Mons la Trivalle, Herault.

A beautiful walk from Mons (Mons la Trivalle). Up on the old blue triangular marked path that follows the stream up from the village then onto the red/yellow path. As the path bears left take the blue line marked route (it's not a path, just a scramble up the rocks of the stream that goes all the way up to the col above). This route passes some old mines but don't do this walk if you have difficulties with climbing). Return on the yellow then red/yellow route from the top that goes left. You can also return on the gorge side down the red route if you want a really tricky route.About 3 hours if you do the whole route. Or just go up and back for the beautiful views.
