A good walk or ride. Easily achievable on a cheap MTB or a gravel bike. It's mostly gravel, which makes it a good all-weather route.

Though it was not a tough or technical ride, it did take me into territory I had never visited before and was a lovely antidote to the 'fleshpots' of Gwydir Forest or Coed-y-Brenin. Some lovely gentle singletrack, beautiful views and I didn't see another rider for the whole trip - although tbh I did set off at 08.30 on a Wednesday!!
