The easternmost section of the national park centres on the Black Mountains, far quieter than the central belt of the Brecon Beacons and skirted by the wide valley of the River Usk to the south and the Wye to the north. The only exception to the Black Mountains’ unremitting sandstone is an isolated outcrop of limestone, long divorced from the southern belt, that peaks north of Crickhowell at Pen Cerrig-calch (2302ft). The Black Mountains have the feel of a landscape only partly tamed by human habitation: tiny villages, isolated churches and delightful lanes are folded into an undulating green landscape that levels out to the south around the village of Crickhowell.
