Description
The Roches de Borée are like a set of phonolitic domes exposed by erosion. Similar to the surrounding peaks (the Pialoux rock, the Gouleïou, the Touron peak), they bear witness to volcanism where the craters remain invisible.
These are typical examples of viscous lava needles that were deposited almost in a solid state. Here, no craters, but massive shapes in the landscape.
These multiple pistons are installed, like most nearby volcanoes, in a period ranging from 8 to 6 million years. Access via the car park on the village square. 1 hour hike (round trip) between the two rocks of Borée, 2 km (easy path). Follow the signs for the Montagne Ardéchoise. Interpretation table between the two rocks.
