The Prättigau is a geographical region in the canton of Grisons , Switzerland . It consists of the main valley of the river Landquart and the valleys of its side-rivers and creeks. Landquart River, which drains into the Alpine Rhine in the town of the same name, is on its upper end home to the ski resorts of Klosters .

Landquart is a village with a railway junction on the flat floor valley of the Alpine Rhine just north of Chur , the capital of the Grisons.

The Prättigau is a tourist destination for winter and summer activities, including downhill and cross-country skiing, tobogganing and hiking.

Traditionally, towns in the Prättigau were reliant on the lumber industry, although the income from tourism has largely replaced that.
