Pen y Fan

The route continues on the west-to-east Brecon Beacons Way, now over halfway to its final destination at Abergavenny Station. This is possibly the most strenuous day's walking as there are a number of climbs, starting with Corn Du and Pen y Fan. However, on a clear day, the views are spectacular.

This Powys walk starts from Cwmgwdi and visits Corn Du passing the monument to the Lost Lad before continuing to Pen y Fan, the highest point in the Brecon Beacons National Park. Continuing, the walk then visits the summits of Cribyn and Fan y Big before returning to the start along the western side of Cwm Cynwyn.

This trail leads you to Sgwd-yr-Eira, Sgwd y Pannwr, Sgwd Isaf Clun-Gwyn and Sgwd Clun-Gwyn.

The route goes from YHA to YHA but essentially follows the Brecon Beacons Way going west-to-east. This section goes through a Site of Special Scientific Interest as it passes Llangorse Lake (Lyn Syfaddan). Formed in the Ice Age, it is one of the few naturally eutrophic lakes in Wales and is of national if not international importance.

We're now well into the Brecon Beacons Way and this route begins with a walk through the Ogof Ffynnon Ddu National Nature Reserve, designated to protect its limestone pavements, associated flora and caves beneath. Then it heads north to climb up to Fan Llia and follow the crags over to Storey Arms. It then takes the Taff Trail to YHA Brecon Beacons.

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.

The route leaves Llanddeusant and heads into the Black Mountains on the third leg of the Brecon Beacons Way. It's generally a walk south along ridges and mountain tops to finally drop down to the Craig-y-nos Country Park on the Afon Tawe river.
