The Engadin or Engadine is a long valley in the Swiss Alps located in the canton of Graubünden in southeast Switzerland. It follows the route of the Inn River from its headwaters at Maloja Pass running northeast until the Inn flows into Austria, one hundred kilometers downstream. The Engadin is protected by high mountains on all sides and is famous for its sunny climate, beautiful landscapes, and outdoor activities.The Engadin is divided into two parts:
The Upper Engadin from Maloja to Zernez, where the valley is remarkably straight and wide, and up to S-chanf, fairly flat
The Lower Engadine from Zernez to the Austrian border, where the Inn drops more quickly and its path is more tortuous
