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!!

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.

Llangower provides access to the lakeside for walks, picnics and bird watching. The stop also offers access to the car park and adjacent toilet facilities provided by the Snowdonia National Park. There is a passing loop and small signal box here which is used on gala days and for the pink timetable to allow trains to pass. A beautiful little picnic area for a stop and a break before cycling them hills again.

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.

At 6km long and 0.8km wide, Llyn Tegid is the largest natural lake in Wales. The glacial lake formed in the fault line between Bala and Tal-y-Llyn towards the end of the last ice age. The receding glacier left a recessional moraine which dammed the valley and created the lake. Today it's a popular tourist and sport venue with lots of water sports and fishing on the lake and walking trails around it.

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.
