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.

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.

September 9, 2023, Carreg Cennen Castle

Ruin of a late thirteenth-century castle, on a limestone rock where there may already have been a fort in the Iron Age. The earliest castle was most likely the work of the dynasty of Welsh princes. The oldest found written mention of the castle dates "only" from 1248 when Rhys Fychan (died 1271), great-grandson of Lord Rhys, conquered the castle from the English. In 1277 the castle was captured by Edward I of England in his first campaign against Llewelyn ap Gruffudd of Gwynedd (died 1282).[1] The castle was briefly reconquered in 1282 and 1287. In 1282–83 Edward I completed his conquest of Wales and granted Carreg Cennen Castle in 1283 to his loyal supporter John Giffard (d. 1299), baron of Brimpsfield (Gloucestershire). The current castle was most likely built by Baron Giffard and his son John (died 1322), not too long after 1284. Being a resident of Ghent myself, I thought it was a nice fact that the castle was in the hands of John of Gaunt (yes, John of Gaunt), Duke of Lancaster, for a while in the 14th century. During the War of the Roses (1455-1485), Carreg Cennen Castle was initially in Lancaster hands, but was later conquered by the York supporters. In the late 18th century the castle became popular among amateur archaeologists and artists, with William Turner visiting the castle in 1798. In the 19th century the second Earl of Cawdor began restoration work on Carreg Cennen Castle. In 1932 the castle came under state management. In the 1960s the castle became the property of the Morris family, owners of the Castell Farm farm near the castle. Source: Wikipedia The castle can be visited 364 days of the year. Just not on Christmas Day. 9:30 am - 4:30 pm (from April to October until 5:00 pm) The ticket desk is located at the tea room / gift shop ("downstairs", where the parking is also located). In high season and on weekends, tickets can also be purchased near the entrance to the castle. Entrance prices range from £6.50 for adults, £4.00 for discount holders, to £20.00 for a family ticket.
