This is a brilliant linear trail in the Brecon Beacons National Park, incorporating many good viewpoints and one extra-special one. It begins in Carmarthenshire near the village of Llandeusant and ends in Powys in the Glyntawe valley, crossing a mountain ridge that beats Pen-y-Fan in my view but because it's less accessible is less well-known. A GPS File is available for download (see walk description).
