Hiking in the Brecon Beacons

Now known by its ancient Welsh name, Bannau Brycheiniog (the former Brecon Beacons National Park) encompasses an impressive 520 square miles/1,347 square kilometres of prime hiking territory. This dramatic landscape takes in remote moorland, steep climbs and undulating ridges with inspiring mountain views.

Our selection of the best Brecon Beacons hiking routes include plenty of challenging options, including the magnificent horseshoe ridge walk around the park’s highest peak, Pen y Fan, along with two consecutive sections of the long-distance Beacons Way. All of them shoud deliver a satisfying day out for even the most seasoned of hikers.

The best hike in the Brecon Beacons - The Horseshoe Ridge

 

Length: 10 miles (16 kilometres)
Difficulty: Challenging
Time: 5–6 hours
Start point: Taf Fechan Forest Car Park

There are numerous routes that you can follow around Pen y Fan, but we think this circular walk visiting four of the park’s highest peaks is the best hike in the Brecon Beacons for experienced walkers. Along the way you can visit Pen y Fan itself (886m/2,907 feet), Corn Du (873m/2,864 feet), Cribyn (795m/2,608 feet) and Fan y Big (719m/2,359 feet). The terrain features steep climbs, unmade pathways and an airy ridge walk, rewarding the adventurous with some spectacular views. 

Horseshoe Ridge route:

From Taf Fechan car park, head north towards the Lower Neuadd Reservoir and make the steep climb to Craig Fan Ddu ridge, where the summit of Pen y Fan dominates the view ahead. 

Head north along the ridge towards Corn Du. Stop to admire the glacial valleys to your right – a humbling reminder of the vast geological powers that shaped the park. 

At Bwlch Duwynt, head straight on to visit the Bronze Age cairn at the peak of Corn Du before returning to the path.

Continue along the ridge to the summit of Pen y Fan. Take a breather and congratulate yourself for your efforts.

After the steep descent from Pen y Fan you join the path down Craig Cwm Sere, then it’s a steep climb to the summit of Cribyn for a memorable view of Pen y Fan’s vertical north-east face.

From Cribyn’s cairn, follow the ridge along the back of the peak. Take care – this stretch is often boggy due to the eroding peat.

Continue down to the Gap Road, with a detour to the summit of nearby Fan y Big If you still have some energy to burn.

Return to the road, turn right and continue back to the car park.  

Other great hikes in the Brecon Beacons

Here are a couple more suggestions for serious hikes in Bannau Brycheiniog, taking in two of Pitchup’s favourite sections of the renowned Beacons Way.  

The Beacons Way

It takes around eight days to complete the whole of the 99-mile (159km) long-distance Beacons Way. Covering the length of the Bannau Brycheiniog National Park, it includes many demanding climbs and descents, and limited waymarking and remote terrain mean that map-reading skills are essential. All of these things make it a good choice if you’re seeking solitude, access to lesser-visited areas and a proper challenge. 

Of course, we know that not everyone has that much time to spare, so we’re suggesting two consecutive sections of the route – hikes that include testing climbs and open moorland with no waymarking. 

These are trails for experienced hikers, so make sure you’re well prepared. Check the weather forecast before you go – high winds and heavy rain could add an extra level of difficulty to the more severe sections. We’d recommend hiking in spring or summer, when longer daylight hours and better weather are on your side. Proper bad-weather gear, a compass and Ordnance Survey maps of your chosen area are essential.

Storey Arms to Craig-y-Nos

Length: 14.5 miles (23.5 kilometres)
Difficulty: Moderate
Time: 6 hours
Start point: Storey Arms

This route is in a quiet area of the park – if you’re lucky, you’ll have the trail to yourself. Keep your eyes peeled for buzzards, kestrels and peregrine falcons soaring on the air currents above, and look out for Arctic-alpine wildflowers like purple saxifrage and serrated wintergreen on north-facing rocky cliffs. 

Route:

From Storey Arms, follow the rugged path to the edge of the escarpment above the Craig Cerrig Gleisiad a Fan Frynych National Nature Reserve. From the plateau at the summit, continue along the ridge of Fan Dringarth and Fan Llia.

Continue down from Fan Llia, then join the Sarn Helen Roman Road.
