From the layby walk towards a bridge and a small picnic and go through the adjacent kissing gate (signposted to Twyn Dylluanddu and Forest Lodge). Head towards the crags, following a clear footpath, until you come to a gap in the next wall.
Go through this and make a right turn to follow a drystone wall north. Head down into a small valley, cross the stream, then a stile to continue in the same direction. Drop into another, steeper, valley and climb out, still following the track. Follow through the bracken to a stile.
Cross and turn left on to a stony track. Continue up to a gate and a stile and then through rough ground, churned up by mining, until it levels on a dished plateau. Bear right here to the whitewashed trig point of Fan Frynych, then turn sharp left to return to the main track above the escarpment.
Bear right back onto the main track again and go past more rough ground before dropping slightly into a broad but shallow valley. At the bottom, go over a stile by a gate.
Cross another stile on your left and turn right to continue in the same direction, this time with the fence to your right. Climb up to the highest point, then follow the obvious path around the top of the cliffs. The path starts to drop, easily at first but getting steeper as you go.
Follow carefully down the steep section and follow the path around to the left when you reach easier ground. This leads you to a stream, which you can ford or jump (it's narrower a few paces downstream). Turn right, through the gap in the wall, and follow the outward path back to the car park.
