Park at Place de la Mairie.
(S/E) Take Chemin du Lavoir to the right of the town hall. At the crossroads, turn right to reach the wash house. Turn back, ignore Chemin du Lavoir on the left, then turn right onto Route de Montesquieu and start climbing the hill until you reach the bend.
(1) Follow the path on the left indicated by a wooden sign. You will soon see the remains of the ancient road that probably linked Cazères to Montesquieu-Volvestre in Gallo-Roman times. The gradient is constant until you reach the tarmac road. Once you reach this road, join the crossroads with another tarmac road at "La Bourdasse".
(2) Continue left on the tarmac road to the hamlet of Béqui.
(3) Leave the road and turn left onto the path marked by the wooden sign "Gensac" and continue downhill along the castle hill. Reach the D62.
(4) Take the road on the left to return to Gensac. Turn right into the Mouzinatte housing estate and head for the banks of the Garonne. Turn left onto Chemin Saint-Pierre, which leads straight to Place de la Mairie (S/E).
