I'm going to be doing the Lon Las Cymru south to north in a few weeks, peeling off towards the end to meet up with some friends in Capel Curig. Looking at the map I'm a bit worried that the only roads across to Capel Curig look like main roads (A4086 and A5). Does anyone know what they're like? I could come in from the north and follow route 82 quite a way down the A5 to Llyn Ogwen. Looking at Google Maps there seems to be a track to the south of the A5 and River/Afon Lluygwy. Does anyone know if this is cycleable? I don't want to end up cycling on a fast busy road.
