B5113 (Colwyn Bay)
South of Bryn-y-maen and its 'Cathedral of the Hills' church, the B5113 climbs onto the broad ridge that runs parallel to the Conwy Valley and stays up there for most of these eight miles, on the western edge of the Denbigh Moors. The surface is good and the road is a full two lanes, so the steady run of corners can be treated as a rhythm exercise; the Carneddau sit across the valley one way, the Great Orme and the sea the other.
There is barely a hamlet between the B5381 crossroads at Glasfryn and the descent towards Llanrwst; a small lay-by below Mwdwl Eithin's trig point is the one obvious place to stop, and the sheep on the plateau spook easily.
