"Le Guilhaumard", it’s a karst plateau like no other, a Larzacian islet on the edge of the department of Hérault. Its specific geology and climate make it an eden for botanists. A real discovery!

Overlooking the Sorgues and Orb valleys, the Guilhaumard plateau features a characteristic landscape and relief, from dolines and caves, from ruiniform chaos to natural meadows. Following the itinerary, discover the resurgence of the Sorgues river as well as a wide range of remarkable flowers: pulsatile anemona, woodcock ophrys, Geneva bugle...


1 - From the walkers’ car park, cross the track and take in front a rocky path, then, a path that, further, goes down to the farm of les Aires. Take it on left on 200m.

2- Before the farm, turn right on the trail and go down to Sorgues.

The Sorgues resurgence is just before the hamlet on the left (go and back).

3 – Cross the hamlet and continue on the road on 2,5km. Turn left to La Mouline, pass over the Sorgues and then continue towards Saint-Rome-de-Berlières, on 800m.

4 - Turn on the left hairpin road, ford the stream and continue on the dirt track. Turn left on a path in the middle of boxwood and juniper, then follow the shaded path which climbs and arrives on the plateau at the “Pas de Tirecul”.

5 – On the plateau, (you can observe in spring and in the beginning of summer a lot of orchids), turn left and walk along the edge of the plateau  walking on tracks or old “caussenard” paths to join the Mas Raynal.
