From Montréjeau, head towards Spain on the D825. When you reach a large roundabout, turn right onto the N125 towards Spain. You will come to traffic lights on this main road. Continue straight ahead along the railway line, then turn left onto the D26 towards Barbazan. Park in the centre (Grand Rue Saint-Michel) near the town hall. Parking spaces are available in Impasse Bourguet on the right before the bend that leads to the castle.
(S/E) Start from the town hall (on your left). Follow the road up to the castle for 50 metres. At the left-hand bend, turn right onto a well-marked path (Avenue du Château) which runs alongside a wall and heads due east. The path climbs for 150 metres before joining a small road. Turn left and continue for 10 metres until you reach a fork in the road.
(1) Turn right, heading due east along a small road (Chemin de Lapale) which quickly becomes a track. Red and white markings. Continue climbing. You will come to a very large oak tree and a bench. Head due south along this wide, uphill track. You are now on theGR®78and the Camino de Santiago. The track becomes narrower and passes through a narrow section, with a rock face on the left and a stone wall on the right. You will reach a fork in the track with three paths.
(2) Continue climbing straight ahead. Leave the adjacent tracks and paths.
Climb up this track, which widens again. The track turns left and heads due east, arriving at a large area with a fork in the tracks.
(3) You will arrive at a large, completely renovated and open building. Cross the summer pasture heading south-east. Continue climbing due east to reach the multiple crossroads at a place called Les Paloumères. Leave the track and path. Be careful, there are many tracks and paths in this area.
(4) Turn right, heading due south for 100 metres, then follow the track that branches off to the right, heading south-west. Leave all the adjacent tracks and paths. You will reach another crossroads.
(5) Head left, south-east, climbing up a wide path that is stony in places. Follow this wide, steep path. Leave all adjacent paths. You will arrive at the altitude of 941 m (Caube on the IGN map).
(6)The path no longer climbs. After 200 m, pass the Pas de l'Âne.
Do not descend. Stay on the track that remains on the hillside. Arrive at the large Refuge de Saint-Martin, which is open and clean.
(7) The track becomes passable by vehicle. The place is welcoming. A stop can be considered.
Now it's time to think about the return journey. Continue along this wide track, which is in very good condition. The track descends and reaches a fork at an altitude of 896 m.
(8) Turn left, heading due east, onto the wide track suitable for vehicles. After 300 m, you will reach another fork.
Remaining yellow markings
(9) Leave theGR®78on your right, which climbs towards Génos. End of the red and white markings.
Continue along the track, following the bend to the left. After 900 m, in a left-hand bend, ignore a track that branches off to the right. Remnants of yellow markings may help. You will reach a fork at altitude 787, near the Fontaine du Mouscatère.
(10) Leave the track and the path. Continue straight ahead. Continue along the track, which winds its way to a crossroads at altitude 784.
(11) Turn completely left, heading due west, uphill, along a small grassy track.
After 500 m, turn right, the small track turns north-east and continues uphill. Leave the adjacent tracks and paths. It then heads due north for 200 m to reach a fork in the tracks (altitude 859 m).
(12) Turn left, then head due west. You will arrive at a multiple crossroads at a place called Les Paloumères, which you already passed on the way there. This is the end of the yellow markings.
(4) Continue straight ahead and descend via the same path you took in the morning, returning to the red and white markings. Pass the crossroads with the building and arrive at the narrow section of the track you passed on the way there. End of the red and white markings.
(2) Before the stone wall, turn left and descend along a narrow path alongside the stone wall.
No markings. Descend this path through the forest to reach a new crossroads.
(13) Continue straight ahead on flat ground, along the fence, leaving the wide path that turns left. Reach the end of the road (Impasse de Gès), red and white markings, continue straight ahead.
(1) Turn left and descend along the wall via the same path you took on the way up (Avenue du Château), end of the red and white markings.
