Mynydd Llangatwg

Mynydd Llangatwg is a limestone summit in Powys that rises to about 529 meters. The terrain displays a rolling plateau with limestone cliffs along the northern slope and various geological formations scattered across the landscape.

The hill contains multiple Neolithic stone cairns at Twr Pen-cyrn that point to early settlement. The northern slopes show traces of limestone quarrying and tramway construction dating from the 19th century.

The name Pwll Gwy-rhoc, known locally as the Witch's Pool, carries stories that echo through the area. Visitors encounter these spots as quiet places that stir the imagination.

The hill is accessible via several walking routes branching from the B4560 road, running from north to south. Good footwear and weather protection are advisable, as the elevation and open terrain bring quick weather changes.

Beneath the hill lies one of Britain's most extensive cave systems, including Ogof y Daren Cilau and Ogof Agen Allwedd. These underground networks remained hidden for millennia and are explored by cave researchers today.
