Park in the car park near the bridge over the Save (right bank), 50 metres west of the bridge on the D9.
(S/E) Leave the path heading south and take the wide path that turns west, then after a left turn, climbs quite steeply for about 600m. After a few bends, you will arrive on the plateau. Continue straight on the dirt track until you reach the small asphalt road lined with houses in the woods, Chemin de Bacuran.
(1) After travelling about 400 metres along Chemin de Bacuran, you will see a firebreak on the left with a power line running down the middle. Take this direction, following a path that is not very visible as it is not maintained for a short distance. Continue along a wide, clean grassy path, passing fields on your left and, further on, the sports field on your right, until you reach a crossroads with four paths.
If you are unsure about the poorly maintained section, you can continue along the road towards the D69c and, about a hundred metres before it, take the wide path that descends to the left.
(2) Turn left onto the wide path and follow it to the picnic area on the D9g. This road also follows theGR®86 trail, marked in red and white.
(3) At the picnic area (D9g), continue right on the road until the second intersection.
(4) At the intersection, turn left onto the D9d towards Villa gallo-romaine, continue straight ahead, cross the bridge over the Save and continue to the right-hand bend.
(5) At the bend in the road, turn left and take the dirt track towards Chemin de Quaillavemes,GR®86,PR®9. Follow this track to Sarremezan, running alongside the Montégut stream.
(6) In Sarremezan, when you reach the crossroads behind the statue of the Virgin Mary, turn left onto the road. After about 150 metres, leave theGR® and turn left onto the D98b towards Lespugue. Stop at the Saint-Julien Chapel, go around it and continue on the D98b to the hamlet of La Hazeuille.
(7) Cross the hamlet of La Hazeuille. To enjoy the view on the left, it is advisable not to take the street on the right immediately, but to continue to the fork at the exit of the village where the D98b meets the D98. At this point, turn right then left and continue for about 200 metres until you come to a developed area on the right at the entrance to a farm with a "funny" mill and a small bridge.
(8) Turn left with your back to the mill onto the small road that goes uphill. Continue until you reach a four-way intersection. Turn left onto the dirt road and stay on it until you reach Lespuge on the right-hand side of the bridge marking the exit of the village.
(9) Turn right and then immediately left, cross the village and head towards Blajan (D98).
(10) Make a round trip to Lespugue Castle. You can visit the ruins, but:
Caution: as the top of the ruins is unsafe, do not get too close to the cliff edge and remain very cautious as there is a risk of falling.
Back on the road (D98), turn left and continue to the D9.
At the intersection with this road, turn left. Caution: there is a lot of traffic, so be careful. Cross the bridge over the Save and return to the car park (S/E).
