In Engadin, in the east the Piz Bernina – the only four-thousander among the eastern alps, the Upper Engadine lake plateau and the enchanting Engadine towns such as Sils, where Friedrich Nietzsche once stayed, in contrast to glamorous St. Moritz, the highest airport in Europe (Samedan) with numerous traditional activities.
The southern part of Graubunden stretches from San Bernardino to Grono, where it meets the Calanca Valley. Together with the Puschlav and Bergell valleys and the village of Bivio on the Julier Pass, the Calanca and the Misox valleys form part of the Italian-speaking area of the canton of Graubünden. Here walking enthusiasts will find countless paths and, in the Misox, the biggest forest reserve in Switzerland outside the national park (Val Cama and Val Leggia). The Lower Engadine with the town of Scuol at its centre and its Engadin Bad Scuol spa as well as the Münster Valley (Val Müstair) on the Italian border is the home of the only national park in Switzerland.
