Park near the Croix de Couzol at the Col de Magès.
(S/E) Take the path down towards the Gouffre de Cabouy: there are no signs, so continue on foot along the small road that brought you to the Col de Magès and head for the Cabouy resurgence.
(1) Take the path on the left, go round the small building, then head straight right to take the path that goes round the resurgence. Follow the left bank of the Ouysse. Reach Saint-Sauveur. At the next crossroads, turn right and go through the barrier to reach the Gouffre de Saint-Sauveur resurgence
(2) Continue along the path that goes round the resurgence, climb up and reach a natural arch, the remains of an underground passage that has now become exposed due to erosion. Shortly afterwards, enjoy a superb view looking down over the Ouysse, but take great care, especially with children.
(3) Set off again, passing back under the arch, and leave the access path on your left to reach a cave, from which the water that formed the arch a little further on once flowed. Do not go beyond the wire fence to preserve the peace and quiet of the bats that live there.
At the exit of the cave, climb immediately to the right (*) to join the path just above and turn right. Continue on to reach a viewpoint.
(*) You can bypass this short climb (4 metres) by heading back down towards the chasm and taking the path that climbs to the right once you’re back on level ground.
(4) Continue straight ahead and reach the junction with a wider track. Cross it, stay on the path and reach the D673.
(5) Turn right onto it and follow it for several hundred metres (take care). You will then rejoin theGR®64and 652 at a bend.
(6) Follow them to the right. Then cross the Ouysse via the bridge and follow the right bank of the Ouysse to reach the Moulin de la Peyre junction.
(7) Turn right, follow the Ouysse and reach the Moulin de Caoulet.
(8) Continue on; although it may seem surprising, the footpath passes under the mill’s porch, and if the door is closed, you must open it to get through. Then stay on this typical Causse footpath until you reach a junction with a wider track.
(9) Take this track straight ahead, then leave it at the next crossroads to return to the initial crossroads you passed on the way there, that of the Gouffre de Cabouy.
(1) Turn left to reach the Col de Magès car park (S/E).
