Basalt organs at the Cascade du Déroc. On the Aubrac lake route Aubrac is a volcanic massif 5 to 9 million years old. Its highest point is the Signal de Mailhebiau (1469 meters).
It is bordered by rivers: the Lot to the south, the Truyère to the north and the Colagne to the east. The plateau is made up of a variety of rocks. On the foothills of the plateau, near the Lot valley, we find a lot of gneiss and schist. In the center, basalt, a reminder of the area’s volcanic origins, is omnipresent.

Le Signal de Mailhebiau, in spring.The creation of the basaltic part of the plateau is the result of an effusive volcanic episode (with lava flows). Traces of this ancient volcanic activity abound here, with basaltic organs sometimes appearing in unexpected places.
Among the most impressive are waterfalls such as Déroc and Saltou.
Granitic rock on AubracDID YOU KNOW?
To the north and east of the plateau, the landscape resembles that of the Margeride, with large granite boulders scattered here and there across the plateau.
The granitic and basalticsections bear traces of the three successive ice ages:
Stream on the Aubrac.In the foothills of Aubrac, the landscape contrasts with the great bare expanses of the plateau to the north.
Covered mainly by mysterious beech forests, this is the land of the boraldes, the streams that meander through the deep valleys to flow into the Lot.
Basalt organs and erratic boulders can be found mainly at Cascade du Déroc
Located in the south of France, in the Occitanie region, the Cascade du Déroc is on the Aubrac plateau.
