Amongst European rivers, the Volga is in a class by itself. It's the longest river on the continent and also its largest by discharge volume. Its 3.5k km (almost 2.2k mi.) course lies entirely within Russia, and most of the country's major cities are on the river or its tributaries. In this drone video from Maksx, you'll get a great view of the river as it winds through Tolyatti, a mid-sized city which lies on one of the rivers great bends in its journey southwards towards the Caspian Sea.
