 Dniester Hills run and ridge along the Dniester River, from the Colachin river, an affluent of the Prut river, and the Plonini Forest to the point where Dniester receives its tributary Răut.The river Dniester in turn bounds Dniester Hills to the N and E, and separates them from the Podolian Plateau.Dniester Hills are separated from the rest of the Moldavian Plateau (Suceava Plateau, Jijia Plain, Bălți steppe, Central Moldavian Plateau) by the passages formed in the valley of the Răut River and its tributaries, and partly by those of the Prut River and its tributaries.
