Most probably "Arieș" means "Gold River", the name being derived from the Latin "Aureus". The Hungarian name "Aranyos" means "Golden" and it was first mentioned in 1177.[2]



The source of the river is in the Bihor Mountains, part of the Apuseni Mountains, which translates as The Western Mountains. The Arieș is formed near the village of Mihoești at the confluence of two headwaters: Arieșul Mare and Arieșul Mic. It flows through Alba and Cluj Counties and flows into the Mureș near the village of Gura Arieșului, which is close to the town of Luduș.

The towns of Câmpeni, Baia de Arieș, Turda, and Câmpia Turzii lie on the river Arieș. The upper valley of the river, Țara Moților, is a beautiful rustic region and an important mining region (Roșia Montană), rich in gold, silver and uranium. Those mines of Apuseni Mountains (also known as "Metaliferi Mountains") were exploited since Dacian reign, and later on they attracted the Roman invasion.
