Be careful not to confuse things! Unlike the recent volcanism of Salagou (around 1.5 million and 750,000 years ago), the reliefs stretching out before you are the remnants of an ancient mountain range formed nearly 400 million years ago (Hercynian orogeny). Then, hundreds of millions of years of erosion shaped the landscape you admire today.

At the turn of the relief, the lake of the Olivettes appears like a breath of fresh air in the landscapes of the Avant-Monts. The reservoir is set in a jewel box of limestone hills, where the lines of Pioch Perdut and Roc de Castel Viel structure the horizon.

This superb route is extremely exotic. It crosses the Salagou Valley and takes you straight to the characteristic ochre trails around Lake Salagou.

Several roads converge on the Col de la Merquière, a delight for cyclists. Especially since one of them leads straight to the Salagou Valley.

Good loop up to this point. Unrideable section here - but alternative route available 😅
