Amazing views across the Carmarthen fans

Garreg Las (Twyn-Swnd) is on the west side of the Black Mountain range, and it is visited far less often than many peaks in the Brecon Beacons. Its remoteness is its draw for me; rarely will you be unindated with a host of other walkers here. It is also hansomely topped by a pair of substansive, rocky ancient cairns. You can come across from the car park on the A4069 Brynaman Road or come up from Llanddeusant; both are equally as appealing, but the Llanddeusant route takes the top slot if you go back via Llyn y Fan Fach; this route has the best views. The views from the summit itself are like the location: raw and remote, but I love the place. It is a good area for a bit of navigation practice. At 635 metres high, it is a UK-listed Nuttall and Hewitt. Tip: Any Welsh place name with Llan in it means it has a church. In this case, Llanddeusant means the church with two saints.

At just 440 metres Tair Carn Isaf is a modestly sized hill, but its prominence at the western end of the Black Mountain, high above the Amman Valley, affords extensive views over central south Wales, into Powys, west to the Preselis, and over the Gower Peninsula and Severn Estuary.

January 24, 2024, Herbert's Quarry

Herbert’s Quarry is part of the Black Mountain and Mynydd Myddfai Registered Landscape of Outstanding Historic Interest in Wales. Unlike in other lime producing areas where canals and tramroads could be built, the industry at Herbert’s Quarry was served solely by road transport. The lime trade was a factor in the development of Turnpike roads, and the network of tracks and roads over the mountain is closely associated with the activity at Herbert’s Quarry. As you walk through the site you are taking a journey through time, and walking in the footsteps of many hundreds and thousands of people before you, people whose hard work, sweat and drudgery shaped this landscape and left a rich industrial legacy.

Abandoned limestone quarry. You walk among the remains of lime kilns and dumps dating from the past two centuries. It now also appears to be a popular bouldering site. The Welsh name for the site is Foel Fawr Limestone Quarry.

Glorious views all round but the Komoot app struggled to track me in real time. It kept demanding I turns. I fear it may be disadvantageous if you don’t also read a map as this is a bleak area to get lost in.

Tair Carn Isaf at 460m stands at the western end of the Brecon Beacons National Park. This position creates amazing views south over the Gower and out to the Bristol Channel and west towards Pembrokeshire. There are three stone cairns on the summit, one has a trig point.

Frequently Asked Questions

Are there any easy, family-friendly walks in Quarter Bach?

Yes, there are many options suitable for families. The area around Herbert's Quarry is a great starting point for shorter walks. For a very accessible route with rewarding views, consider the Herbert's Quarry & Garreg Lwyd loop. It's a short walk to a summit cairn, making it manageable for little legs. The Amman Valley also offers a gentle, traffic-free riverside path.

Can I bring my dog on hikes around Quarter Bach?

Dogs are welcome on most trails, but the area is characterised by open moorland with grazing livestock, so it's essential to keep your dog on a lead. Trails starting from Herbert's Quarry, such as the Carn Pen-rhiw-ddu & Tair Carn Isaf loop, are popular with dog walkers. Always be prepared with water for your dog, especially on longer routes across the exposed hillsides.

Where can I find hikes with waterfalls near Quarter Bach?

While many routes feature streams and beautiful water features, the most famous waterfall in the region is Henrhyd Falls, the highest in South Wales. You can find several walking routes that incorporate a visit to the falls. The Limestone Trail, accessible from Herbert's Quarry, also leads past smaller, picturesque waterfalls.

What are the parking options for hikes in the area?

A key starting point for many popular walks is Herbert's Quarry, which has a car park. This provides direct access to trails leading up to Garreg Lwyd and onto the Black Mountain moorland. For other routes, parking may be available in the village of Upper Brynamman or at designated lay-bys. It's always best to arrive early, especially on weekends, as spaces can fill up quickly.

Are there any circular walks available?

Yes, the majority of the popular trails in Quarter Bach are loops, allowing you to start and finish in the same place without retracing your steps. There are options for all abilities, from short, easy loops to more challenging moderate hikes. A great example of a longer circular route is the Foel Fawr Limestone Quarry – Herbert's Quarry loop, which explores the area's distinctive quarry landscape.

What kind of hiking should I expect in Quarter Bach?

Hiking here is defined by the wild and remote landscape of the Black Mountain range. Expect trails across open moorland, past historic limestone quarries, and up to summits with panoramic views. The terrain is often rugged and exposed, so be prepared for changeable weather conditions, even on a clear day.

How many hiking trails are there around Quarter Bach?

What is the best time of year to go hiking in Quarter Bach?

You can hike in Quarter Bach year-round, but late spring and summer offer the best conditions with longer daylight hours and warmer weather. Autumn is also a beautiful time to visit, as the moorland colours change. Winter hiking can be rewarding but requires experience and proper gear, as conditions on the Black Mountain can be severe.

What should I wear for a hike in this region?

Given the exposed nature of the Black Mountain and the unpredictable Welsh weather, layers are essential. Always pack a waterproof jacket and trousers, even if the forecast is good. Sturdy, waterproof hiking boots with good grip are a must for the often boggy and uneven terrain. In summer, a hat and sun cream are also vital.

Are there any pubs or cafes near the walking routes?

After a long walk, you can find pubs and cafes in the nearby villages such as Upper Brynamman and Glanaman. These offer a place to relax and enjoy a meal or a drink. It's a good idea to check opening times in advance, particularly if you plan to finish your hike later in the day.
