Whenever I'm not sure where to go I end up on this route. It forms part of my return trip to Betws-y-coed over the Denbigh Moors. It's a guarateed grin factor ride. Travelling this route reversed, slow down after the cattle grid! The T-junction is approaching fast and not clearly marked.
The B4501 has some great bends, some strong drops with tight corners (some with limited visibility) but otherwise good visibility.
