The topography of La Celle-sous-Gouzon is defined by gently undulating hills and shallow valleys, with an elevation that ranges from a low of roughly 374 meters to a high point of 462 meters above sea level.
The commune rests on the granitic bedrock that is highly characteristic of the Creuse department. This geological foundation yields acidic soils that are better suited to grazing pastures and hardy woodlands than to intensive crop agriculture. The terrain poses few natural barriers, creating a sweeping, open feeling across the landscape.
