Located at Neyrac spa, this is an explosion crater. Volcanoes of this type happen when very hot magma at 1,200C° (lava) meets water several hundred meters below the earth.
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.
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.
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 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.
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.
Famous causeways and columns with blue basalt prisms. On the banks of the Lignon, this gigantic flow seems to want to drown us creating impressive gorges looking like organ pipes. It is said to be the most beautiful in Europe.
Faysses du moulinage of Chirols
While until then, the faysses had always been occupied by vines, fruit trees or market garden plants …
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.
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.

The Féraou Gour is located in the hamlet of Conges, it forms a natural pot at the foot of a waterfall.
The Verdier site located in the heart of the village of Burzet, this flow results from the Ray-Pic, one of the basalt flows of France richest in peridotite nodules. Very nice view of the Bridge.

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.
Granite sea or Clapas
Large field of granite stones at the foot of Mount Aigu mountain, on the North face. The clapas means a pile of rocky debris, the rocks gather together to form like a sea of granite.
