Brecon Beacons Pass
A470Libanus to Trefechan
The high pass past the Storey Arms beneath Pen y Fan.
The A470 climbs over the central Brecon Beacons past the Storey Arms, beneath Pen y Fan and Corn Du, between Brecon and Merthyr. It is a fast, sweeping road across open mountain; watch for walkers crossing to the peaks, sheep on the carriageway and quick changes in the weather.
