Park in the car park at Mervilla church.
(S/E) At the end of the car park, on the cemetery side, take the path downhill (GR®653) marked in red and white. You will soon reach a T-junction.
(1) Keep right on theGR® until you reach a paved path, the Chemin Moulin.
(2) Turn left for 300 m, then take a hairpin bend to the right to descend Chemin du Falcou.
50m further down, leave the tarmac and follow the path straight ahead, which enters the woods. At the bottom of the valley, you will reach a crossroads, the Campistron crossroads.
(3) Take the path on the left which crosses the Forgue stream and then starts to climb. Walk along the top of the hedge to avoid the muddy section and return to the path a little higher up. Follow this path which climbs gently to Rebigue. You will come out onto a road, the D95a, at the Fount Grando crossroads.
(4) Continue opposite on the stony path climbing up into the housing estate. This is Impasse de la Fount Grando, which continues as a path on the left at the edge of the field. When you reach a small road (D95a, Chemin de Rouzaud), follow it to the right for 150 metres.
(5) Turn left before the small cemetery and take a grassy path (on the right-hand side of the road, a small promontory offers a beautiful view of the Lauragais hills and the Pyrenees). At the bottom of a steep descent, the path first turns right, runs alongside the field for 100 metres and then turns left to climb steeply up to the ridge. Continue straight ahead to descend into the next valley and climb back up towards the D95.
(6) Follow it on the left until the next intersection, 300m further on (be careful, there is traffic and little room to walk). Take the road that climbs to the right for 250m. You will reach a crossroads between a road and a path before the hamlet of Dupuis.
(7) Here you have two options:
- shorten the route by taking the road on the left which leads back to the church in Mervilla (Chemin de Pechmirol),
- continue on the circuit (option shown on the map). To do this, leave the road and take the tarmac path on the right, which quickly becomes a trail along the edge of the houses.
This beautiful path winds down through the woods and comes out onto a tarmac road. Follow it to the right, continuing downhill. You will reach another crossroads with a path (not shown on the IGN map).
(8) Take this steeply descending path on the right. When you reach a road (Chemin de Savignol), turn left and follow it for 600 m. This is the start of the paved section of the route, which you must take to cross Castanet.
(9) Continue downhill to the left (Rue du Moulin de Courrège) and immediately turn left again, crossing the small square (Place Jean Galinié). At the end of this square, take the road downhill (Rue Bernard Janson), which leads to a stop sign on the D79. Follow the D79 to the left for 600 m, taking care of the traffic. Reach a three-way junction where the road begins to climb.
(10) Leave this road and take the paved path downhill to the left, Chemin de la Crabotte.
At the bottom of the valley, leave the tarmac and go straight ahead onto a steeply ascending path. It winds through the woods, comes out onto a meadow, then turns left to pass between hedges and arrives back on the D95.
Cross it and descend into the cul-de-sac opposite (Chemin du Moulin). 400m further on, take the grassy path on the right and continue to the first crossroads.
(1) Turn right, following the same route as on the way there, to climb back up to the church car park (S/E).
