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.
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".
