The Stelvio route is an unforgettable alpine summer adventure with a cultural aspect. It passes through a high mountain area, connecting Val Müstair with the Veltlin region of Italy and is only open during the summer. The road, which is not fully paved, climbs from Sta. Maria up to the Umbrail Pass, an excellent starting point for mountain biking and hiking tours. Stilfserjoch is the highest stop of PostBus Switzerland and an interesting place to explore. During World War I this is where the Italian front was between 1915 and 1917 (also see Mountain War 1915–1918) and there are still some remains of the military fortifications from that time. The road descends via a number of hairpin turns down to Bormio, known for its thermal baths. Bormio is also a winter resort and host to world cup ski racing. By the time you reach the town of Tirano, you will undoubtedly feel that you are in Italy. Tirano is situated in the upper Veltlin region at the entrance to Val Poschiavo, near the Swiss border. The scenery in the old town is marked by churches, city gates and the palaces (palazzi) built by wealthy families during the Grisons rule. On the return trip from Tirano back to the Upper Engadine by the Rhaetian Railway passengers are sure to enjoy the exceptionally charming landscape. Between Tirano and Thusis the Bernina Express route is part of the UNESCO World Heritage.
