Built on the side of a cliff, Balazuc overlooks the valley of the Ardèche in a green setting. Its winding streets and Romanesque buildings take us back to medieval times. Balazuc is part of the "Most Beautiful Villages of France".
The stream of Sompe originates in the territory of the village of Lagorce. The Sompe is a tributary of the Salastre, which is, itself, a tributary Ibie. The course of these two streams is entirely in the Lagorce ban.
