(S/E) Leave the car park and head towards the roundabout. Before reaching it, cross the Route de Lias with caution (no pedestrian crossing) to take the D65, and continue towards the hamlet of Les Arramous.
(1) Leave the D65 and turn right towards the Grand Bois equestrian centre (Saint-Hubert). When the road ends, continue along the path that passes between the equestrian club's facilities. The path crosses the Grand Bois and, at the end of it, you will find yourself in the Gers. Continue along the path until you reach the tarmac road on Chemin de Grousset. Continue left on the road until you reach the junction with Chemin de Secouris.
(2) Turn left and climb gently towards the Lias radar station (la Boule Bleue). The road becomes increasingly rough, turning into a track as it crosses the Lartus woods, then becomes a road again at the edge of the woods.
(3) At the Pague junction, go straight ahead and climb towards the Chaü mill on the right-hand side of the road. La Boule Bleue begins to appear on the left; continue straight ahead to the foot of the tower topped with a blue radome concealing the civil aviation radar.
(4) Immediately afterwards, turn left onto the gas pipeline path.
(5) Follow the path into the woods opposite, while the main path descends to the right. After a while in the woods and a passage over the Crabères stream, rejoin the gas pipeline path in the open air and continue a little past the junction with the path leading to the Chaü mill.
(6) Take the path on the left into the woods and follow it until you reach the path leading to the mill. Shortly afterwards, the path bends: take the path on the right, cross the field and descend along the edge of the woods.
(7) The woods are L-shaped at this point: at the bottom of the L, take the path on the right that enters the woods. The path follows a stream and passes through relatively tall bamboo before emerging into the open air. The path continues uphill, following the edge of the woods on the left.
When the woods bend to the left, take the path on the right and follow the edge of the woods on the right-hand side until you reach the carriage road.
(8) Take this path and descend to the right. The descent is quite steep and the middle of the path is washed out when it rains. Descend until you see a gate on the left.
(9) Leave the path that continues downhill and take the shaded path on the right that leads to the D65 towards the hamlet of Les Arramous. Turn right and stay on the road until you reach the Haute-Garonne/Gers border.
(10) Leave the road and take the shaded path that leads to the Route de Lias after fording the Ruisseau des Crabères. Take the D37 on the left towards Fontenilles until you reach the entrance to the Lespèche industrial estate.
(11) Just before the industrial estate, take the shaded path on the right that runs along the outside of the first part of the industrial estate to the small stream at the end. Cross the stream using the carved steps and, at the top, turn left onto the path between the two parts of the industrial estate and head for the stadium car park (S/E).
