An extensive range of hills and mountains situated near to the Ukrainian border. Deep valleys traverse the IBA, which includes numerous scattered rock features such as boulders, rock stacks and inland cliffs. Fagus, Carpinus and Acer forest cover the centre of the IBA, with Picea on higher ground and Quercus at lower altitudes. Mesophile meadows occur on north- and east-facing slopes, whereas warmer south- and west-facing slopes support bushes, vineyards and arable land. Part of the IBA (less than 5%) is a military training zone and is closed to the public.
An important site for forest species, especially forest-nesting raptors. Ciconia nigra, Bubo bubo and Caprimulgus europaeus also breed. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex.
