This is a lovely 6 mile walk with fine views along the ridge of Myddfai mountain. Best on a clear day.

This walk begins on the quiet road heading north-east, past Seion chapel. Follow the road for half a mile: when you get to Pentwyn, take the right hand fork heading steeply down then uphill. Follow this road (for around a 1 ½ miles) until it ends at Cymnantybeudy. Carry on along the track past the farm (on your left): you'll see a sign for the Physicians' well where the track bears right uphill towards a stile. Once over the stile, you are on common land that stretches across the mountain and many miles beyond.

From here you can pick out the steep upward path heading almost directly to the top of the mountain. As you near the top the path begins to peter out - if in doubt, take the most uphill route. You'll see fencing just shy of the peak, which you cross at the stile.

At the trig point it's worth pausing to take in the 360 degree views. On a clear day you can see some of the highest peaks in the Beacons, with Pen y Fan to the east and Fan Brycheiniog to the south. The Towy valley lies to the West and the Cambrians to the north.

Follow the path along the ridge south-west for about a mile. This will take you down and then up along a sheep track to the next peak marked by a small trig point. From here, veer a little to the right (west) down the mountain, heading for a disused stone pit (with a fence below you). On the other side of the stone pit, the path will fork: ignore the downhill path to the left, and take the right fork (briefly upward, then down) that curves northward around the mountain. As you descend you'll have views of Myddfai and Esgair Llaethdy (home of the first Physicians of Myddfai) immediately below.

When the path reaches the fence at the bottom of the mountain, turn sharp right, following the path next to the fence. When you reach a gate, turn left through it and head downhill (back into farmland). Look out for a metal gate on your right. Go through it, across the stream and the stile opposite., Bear slightly left through the field towards another stile, and head downhill to Cwmclyd farm. Go through the farmyard, then up the track back to the road. Turn left, and follow the road for just over a mile back to Myddfai.
