Right now I'm in Italy, staying just minutes away from one of the greatest climbs in Europe: The Stelvio. The Stelvio is famously known as the road with never-ending hairpins, 60 in total. It also is the 5th highest paved road in Europe and 2nd highest paved mountain pass in Europe. It tops out at 9045 feet, and if you ride it you will climb over 5000ft of that in one fell swoop. Thinking about riding up it is a big task. How many bottles do you go through on a 2+ hour climb? How much nutrition do you pack? How much extra weight does that mean you'll be carrying? Well I'm not riding the Stelvio. I'm still off the bike with a broken wrist. So instead I climbed Colosso di San Carlo. With the Stelvio far off in the distance, this gigantic statue sits right outside the town of Arona. Over 115 feet high (40 feet shy of the Statue of Liberty), for a mere 4 euro you can go inside the statue and climb straight up a narrow, enclosed, completely vertical and somewhat overhanging shaft, with a not so safe ladder into the head of San Carlo and look out his nose, ears, and eyes.
If you find yourself in Europe, unable to ride the Stelvio's switchbacks, Colosso di San Carlo is definitely an adequate replacement.
