The Durzon Spring - Canalettes
The Durzon resurgence and the Mousterian (Paleolithic) settlement are the unmissable highlights of this grand loop, which begins in a bucolic setting and continues along steep paths, among mossy rocks, to the Canalettes forest house. The return journey is via the descent of the Pas de la Mule, just as steep as the ascent.

Source du Durzon - SandrinePerego
GeologyThe Durzon Spring
Located at the foot of the Larzac Causse, in the south-west of Nant, the Durzon Spring is a karstic resurgence whose supplying basin extends over 100km² between L'Hospitalet du Larzac, Le Caylar, Cazejourdes and Egalières. The Karstic system doesn't retains water on surface and constitutes big undergroung water reserves.
The flow of the source varies between 0,8m3/s and 35m3/s and has an average temperature of 11,13°C. The Durzon river runs for 6km and flows into the Dourbie river at the place "La Mouline".
Description
ROUTE CLOSED DUE TO WORKS FROM 18 MAY 2026 TO 30 JUNE 2026
- From the parking area, take the road to the left towards Mas du Pré and cross the pretty bridge (you can see the hamlet on the left). At the iron cross, turn right and follow a fairly wide dirt track that runs alongside meadows and fields. The track then narrows as it enters the woods. The Durzon River is very close. At the intersection, leave the small tuff bridge on the right (private property of Victor Hugo's descendants) and turn left.
- 200 meters further on, at a fork in the path, take the right-hand path and continue for about 800 meters to reach the spring.
- Continue straight ahead (it is possible to cross the Durzon on the concrete footbridge and take the small path on the left to go around the expanse of water and rejoin the path that climbs above the spring). The climb, quite steep, is through woods and over rocks for about 500 meters. Once on the plateau, continue along the path for about 1 km until you reach a wide track on the right.
- Make the short round trip (200 m) to the Mousterian shelter, then continue on the path that branches off to the right to reach the Canalettes forest house. At the junction with the track, follow it to the left towards La Blaquèrerie for 300 m.
- Leave the track by taking the grassy path on the left towards the Pas de la Mule. After 500 m, turn sharply left and continue downhill on the track for 600 m through the forest.
- Turn right onto a narrow path at a concrete marker inscribed with the number 21. The path winds its way down before beginning the descent between the rocks. Pass the Pas de la Mule and continue to rejoin the path along the Durzon river. Take the path on the right, the same one you took on the way up, to return to the starting point.
Recommendations:
Fairly steep climb between point 3 and point 4. Difficult but short section at Pas de la Mule.
