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.
In the Upper Engadin, as a result of the influx of people related to tourism, the number of Romansch and Swiss-German speakers are about equal, and in the heavily touristed village of St. Moritz there are few Romansch speakers. In the Lower Engadin, Romansch is still the most widely spoken language, but almost all of the people also speak Swiss-German and Standard German as a second and third language. Most place signs in both the Upper and Lower Engadin show both languages, e.g. St. Moritz - San Murezzan, Sils - Segl, Celerina - Schlarigna.
