There are great views of Castell Carreg Cennen from here, looking north-west across the valley. The castle is perched gloriously on a rocky limestone outcrop, and its outer walls and towers look majestic and are a reminder of its former glory.

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.

The trails in Carmarthenshire are highly regarded by the komoot community, with thousands of hikers exploring the area. Reviewers often praise the region's diverse landscapes, from the dramatic coastline and quiet woodlands to the rugged mountain ridges.
Yes, the Cwm Lliedi Lower Reservoir — Swiss Valley loop is an excellent choice. It's a gentle 5.2 km walk around the reservoir that's suitable for all ages and offers a peaceful, scenic experience.
Dogs are welcome on many trails, but it's important to be responsible. In areas with livestock, especially in the Brecon Beacons and coastal paths, you must keep your dog on a lead. Forest trails, such as those in Brechfa Forest, often provide more freedom for well-behaved dogs away from farm animals.
Carmarthenshire is on the edge of 'Waterfall Country'. A popular nearby destination is Henrhyd Falls, the highest waterfall in South Wales, which you can even walk behind. The area offers several trails through a scenic wooded valley to reach the falls.
For a demanding day out, the Llyn Brianne Reservoir loop is a great option. This 23.7 km route involves significant elevation gain and rewards hikers with stunning, remote scenery around the reservoir in the Cambrian Mountains.
The Carmarthenshire section of the Wales Coast Path offers a mix of sandy beaches, salt marshes, and clifftop views. For a walk with historical interest, the Dylan Thomas loop around Laugharne combines coastal scenery with the town's cultural heritage.

The western part of the Brecon Beacons, known as the Black Mountain, offers some of the most dramatic hikes. A great moderate route is the Herbert's Quarry to Garreg Las loop, which takes you into the wild, open moorland of the national park.
The Herbert's Quarry & Garreg Lwyd loop is a short but rewarding 3 km hike. It climbs to the summit of Garreg Lwyd, offering expansive views across the Black Mountain landscape for relatively little effort.
Carmarthenshire has excellent forest walks. Abergorlech Forest is a popular spot with several well-marked trails of varying difficulty that wind along the Gorlech River. It's a great place for a sheltered walk on a windy day.
