Graubünden - this canton of Switzerland is completely located in the Alps and is therefore first-class suitable for active vacationers. In winter, the ski slopes around Diavolezza and Corvatsch are very busy. In St. Moritz the high society meets for winter sports. Summer belongs to hikers and mountain bikers with green valleys and clear mountain lakes where you might even meet ibex. Rustic mountain villages are home to hearty hotels. A ride on the red Rhaetian Railway is not to be missed: It goes over narrow bridges at dizzying heights.
