 The Volga Region is almost entirely within the East European Plain, with a notable distinction contrasting the elevated western side featuring the Volga Upland, and the eastern side known as Transvolga (, Zavolzhye).The latter consists of the elevated High Transvolga and the lowland Low Transvolga.The Idel-Ural region, a collection of six federal subjects between the Volga River and the Ural Mountains, is generally considered as a part of the Volga Region, although the river does not run through each of them.
