Part 2: The Brecon Beacons
Mountains, Market Towns & Open Skies
Beyond the valleys, the Cambrian Way rises into the wide, breathing spaces of the Brecon Beacons National Park. The sense of enclosure fades, replaced by long ridges, open moorland, and a landscape that feels older, calmer, and more elemental.
Here, the journey changes pace. Driving becomes more scenic, distances feel less important, and the temptation to stop — for viewpoints, short walks, and quiet exploration — becomes part of the experience. Towns like Brecon and Builth Wells sit gently within the landscape, acting as natural bases for exploring hills, rivers, and valleys rather than dominating them.
This is a section shaped by geology and water: escarpments, waterfalls, high passes, and wide skies. It’s also a place where military history, farming traditions, and outdoor culture meet. The Brecon Beacons form a natural transition zone on the Cambrian Way — leaving the industrial south behind and easing you into the deeper, wilder landscapes that lie ahead.
How to Spend Your Time
This part of your journey takes you through the rugged beauty and rich heritage of the Brecon Beacons — from windswept hilltops and shimmering reservoirs to welcoming towns filled with culture and character. Whether you're up for a full-day hike or a gentle towpath stroll, the National Park offers a wide range of ways to enjoy the outdoors.
In the historic town of Brecon, take time to explore its military past, canal walks, and peaceful cathedral. Further north, Builth Wells is a charming riverside stop with Welsh legends, craft centres, and a proud agricultural heritage at the Royal Welsh Showground.

The church
Cloister

Llanthony Priory was founded in the early 12th century by Augustinian monks, under the patronage of the Norman nobleman Walter de Lacy. Its location, deep in the remote Vale of Ewyas in the Black Mountains, was chosen for its isolation and spiritual atmosphere, but this same remoteness would also shape its turbulent history.
Originally established as a small religious community, the priory grew in wealth and importance over time and eventually became one of the more significant monastic houses in this part of Wales. However, its position close to the Welsh Marches made it vulnerable to border conflicts and raids, and the community suffered repeated attacks during periods of unrest.
Because of these difficulties, the monks at one point even abandoned the site temporarily and focused their efforts on a daughter house in Gloucester, before later returning to Llanthony.
Despite these setbacks, the priory continued to function for several centuries as a place of worship, learning, and administration, with monks engaged in prayer, study, and the management of surrounding lands.
Like many religious houses, Llanthony Priory was finally dissolved in the 16th century during the Dissolution of the Monasteries under Henry VIII. After that, the buildings fell into ruin, gradually becoming the atmospheric remains we see today.
Today, the priory is valued not only for its historical importance, but also for its extraordinary setting, which gives a powerful sense of the isolation, beauty, and hardship that shaped monastic life in medieval Wales.
-
Location:
Llanthony Priory is located in the Vale of Ewyas in the Black Mountains, on the western edge of the Brecon Beacons National Park.Important route note:

The priory is best reached by car via narrow, scenic mountain roads.
The approach roads are steep and winding in places and form part of the experience, but take your time, especially in poor weather.
Parking:

Access:
The site is in a remote rural setting.
Paths and ground around the ruins can be uneven and muddy, so good footwear is recommended.

Brecon
Brecon (Welsh: Aberhonddu) is a historic market town in the heart of the national park, founded around a Roman fort (c. 75 AD) at the meeting point of the River Usk and River Honddu.
It developed into an important Norman stronghold with Brecon Castle and later grew through brewing, textiles, agriculture, and improved transport links via canal and railway.
Today, it is a lively and attractive base for exploring the Brecon Beacons.

-
Brecon (Welsh: Aberhonddu) began life as a Roman settlement, built around a fort established around 75 AD to control routes through this part of Wales. The Romans chose the site because it sits at the strategic meeting point of the River Usk and the River Honddu, a natural crossroads for movement through the region.
After the Norman conquest, the town became an important border stronghold. Brecon Castle was built in the late 11th century to secure control of the area, and the town developed around it as a military, administrative, and trading centre. During the medieval period, Brecon grew into a significant market town serving the surrounding upland farming communities.
In the 18th and 19th centuries, Brecon’s role shifted again. Although it was never an industrial giant like Merthyr Tydfil, it became an important market, administrative, and transport hub, helped by the arrival of the canal and later the railway, which connected it to the wider Welsh and English economy.
Today, Brecon’s streets, cathedral, and mix of historic buildings reflect these many layers of history — from Roman frontier town, to Norman stronghold, to Georgian and Victorian market centre — making it one of the most characterful towns in the Brecon Beacons.

Y Gaer Museum, Art Gallery & Library – For a quick cultural stop
Or continue towards the canal
3) Monmouthshire & Brecon Canal Basin
Head to the Brecon Canal Basin, where the Monmouthshire and Brecon Canal ends. This is a peaceful and scenic area with narrowboats, towpaths, and waterside views.

The Llywelyn Memorial
© Crown Copyright
-
Llywelyn ap Gruffudd (c. 1223–1282), often known as Llywelyn the Last, was the final native Prince of Wales and one of the most important figures in Welsh history.
He was the grandson of Llywelyn the Great and rose to power during a period of constant conflict between Welsh princes and the English crown. By 1258, he was styling himself Prince of Wales, and in 1267 the English king Henry III formally recognised his title in the Treaty of Montgomery, making Llywelyn the only Welsh ruler ever to be officially acknowledged as Prince of Wales by an English monarch.
Llywelyn spent much of his rule trying to unite Wales and defend its independence from English control. However, when Edward I came to the English throne, relations deteriorated rapidly. Edward launched a series of invasions of Wales, gradually stripping Llywelyn of territory and power.
In 1282, Llywelyn joined a renewed Welsh uprising led by his brother Dafydd ap Gruffudd. During the campaign, Llywelyn was betrayed and ambushed near Cilmeri, close to present-day Builth Wells. He was killed in the skirmish, and his head was sent to London as a warning to others.
His death marked the effective end of independent Welsh rule. Within a year, Edward I had completed the conquest of Wales, and the title Prince of Wales was later adopted by the English crown.
Today, Llywelyn is remembered as a symbol of Welsh independence and resistance, and the memorial at Cilmeri stands as one of the most poignant historical sites in Wales.
-
Location:
The Llywelyn Memorial is located at Cilmeri, a small village just west of Builth Wells, beside the River Wye.Getting there:
Best reached by car from Builth Wells — it is only a short drive.
Follow local signs for Cilmeri and the memorial site.
Parking:
There is parking near the memorial, with a short, easy walk to the monument.
On arrival:
The memorial is in a quiet, rural riverside setting.
Paths are generally easy and short, but may be muddy after wet weather.
Visiting time:
Allow 20–40 minutes for a visit, or longer if combining it with a walk along the river.
Good to know:
This is a place of reflection rather than a large attraction — there are no visitor facilities on site, so it’s best combined with a visit to Builth Wells.
Just west of Builth Wells is the The Llywelyn Memorial at Cilmeri, marking the place where Llywelyn ap Gruffudd, the last native Prince of Wales, was ambushed and killed in 1282. His death marked the end of Welsh independence and remains one of the most important symbolic sites in Welsh history.
The memorial is a quiet, reflective place to visit and adds an important historical dimension to any stay in the area.
