The Vals Valley (German: Valser Tal) is located in the canton of Graubünden in Switzerland.
The population is spread out across several hamlets and the village of Vals-Platz, which has an altitude of 1250 m. They form a Walser enclave, since the people in the adjacent Lumnezia speak Romansh.
Isolated finds show that the Vals Valley was used as a link between the Mesolcina and the Alpine Rhine Valley as early as the Bronze Age.
The lower part of the valley was settled in the 12th Century, if not earlier.
In the 14th century, the upper part of the valley was settled by the Walser migration.
