Fairly easy and fun. Not good in winter because there are several big long puddles with no way around.

Detour from the road below it, little more elevation change id say than the road. More fun I’d say, adds time whichever direction you’re going. Old road that just had singletrack worn in now
We hope you've been enjoying Trailforks!
