Mont Mouchet is a peak that is part of the Margeride massif. There, you'll find very rocky areas and other more wooded areas, composed of beech and fir forests. As a result, the landscapes are fabulous. Mont Mouchet is also a site classified as a High Place of the Resistance in Auvergne. From here, you can enjoy a superb 360° panorama.

Very nice hike, I recommend starting in the opposite direction in order to finish by going down the scree rather than going up... otherwise the hike is mainly on shaded paths...

It feels like Scotland, the nature is very green and the ruins of the castle make it a remarkable place.
