Park in the small shaded car park on the banks of the Garonne at the southern exit of St-Béat along the RN125, just after the bridge.
(S/E) Do not follow the N125 but turn right onto Rue du Faubourg, which forms part of theGR®86. At number 76, you can see two Garonne flood marks (including the one from June 2013) on the doorframe.
(1) At the end of the street, continue right uphill along Chemin de la Rouère.
(2) At the end of the path, near the hamlet of Ladivert, leave theGR®86, which climbs to the right, and take the path that descends steeply between the houses and the village road. At the bottom, after less than 100 metres of descent, turn right. Pass the cemetery and continue to the T-junction at the end of the road.
(3) Turn right onto the path that leads to the foot of the mountain, part of which has recently been gravelled. Veer left and negotiate two hairpin bends.
(4) Ignore the track on the left leading back to the D125 (cycle route) and head straight on to continue following the foot of the mountain, passing close to the hamlet of Millas in the commune of Arlos (drinking water fountain). On leaving the hamlet, continue along this path at the foot of the mountain.
(5) After a short climb, with the small waterfalls of the Ruisseau de la Batch on your left, rejoin theGR®10after crossing the stream via an arched bridge. Continue along the mountain-side path to reach the canal, then follow it to the right for 400 m.
(6) Cross the canal. Go round the roundabout on the left: be careful, there is no protected crossing at this point. Head towards the village of Fos, staying on theGR®10trail.
(7) Opposite the Chapelle du Batan, turn left onto the small road.
(8) At the wash house, take the footbridge on the left across the Garonne and continue slightly to the right for a few dozen metres along the street opposite.
(9) Turn left between the houses onto a path with pebble steps to reach the Chemin d'Argut above. Follow the tarmac road to the left until it ends at a cross (Christ d'Arrieuet)
(10) Turn right onto the path that climbs through the undergrowth, crosses the Rimbat stream via a hairpin bend and opens out onto a balcony overlooking the Garonne valley, before reaching Argut-dessous.
(11) At the fork in front of the town hall, continue by turning right-left-right-left through the village’s narrow streets to rejoin the path through the woodland.
(12) At the end of the descent and before reaching the RD44e, turn right onto the path which climbs steeply in places and is made very wet by a nearby spring. When you reach the first houses in Lez, head down towards the church and the cemetery, which you leave on your left, and cross the torrent via the bridge.
(13) Turn immediately left onto Rue Jeanne Couret and leave it behind, following the cycle path that runs under the road leading to the Saint-Béat tunnel. Follow the edge of the Argut road, passing in front of the secondary school
(14) At the crossroads, head straight on along Route de la Tignerie (follow the signs for the Tourist Office). Walk down to Place Galliéni, lined with lime trees. Make your way to the old bridge.
(15) Cross the Garonne via the bridge and turn left onto Avenue Galliéni (home to the Marshal’s birthplace), which runs through the village and its shops. On leaving the town centre, follow the Garonne and return to the starting point (S/E).
