The valley's foundation is filled with alluvial fans and in the southern reaches it is partly swampy.

The northern slopes of Kamarska Valley on the Balkan Mountains are generally deforested and heavily eroded, while the southern slopes on Sredna Gora are covered with beech and hornbeam forests.

[1] The valley is located in Sofia Province, on the territory of Gorna Malina Municipality.
