The Engadin or Engadine is a long high Alpine valley region in the eastern Swiss Alps in the canton of Graubünden in southeasternmost Switzerland with about 25,000 inhabitants. It follows the route of the Inn from its headwaters at Maloja Pass in the southwest running roughly northeast until the Inn flows into Austria, little less than one hundred kilometers downstream. The En/Inn subsequently flows at Passau into the Danube, making it the only Swiss river to drain into the Black Sea. The Engadine is protected by high mountain ranges on all sides and is famous for its sunny climate, beautiful landscapes and outdoor activities.

The Grisons or Graubünden, more formally the Canton of the Grisons or the Canton of Graubünden, is one of the twenty-six cantons of Switzerland. It has eleven districts, and its capital is Chur. The German name of the canton, Graubünden, translates as the "Grey Leagues", referring to the canton's origin in three local alliances, the Three Leagues. The other native names also refer to the Grey League: Grischùn in Sutsilvan, Grischun in the other forms of Romansh, and Grigioni in Italian. Rhaetia is the Latin name for the area. The Alpine ibex is the canton's heraldic symbol.
