The beginning is enduro light, after which it progresses more smoothly and becomes increasingly unspectacular. Still a fun ride!

Many dips invite you to play around on your bike. Nothing special, but quite nice if you happen to be passing through.

One of the more difficult sections in the area. Some people will probably have to push. The roots aren't too nasty, but the slope, sometimes in one direction and sometimes in both directions, makes the fall zone unfriendly to the bones.

This part of the tour is really tricky. There are steep descents to the right and left of the path. It is very exposed in places and the stones and roots cannot be seen with the autumn leaves 😬🙃
