The Migneint
B4391A4212Llanycil to Bont Newydd
A wild, empty moorland crossing in the heart of north Wales.
The B4391 crosses the Migneint, one of the largest and emptiest blanket bogs in Wales, between Bala and Ffestiniog. It is open and lonely with long sightlines and sheep on the road; a glorious quiet run, but carry fuel and watch the weather.
