Tips from the Community
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!!

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.

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.

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.
