(S/E) From the back of the car park, head up Chemin de la Badio and take the path on the left marked “Route du Causse”. Climb gently through woodland and pastures towards the Causse plateau. After passing through the last gate, you will reach the information board for the Karst Trail.
Bat signpost
(1) Head straight towards the wooden signpost and turn right to reach the orientation table near the picnic table. Continue along the path through the pine trees to reach the Roc de la Fendeille.
(2) Turn back, taking the path that runs alongside the quarry fence. Pass the orientation table again, then head to thefirst wooden post. Turn right towards the large pine tree near the fence and follow this path down to the Chemin de Pistre. Take the very narrow path almost directly opposite and slightly to the left through the undergrowth. Walk past the Maple Doline to reach post no. 6: Grotte du Calel.
(3) Continue straight on along this path through short grass. Pass the Grotte des Gours and then marker post no. 8 to reach a T-junction with the Chemin de Pistre.
(4) Turn right and continue for about 150 m.
(5) Leave the Chemin de la Duretié (yellow markings) on your left; you will take this later to head back down towards Sorèze. Continue straight on until you reach the gate.
(6) Slip through the gap in the wire fence to the right of the barrier. Follow this path down for about 150 m and turn right at the wooden post. Walk past the burial cave. Enter the undergrowth and follow the stream until it disappears. This dangerous area is protected by a barbed-wire fence. Follow this fence to the wooden post.
(7) Turn left and head down towards the Aven de Polyphème. Return to the post and continue to the left. Pass in front of Les Buses, continue to your left and head back up this path. Leave the woods and return to the causse. Once at the top, you will cross the path you took earlier just before post no. 6.
(3) Turn right towards signpost no. 6. Turn left immediately and join the Chemin de Pistre in front of the fence.
(8) Turn right and continue for just over 400 m to reach the junction with the path coming from the Gours and Calel caves.
