Ray Pic Waterfalls
Experience the Ray Pic waterfalls where water from La Bourges river bursts through basalt rock. This natural volcanic site has been listed since 1931.
Basalt flow from the Strombolian volcano of Gravenne Thueyts. It reaches locally more than 50 m thick and 80 m high, so it is one of the largest of the Young Volcanoes of Ardèche and one of the highest in Europe.
This staircase consists of volcanic stones is located in a natural fault in the basaltic flow of the Causeway Giants. It also allows you to join the village of Thueyts up the climb from the Devil’s Bridge.
Gravenne of Thueyts
Strombolian volcano (Gravenne), attached to the young volcanoes of Ardèche, the Gravenne de Thueyts is a Strombolian type volcano erupting crater culminating at 600 m. altitude.

The Prades coalfield and its mines
The Prades coalfield and its mines form a kind of parallelogram, two kilometers wide, lying about ten kilometers from north-east to south-west, around the communes of Lalevade d’Ardèche and Prades.
The Pont de Labeaume site, virtually where three valleys join, presents a major geological attraction in a small area: the morphology of the valleys is easy to understand by the superposition of basaltic flows.
The hell’s mouth waterfall
The waterfall of the “Gueule de l’enfer” = Mouth of Hell is fed by the brook Merdaric in the town of Thueyts. It is ephemeral and is visible only during heavy rains. You can observe it along the hiking trail that leads to Devil’s Bridge.
This is the largest volcanic bomb in the region of the Young Volcanoes of the Ardèche. This bomb (the lip of the Souilhol volcano crater) has a vaguely tapering aspect and probably weighs seven to ten tons.
Bowl of Jaujac volcano
The name of the Bowl of Jaujac is due to its shape which apparently looks like a drinking bowl. “It is one of the most regular Volcanoes in France, even the most perfect” (Brousse & Berger, 1967, p.3).
These 215 steps stairs cut in the volcanic rock will lead you to the plain of the Vernède, it also allows you to reach the old abandonned village called Fargebelle before descending to the natural site of the Pont du diable.
The holed rock
The holed Rock, “Lou Ron Trooutcha” in Ardèche dialect is a geological feature located in the town of Mayres. The rock is so called because it has a skylight formed in a pile of stones.
Created by « les amis de Lafarre » association, the botanical trail invites you to the discovery of local flora.The signage presents you the specificity of the plants and trees.
Faysses du moulinage of Chirols
While until then, the faysses had always been occupied by vines, fruit trees or market garden plants …
The Chambon’s maar
The maar (volcanic explosion crater) of Chambon cut into the base to extract stones cut for the construction of some houses of the village.
Geological curiosity, the Pourcheyrolles waterfall was born from a volcano. It springs from a basaltic flow 32 m high overlooking the Fontaulière.
Visible from the belvedere Pourcheyrolles bordering the RD 536.
The “suc” of Bauzon, volcanic cone
The “suc” of Bauzon, typical strombolian volcanic cone culminates at 1471 m and its crater measures nearly 430 meters in diameter. Its flow, locally thick of 30 to 40 m, was released in the bed of the Loire on 8 km.
This small lake of maar (volcanic explosion crater) is located just west of the Maar of la Vestide du Pal. It was filled with runoff water. This lake is located on private property, so it is not accessible to visitors.
Mofette de gaz carbonique
A mofetta is a carbonic gas emanation from lava cooling below the earth. Very spectacular, there are only 3 in Europe: the dog cave in Pouzzoles near Naples, Royat (Puy de Dome) and Neyrac.
The féraou gours
The Féraou Gour is located in the hamlet of Conges, it forms a natural pot at the foot of a waterfall.
A famous columnar blue basalt flow forming prisms. On the banks of the Lignon, this gigantic flow seems to want to submerge us, creating impressive gorges looking like organ pipes. It is said to be the most beautiful in Europe.
The volcanoes in the commune of Meyras are part of the Young Volcanoes of Ardèche. The Souilhol volcano and its two flows as well as the Maar Doris were thrown up during the last eruptive episode affecting the Bas Vivarais.
The coal mines
The coalfield called Prades, a close-up of two kilometers, a distance of north-southwest, around the municipalities of Lalevade d’Ardeche and Prades.
Abraham rock is a highest 1 498 metres of altitude peak. Abraham rock, ancient occitan name « La Ranc Abran », « The steep rock ». It forms the highest of Barnas and La Souche towns, the summit is situated at the boundary of these two locality and of Mayres.
