Park in the car park at the Jastres oppidum.
(S/E) Walk about 150m towards Lussas to find the hiking sign and turn sharply left towards Saint-Laurent-sous-Coiron.
(1) Turn right (signposted). At the next three-way junction, keep right and at the next one, under the power line, turn left. Walk on relatively level ground to reach the wide path overlooking the Louyre gorges.
(2) Follow this path to a wide esplanade crossroads with an information board.
(3) Keep left on the wide path and continue straight ahead.
(4) Cross a first road near a cross and continue straight ahead. You will arrive at the Saint-Laurent-sous-Coiron road at a slightly complicated crossroads where you continue straight ahead.
(5) Begin the long climb up the road (there isn't much else) towards Saint-Laurent. The view at the top is well worth the effort.
(6) Just below the village, before the Auches farm, at a transformer, a path on the right allows you to cut across a long hairpin bend. Climb up the narrow streets to the castle (ruins).
(7) Descend via a small path south of the castle, then down to the church and around the village to rejoin the arrival route. Descend to the left.
(6) Turn left to reach the junction with the Saint-Laurent road.
(5) Then take the D324 on the left heading east and then south.
(8) Leave the road when it turns left and continue straight ahead along the vineyard path. Continue straight ahead to the hamlet of Maisonneuve. Turn right in front of a large building and continue straight ahead at the next junction to reach a new crossroads.
(9) Turn left. Ignore the road to Comdamines and keep right at the next three-way junction. After about 50 metres, continue straight ahead on the wide road heading south-west.
(10) Before Eyriac, turn right onto Chemin des Renges, then left onto Chemin des Combasses. Before reaching the junction with the D259, and to avoid a very busy area, take the first street on the right to enter Eyriac.
(11) At the junction with the D259, turn briefly left then right (signposted). Follow the road almost due south to Les Rieux, passing under a power line.
(12) Turn briefly left then right towards Mias. Keep right at the next crossroads.
(13) In Mias, turn right, look for the "Dolmen" sign on the left, pass between the houses and follow the path, still heading south-west, to the dolmen (see below).
(14) Then return to the village of Mias.
(13) Continue along the road on the left heading north-west. At the bend, turn left and follow the wide path uphill, which curves northwards, ignoring the turnings on the left. Continue almost due north to reach the D259.
(15) Follow this road to the left to reach the car park (S/E).
