The lonely 'Beacons road' high over Mynydd Epynt.
The B4520 climbs out of Builth Wells onto Mynydd Epynt, a vast, empty plateau of moorland used by the army, before dropping to Brecon. One of Wales's great undiscovered roads: fast, sweeping and utterly exposed. Heed the red flags and range signs, watch for sudden hill mist and sheep, and remember there's no fuel or support for miles over the top.
