Leave performance anxiety aside and take a few stops to enjoy the surrounding panorama: the Colle del Nivolet is one of the most panoramic climbs in the Alps. The final hairpin bends overlooking the lakes are truly special.

July 11, 2023,Colle del Nivolet con fuori programma 🚴🏊‍♂️

I know that doing 1300m dry is not like doing it after 130km, but getting to the top pedaling through incredible landscapes, uphill, marmots and foxes is still a great satisfaction. Halfway down the descent we also found time to take an unscheduled bath (I think the water didn't go above 4 degrees... 🥶🥶): Still fantastic 😊😊😊😊

Probably the most beautiful climb in the Alps. You go up from Locana, full version with 40km of ascent, or from Ceresole. Since they fixed the very steep stretch outside the tunnel, it's worth starting from Locana.
