the left, which offers a view of a small bridge on the greenway. Pass underneath it, turn immediately left but do not go up the greenway. Keep to the right to find the Route du Cimetière.
(9) Immediately turn right and climb up this small road, which turns into a grassy track a little further up. As you climb higher, the landscape opens up and the view becomes magnificent. Reach the pass on the D16 road.
(10) Take the path on the left, marked by a sign. Now walk along a magnificent, slightly uphill and steady wooded ridge. In the distance, you can see the first houses at the top of Laroque-d'Olmes. Above the rocks, a stone cross marks the location of the Saint-Roch Chapel.
(11) Take a short detour to visit this magnificent, secluded spot. Return to the path and continue downhill to pass through Porte d'Amont and return to the Castella car park (S/E).
