Passo dello Stelvio is a 2785-meter-high mountain that is both breathtaking and unforgiving. The climb from Prato includes no fewer than 48 hairpin bends, and you conquer 1871 meters in altitude with an average gradient of 7.5% over 23 kilometers (about 14.29 mi). It’s one of the toughest, yet most beautiful climbs in Europe.
The journey starts from Prato, along a river surrounded by towering rocks. The gradient here is manageable, but it remains important not to give it your all right away, as it will get tougher. Once you enter the forest, the climb becomes steeper. Along the way, you'll pass through some lovely villages, and there are several fountains where you can refill your water bottles.
