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!!

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.

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 (370 m) above sea level on the border between the counties of Conwy and Denbighshire. It is used to manage the flow in the River Dee as part of the River Dee regulation system.

Here you have a super good section of singletrack as you meander your way through Gors Maen Llwyd nature reserve to the north of Llyn Brenig. You have fine views but don't let it distract you too much as walkers use this track as well.

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.

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.
