You can head back to llyn brenig before you get to the section as a short cut, this but is not to be missed. Flows really nice, cutting through some old forest before a fun section along the lake.

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!!

Alwen Reservoir is the largest human-made lake in Wales and it makes for a lovely walk. There's a car park at its eastern end and the 6-mile (10 km) loop of the reservoir is wonderfully scenic and suitable for the whole family. The mixture of lake views, woodland and open moorland make it a real treat.

This bridge across the 900-acre (364 ha) Alwen Reservoir enables a beautiful and tranquil loop of the Wales' largest artificial lake. The views across the water and to the surrounding woodland and hills are lovely.
