This Strombolian-type volcano (a truncated cone with a basin shape at the top) rises to 1175 metres, and stands facing another volcano, Mont Baury, with the village of Allègre on its slopes.
Mont Bar is unique in Europe, the only Strombolian-type volcano with a peat bog in its crater. The formation of peat was fostered by a drain dug in 1821 to dry the lake in the crater. Guided visits are organised to the Mont Bar site.
