Car park at the Bois de Castres socio-cultural centre in Carbonne. The car park is on the other side of the Garonne towards Lézat (Route de Lacaugne).
(S/E) From the car park, take the path to the right of the bridge which descends rapidly towards the Garonne, then pass under the bridge and follow the Garonne. Follow this path which will take you to the heights opposite Carbonne with a pretty view of the Garonne and the village.
(1) Once you are back on the plateau just after passing under the power line, take the path on the right. "If you have reached the tarmac, you have gone too far; it is just after the electricity pylon."
after 200 metres, take the path on the left and follow the yellow markings.
(2) When you return to the road (Route de Latrape D73), follow this road to the right, continuing downhill
(3) When you reach the 90° bend on the right, take the path on the left at the corner of the bend, level with the safety barriers. Please note: do not take the path just before, it is just level with the barriers.
Further down, join the road and the bridge that crosses the Arize
(4) Once you have crossed the bridge, immediately take the path on the right to make a small detour and see where the Arize meets the Garonne (small beach). Continuing along the road, you will arrive at the main road between Rieux and Carbonne. Carefully turn right onto the D627 towards Carbonne.
(5) Once you have crossed the large bridge, take the path that descends to the banks of the Garonne just after the traffic lights, then follow the path along the Garonne
(6) At the end of this path, continue along the road that climbs towards the church. Once on the road, turn right and go down Rue Léo Lagrange towards the south
(7) At the end of this street, take the path that branches off to the right (go under a portico). You are now along the Garonne but on the other side from where you started the walk.
(8) At the end of this path, you will find yourself at the foot of the bridge. Go up Rue des Bains, then turn right and take the stairs to go back up onto the bridge. All you have to do now is cross it carefully and you will be back at the starting point (S/E).
