Tamins is a municipality in the Imboden region of the canton of Graubünden in Switzerland. It is located around 10 km west of Chur. Under the castle rock in the Reichenau district, the front and back Rhine join to form the Rhine. To the west of the Reichenau-Tamins train station in the Domat/Ems municipal area, the Rhaetian Railway line separates from Chur: one line leads via Thusis into the Engadine, the other via Disentis/Mustér to Andermatt. After crossing the Vorderrhein, this line lies in the Tamins area up to the height of the Wackenau ruins. The municipal area extends beyond the Kunkelspass to the north into the Tamina Valley. Above this area and the Grossalp there, the municipal area extends into the high mountains with the Ringelspitz as the highest point at over 3200 meters. The
