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 idyllic mountain lake is hidden amongst the pine and deciduous forests of the Gwydyr Forest and lies above Betws-y-Coed. The lake is used as a water reservoir. In the past the lake was actually made up of two smaller lakes, called Llyn Rhisgog and Llyn Enoc.

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.

The construction of such a huge structure as this dam was hard and dangerous work at the time, without the technical resources available today. So it's nice that this monument keeps the memory of the construction workers alive.

As you can see ..... breathtaking views. though a few sections flooded, lucky I was prepared and brought over boot waders to knees. Planning is key in winter months up here.

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.
