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!!

Llyn Brenig is a reservoir located on Denbigh Moors in North Wales. The artificial lake, which was constructed between 1973 and 1976, was created by building an embankment dam across the Afon Brenig valley. It lies at 1,200 ft above sea level on the border between the counties of Conwy and Denbighshire.

A long wooden bridge spans the upper reaches of the Alwen Reservoir, which features on the Two Lakes and Alwen circular cycle routes. It's absolutely covered in lichen and feels a little rickety as you ride along. Enjoy the remote lake views as you ride over this long, narrow bridge.
