Passo Gavia from Bormio is the much easier route to the top of the pass. No tunnel and much milder grade - 5.26% versus 8% from Ponte di Legno. This route is scenic (not quite as breathtaking as the traditional side) and is a very nice out-and-back with both sides tacked on - 50 miles (80km) with 9,000’ (2,743).
With Stelvio, one of the best spots to finish in Europe . . .
