Hi Robbie, been a long time since I was down that way, but the road through the the beacons is awesome for scenery, I was down there for some training in my army days a couple of times and loved the area - great hang gliding

Nice place to stop for a spot of lunch is Crickhowell, there was a really good pub right on the river next to a little stone road bridge, can't vouch for what it's like now though.
