Nat Park - Brecon Beacons

County/Area - Carmarthenshire & Powys

Author - Nigel Armistead

Length - 12.0 miles / 19.5 km

Ascent - 2000 feet / 606 metres

Grade - mod/hard

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 GPX File is available for download (see walk description).
