I stayed at these two places on a Cwmcarn to BPW bike trip, carrying a change of riding clothes with us – both are great for different reasons. They’re (bike) friendly with great accommodation with places to lock your bikes in.
Soar Chapel is near Ebbw Vale, so just off the heads of the valleys road, between Cwmcarn and BPW (good also for Forest of Dean and Brecons). If you go there, head to Ambala curry house in Ebbw Vale.
Mount Pleasant was a real find – 3 miles south on the Taff Trail from BPW, just outside Aberfan, so in the same valley as BPW. Website really doesn’t do this place justice – the rooms are good but it has a great little old bar in one room with wood burning stove to dry your shoes out, the best Guiness I’ve had this side of the Irish Channel, really good home cooked food and bike storage.
