The deep lake of Llyn Aled is located high on the Hiraethog moors. The shoreline is treeless and this bleak location at 250ft above sea level can be breezy, but the surrounding moorland and views are beautiful.

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.
