Those switchbacks remind me of some of the ones in Europe on Le Tour.
This particular climb would be a real challenge for all the Tour cyclists. It's one of the longer in the world. Start at 800m and the pass is at 4050m. Some very steep sections, which even Pantani (hail and RIP) would've liked.
I want to ride that!
It's a great ride. The changes from where you start are extraordinary. Desert - sandy hills - a long canyon - green meadows - pine forest - alpine area with glaciers.
