Tips from the Community
A bit wet and boggy, possibly better to go around during wet weather/winter if you're not equipped for puddle diving.

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.

The views over Alwen Reservoir from this section along the northern shore are simply wonderful! You'll take them in if you follow the waymarked Alwen or Lakes Circular routes. You move between open views and between the trees, but both are pretty spectacular, especially at sunset.

The grand, ornate stone dam of Alwen Reservoir couldn't be more of a contrast to the neighbouring Llyn Brenig Dam. It's well worth taking a minute or two to take in this magnificent feat of engineering, that was completed in 1920. The reservoir here was built to provide drinking water for Liverpool and the Wirral.
