Stelvio Pass, Italy

Located in the Eastern Alps in Italy, the Stelvio Pass Road connects the Valtellina with Merano and the upper Adige valley.
This mountain road pass is situated at an altitude of around 1.7 miles above sea level. 
The road is particularly challenging to drive due to the presence of 48 hairpin bends, with the road becoming exceedingly narrow at some points, and some very steep inclines.
With a height of 2757 meters, it is the highest paved mountain pass in the Eastern Alps and the second highest in the Alps, after the 2770 m high Col de lIseran. While it might not be as dangerous as the other routes, it is certainly breathtaking.
The toughest and most spectacular drives are from the Prato side.
The mountain pass is one of the best continuous hairpin routes in the world.
