The Grand Tour of Switzerland includes thrilling bends and scenic views at every turn, and five of its famous alpine passes stand out—literally—among the rest of the route. They are engineering wonders that often overlook natural wonders as well. The Flüela Pass, which connects Davos and Susch, reaches a height of 7,818 feet. Your ascent through alpine forests delivers views of the valley below on a route that Avis ranked number 4 on its list of the “world’s best roads.” The Julier Pass is lined with picturesque lakes and ends at the village of Tiefencastel, with its historic, and equally picturesque, Church of St. Stefan. The San Bernardino Pass in southern Switzerland follows a route used since the 15th century and sits on the border between the country’s German and Italian regions. With its serpentine twisting path, the Tremola Pass in Gotthard is a wonder of 19th-century road design. After navigating its many twists and turns, enjoy one of the famous sausages sold from a hut at its summit. Finally, if the Furka Pass looks familiar, it’s likely from its big-screen appearance in Goldfinger. Fortunately as you drive to the highest point on the Grand Tour, at 7,969 feet, you’ll be able to simply enjoy the scenery without any villain in pursuit.
