Pen-y-Gaer Road, Panorama, Dinas Bran Castle, Llangollen, Horseshoe Pass, left just past the Ponderosa, left then left again to Bryneglwys, Carrog, Horseshoe Falls, Llangollen, then the canal all the way to where it ends near the Duke of Wellington, then back up via Tower Hill 🙂
3 and a bit – 4 and a bit hours? and not too much climbing (other than Horseshoe Pass and Tower Hill, but TBH you can’t ride much around the area without some climb or another!)
All fairly quiet roads too (except HSP, but you could try the ‘old’ pass for a laugh, Pentredwr to the Ponderosa).
Will try and go a google map thing now.
