Tips
Twyn Llech (703m), also known as Black Mountain, is the only Marilyn to fall exactly on the Welsh–English border, straddling Brecknockshire (Powys) and Herefordshire.
The Black Mountain is the highest point on the Hatterrall Ridge, with Offa's Dyke Path passing along the ridge.
Because of the very shallow gradients along the summit ridge it's virtually impossible to determine the actual high point by sight.
The ground is peaty and normally very wet even in good weather, especially on the highest ground.December 22, 2022
Although only 740 meters (2,428 ft) high, the wind gets pretty tough here. One feels like in the mountains.
