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!!

A long and winding doubletrack gravel road that flanks the eastern shore of Llyn Brenig. It's a little rough in places so best on a gravel bike, sturdy hybrid or mountain bike rather than a pure road bike. Enjoy the views as you meander around the little inlets and see what wildlife you can see across the water.
