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.
