The longest river in Europe is the Volga River. Flowing through central Russia, the Volga stretches for approximately 2,294 miles (3,690 kilometers) from its source near the Valdai Hills to its mouth at the Caspian Sea. It plays a crucial role in the geography, economy, and culture of Russia, serving as a vital waterway for transportation, irrigation, and fishing. The Volga basin also supports diverse ecosystems and is home to various species of plants and animals. Notably, the river is deeply woven into Russian history and identity, often hailed as the "Mother Volga" in literature and folk songs.
