Narbonne towards Gruissan. At the large roundabout at the entrance to Gruissan, located at the foot of the lake, take the D332 towards Narbonne Plage. 200 m further on, turn right (to turn left safely) towards Chapelle des Auzils. The car park is 1250 m further on, on the left, marked by a fire hazard sign and a small wooden sign saying "Gruissan climbing site...Les Caunes..."
(S/E) From the left of the car park, at the foot of the wooden sign, head north-west, bearing 320° towards a scree slope.
(1) Just before the scree slope, take the path on the left towards the climbing cliff. Climb up and follow the cliff for about 150 m, passing in front of cave G1, which is strangely often overlooked. If you see a small cave 15 m above you, you have gone too far. Visit G1 and then retrace your steps.
(1) Before the path that leads back to the car park, climb up as if to go around the cliff. This is the path used by climbers to get between the top and bottom of the cliff. Climb to the top.
(2) Take the path on the left and reach the next crossroads.
(3) Turn left again, ignoring the paths to the right that run along the cliff, and follow the path for 400 m to a pretty hunting post.
(4) At this point, a fault line descends from the ridge. Descend to the foot of the cliff. At the foot of the cliff, continue to the right and follow the cliff for 400 m, passing in front of the G2 cave. At the sign saying "No climbing and danger of walking along the cliff", descend to the path 80 m below.
(5) When you reach the bottom, turn right and continue straight ahead until you see the Grotte de la Crouzade cave on the heights to your right.
(6) Leave the path that leads up to it (you will take this on the way back) and continue straight ahead until you reach the small Gorge du Rec, secured by a chain.
(7) At the end of the safety chain, take the path that climbs up to the left, almost making a U-turn. Follow this path and, after about 300 m, ignore a path leading off to the right. Continue straight ahead along the cliff for 300 m until you reach a colourful hunting post.
(8) Continue for another 50 metres to see the tip of the cliff. There, turn right to rejoin the main path 50 metres away. Descend from the plateau by turning left and continue straight ahead (200 metres) to the ruins of a sheepfold. At the crossroads by the ruined sheepfold, take the path on the left for 400 metres, skirting the cliff at the bottom and always keeping to the left.
When the vineyard on the right is protected by a wire fence, you will come to a small pine tree clearing, then continue for 50 m to a path that seems to go uphill along a low wall.
(9) Take this path for a round trip to cave G3, if you wish (there is no clear path leading to the cave).
(9) On your return from the cave, continue straight ahead until you reach the bottom of the Combe du Rec. At the bottom, cross the stream until you find the path you took on the way there, which runs alongside the stream.
(5) Continue left on the path you took earlier, straight ahead until you see the Grotte de la Crouzade cave on the heights to your right.
(6) When you reach the foot of the large cave, climb up the scree to see it (entrance blocked). Leave the cave by heading left along the cliff, then climb up the scree, staying as close as possible to the cliff on your right. Pass in front of the small Crouzade cave.
Climb to the top, where, 2 m to the left, you may find a faint path leading east/southeast (towards the sea). In any case, continue straight ahead in this direction. After 100 m, you will arrive at the Gouffre de la Crouzade.
(10) Then continue straight towards the sea (invisible path) to find the path you took earlier that runs along the cliff, about 150 metres away.
(3) Take the path to the left, walk along the cliff for about 200 metres and you will reach a fork.
(2) Continue straight ahead and leave the route you have already taken, ignoring all the paths leading to the left.
(11) Towards the end of the cliff, at a fork, take the most marked path that descends to the right.
When you reach the bottom, immediately turn onto the path on the right. Do not take the path on the right or the road. Find this path 20 m above the path, which branches off to the right, parallel to the path (at the foot of an old scout teepee).
Only this path leads to an interesting ruin, which could be a drinking trough or thermal baths. Return to the centre, at the bottom of this ruin, and take the path that descends and leads just above the starting car park (S/E).
