The Kordun region is a part of central Croatia from the bottom of the Petrova Gora (Peter's mountain) mountain range, which extends along the rivers Korana and Slunjčica, and forms part of the border region to Bosnia and Herzegovina. The southern border of Kordun touches the Lika region. Most of Kordun with its centre Slunj belongs to Karlovac County ( Slunj, Cetingrad, Krnjak, Rakovica and Vojnić). Vrginmost belongs to Sisak-Moslavina County. In former times, this region belonged to the Habsburg Military Frontier towards the Ottoman Empire.
The area has rich wood resources. Today, the economic situation is slowly improving, but there is still a large tendency of emigration from the region to larger cities. A typical phenomenon of this region is the porous composition of the karst soil (consisting of limestone), which creates numerous crater-like dolines (sinkholes, Croatian dolina).
