Voted the 'Best Driving Road' in the world, the Stelvio Pass in the Italian Alps is one of the highest mountain passes in all of Europe. Riddled with 48 hairpin turns on your way up the mountain, it is another road that is (so very obviously) closed in snowy months. Of note is that the world's highest battle was fought here in WWI.
Lombardy, Italy Still mild even as the leaves fall, Lombardy in northern Italy is an ideal place to see mainland Europe burst into colour. The native Lombardy poplars, which can be seen across the landscape, turn a bright yellow before their leaves fall to the floor. If you can’t make it to the countryside, Milan’s public gardens offer a great city view of autumn.
