Moorland & sky Sheep on the moorland Magnificent Reaching the Pen y Fan


Start the hike from the car park opposite Storey Arms Centre (on the A470, 15-20 minutes from Brecon).

(D) Cross the road, pass the gate and make your way uphill due north-west keeping the forest on your right-hand side.

After thirty odd minutes you'll start to see the Corn Du (873 m), the first peak of the day. However, you'll need to head downhill over 5 m and cross a ford in order to reach it.

(1) From the stream, the slope is steeper but is not difficult (wide track).

(2) Approximately 30 minutes later, you'll come across a large ridge overlooking a vast cirque and the outskirts of Brecon laying at the back of the fields. You can spot a beautiful lake further down to your left, Llyn Cwm Llwch, and to your right, behind Corn Du, Pen y Fan. You'll also notice sheep climbing on impressively steep slopes that would make even ibexes jealous!

The path continues to the right heading south-east up the ridge reaching Corn Du.

(3) At the top of Corn Du, keep going along the ridge due north-east. The trail goes down a few metres reaching a pass then heads up again reaching Pen y Fan.

(4) The view must be breath-taking from Pen y Fan... unfortunately, we were surrounded by fog so didn't get that chance to see it...

(5) You'll get to another pass by an intersection. Follow the main path which heads down the mountain side due south-west. It's a quick descent which leads you to the initial forest to the left.

(6) After crossing a bridge over the stream, you'll get to a car park on the edge of the A470. Head up the track which goes along the forest (north-west) reaching your starting point within a few minutes.

The route continues on the west-to-east Brecon Beacons Way, now over halfway to its final destination at Abergavenny Station. This is possibly the most strenuous day's walking as there are a number of climbs, starting with Corn Du and Pen y Fan. However, on a clear day, the views are spectacular.

Starting point Starting point in Llanddeusant - Carmarthenshire

This is a brilliant linear trail in the Brecon Beacons National Park, incorporating many good viewpoints and one extra-special one. It begins in Carmarthenshire near the village of Llandeusant and ends in Powys in the Glyntawe valley, crossing a mountain ridge that beats Pen-y-Fan in my view, but because it's less accessible is less well-known.

distance 9.96mi Vertical gain +2215ft Vertical drop -2431ft Durée 6h30 Average Average
Starting point Starting point in Llanddeusant - Carmarthenshire

The route leaves Llanddeusant and heads into the Black Mountains on the third leg of the Brecon Beacons Way. It's generally a walk south along ridges and mountain tops to finally drop down to the Craig-y-nos Country Park on the Afon Tawe river.
