Rastoke is the historic center of the Croatian municipality of Slunj. This old part of Slunj is known for its well-preserved mills and the picturesque little waterfalls along the Slunjčica river, which flows into the river Korana at this place. The Korana river originates at Plitvice Lakes National Park.
At Rastoke, similar natural phenomena are occurring as at the Plitvice Lakes. This location is therefore often being referred to as "the Small Lakes of Plitvice". Both locations are interconnected by the Korana river. Rastoke is a place of autochthonous ecologic and ethnographic significance due to its symbiosis of natural and civilizational features.
The town of Slunj emerged around Rastoke and the branching of the Slunjčica and Korana rivers. The watermills erected at this place largely contributed to the economic development of Slunj as the center of the region of Kordun.
