Best walks in the Brecon Beacons National Park

From spectacular ridgelines and mountains to glistening waterfalls, rivers and lakes, the Brecon Beacons National Park in South Wales has something for everyone. Our guide looks at the best walks in the Brecon Beacons – all within an hour's drive of several major cities.

The Brecon Beacons National Park was designated as a national park in 1957, later achieving International Dark Sky Reserve status in February 2013. The park covers an area of 519 square miles and comprises four regions: the Brecon Beacons, Black Mountains, Fan Frycheiniog and Forest Fawr, each with its own bounty of beautiful walking routes.


Head to Waterfall Country in the south and take a hike along a gushing river to a series of impressive cascades, or visit the verdant valleys and ridgelines of the Black Mountains in the east. Many people seek the highest mountain, Pen y Fan, but there are plenty of other, quieter mountains with equally exciting walking routes.

Our guide explores some of the best hiking routes in the Brecon Beacons, each with its own walking map and set of directions.

“I cannot call to mind a single valley that… comprises so much beautiful and picturesque scenery and so many interesting and special features.” With these words, Victorian naturalist Alfred Russel Wallace was describing neither the Amazon nor the Far East that he explored on his intrepid travels, but somewhere much closer to home: the Vale of Neath on the southern slopes of the Brecon Beacons. Spilling water, mossy riverbeds and tree-shrouded caverns – Waterfall Country is a ramblers dream – find out for yourself with this 4km walk.

Cribyn, Powys

Cribyn, at 795m, sits 101m below the tallest peak in southern Britain, Pen y Fan. But far from inferior, the angular mount affords spectacular views over the surrounding countryside, making it well worth the climb

Often overshadowed by its towering neighbour, Pen y Fan, this verdant mountain in the heart of the Brecon Beacons National Park in Wales is one of Britain’s most understated peaks. It’s the kind of mountain a child may draw; pyramidal and stacked with brawn. Yet in spite of its mountain status, its summit is neither as high nor as insurmountable as you may imagine, making it well worth the climb.

Pen y Fan is one of the most popular peaks in the Brecon Beacons National Park. Most visitors hike to the mountain top from the Storey Arms – but for a quieter and more rewarding route, take the path up from Taf Fechan Forest past Neuadd Reservoir.

Take your time exploring the newly pedestrianised town centre, gather your treats, then set off on a lovely four-hour walk, taking in some beautiful countryside on the Sugar Loaf mountain just north of Aber.

Step out of your car at Keeper’s Pond and look out over the Black Mountains. The instantly recognisable flat top of Sugar Loaf mountain rises above Abergavenny and, on a clear day, you can pick out the Brecon Beacons’ highest peaks, Pen y Fan, Corn Du and Cribyn to the west. The surrounding landscape bears scars from the industrial activity the area is famous for; coal mining has left black furrows in the hillside, evidence of limestone and ironstone quarries litter the landscape and bell pits pockmark the ground behind the car park – the starting point of this 16.6km walk.

This energetic circular walk meanders in and out of the Brecon Beacons National Park, negotiating the scenic Hatterall Ridge that separates England from Wales. Lying in the Vale of Ewyas, the evocative ruins of Llanthony Priory, a 12th-century Augustinian abbey, can also be enjoyed on this 4.5-mile circular walk.

There’s no easy way to get to the summit of this mountain, which rises more than 750m above sea level. You can approach it from the long, sprawling mass of Bryn and the boggy uplands of Waun Rydd, or from the west and the Central Peaks of Pen y Fan and Cribyn. This 8km circular walk, our favourite route to the Carn Pica summit, begins and ends at Talybont Reservoir.

Little known and seldom celebrated, these towering rocky crags are within an hour’s drive of Cardiff and Bristol – yet people insist on travelling further in search of such mountainous drama.

Perhaps the hardest part about this day out is finding the car park; pass the small community of Llanddeusant and you know you’re close. Parking up in the small, gravel car park, you’ll already be aware of the solitude of this part of the Brecon Beacons – it’s the quiet understudy to the neighbouring central peaks of Pen y Fan, Corn Du and Cribyn, yet certainly no less spectacular.

The Brinore Tramroad fell out of use more than 150 years ago, yet evidence of the primitive railway still haunts this quiet valley in the heart of the Brecon Beacons. Explore this old track on a short walk from Talybont-on-Usk along the tramroad and back along the Caerfanell River.
