Garreg Lwyd Summit

Highlight • Natural Monument

South Wales' westernmost 2,000-footer at 2,021 feet (616 m), Garreg Lwyd is the last high outpost of the Black Mountain range. It makes for a very quick ascent from the A4069 road, where you can also explore the quarry workings, pits and lime kilns of Herbert's Quarry. Garreg Lwyd is also easily linked with Foel Fraith, its slightly smaller sibling to the east.

Foel Fraith

Highlight • Natural Monument

With its northern slopes hewn from limestone and the rest by Twrch Sandstone, Foel Fraith is a hill of contrasting sides. Its summit is relatively unfrequented and features a broad, grassy plateau that rewards with lovely views of the surrounding countryside. The Beacons Way long-distance trail crosses Foel Fraith on its way between Llanddeusant and Carreg Cennen Castle.

Foel Fawr Limestone Quarry

Highlight • Climb

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.

Herbert's Quarry

Highlight • Historical Site

Also referred to as Black Mountain Quarry, Herbert's Quarry ceased operation in the late 1950s and since then its buildings have fallen into ruin. The remains and spoil heaps tell the story of 200 years worth of lime burning and the production of quicklime for agriculture.
