The road runs along the top of open more land and then drops down the side of the mountain if you continue on to Llangynidr on a clear day you will be able to Llangorse lake and if you are lucky you might see some of the car magazines up here road testing. (Evo and Top Gear use this road) Just after you drop down the side of the mountain about 1/2 a mile on there is a car park with excellent views of the Beacons and an ideal place to park for sunset photos. After the car park on your left you will come to the first of 2 hairpins and a steep drop down to the 2nd. After you cross the cattle grid the road tightens then and drops down to the village of Llangynidr where you can stop for drink at the Coach and Horses.
From the A465 (heads of the Valleys Road) heading towards Abergavenny. After the roundabout for Ebbw Vale, take the next left and then turn right and follow the road (this is the B4560) Continue on here to Llangynidr which puts in some good hairpin bends or turn right at the next junction and go on to Crickhowell
