The bike path is not accessible throughout because the river has washed away parts of it. It is also not crossable on foot.

I'm 12 and rode for the first time when I was 10. It's my favorite Alpine climb. All I can say is that it's best to take a break in the corner so you can fill up your bottles and go to the toilet if necessary.
