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.

Carreg Cennen Castle is erected sometime after 1284 by Baron John Giffard and his son on the site of an earlier Welsh fortification. In 1462, Carreg Cennen flies the Lancastrian flag. Taken on behalf of the Yorkist king Edward IV, it is slighted by pick and crowbar, ending its life as a stronghold. Carreg Cennen castle is spectacularly located on a great limestone crag about 90m above the river Cennen, offering views miles around.

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.
