Twyn Llech also known as Black Mountain is a mountain in the Black Mountains (not to be confused with the Black Mountain range of hills some 45 km or about 30 miles to the west, or the Black Hill just 2 km or about a mile east). It is the only Marilyn to fall exactly on the Welsh-English border, straddling Powys and Herefordshire. Its parent peak, Waun Fach lies to the west.
The Black Mountain is the highest point on Hatterrall Ridge. Offa's Dyke Path passes along the ridge, more or less from south to north, while a steeper path leads to the summit from near the former youth hostel in the Vale of Ewyas to the west. The summit is unmarked and, because of the very shallow gradients along the summit ridge, virtually impossible to determine in situ.
It is the highest ground in England south of Great Whernside in the Yorkshire Dales,[1] even though higher neighbours are very close by in Wales. However, some mountain lists, such as the Nuttalls, consider the mountain belongs only to Wales, due to the Black Mountains range being principally a Welsh massif.[2]
