Where and when to go

Seasons

This walk is exceptional in all seasons, though the Black Mountains and Clwydian range deserve respect in winter conditions, and especially in mist, since there are few landmarks on the Black Mountain ridge.

Centres

Chepstow, Hay-on-Wye, Kington, Bishops Castle, Montgomery, Welshpool, Oswestry, Llangollen, Denbigh, Prestatyn.

Difficulty

The trail includes a couple of unavoidably long stages, as well as some sections across mountains and moorland. However, it presents no particular technical challenges and is suitable for walkers of all abilities, provided that sensible advance planning is undertaken.

Must See

The route showcases a rich variety of landscapes and landmarks. Highlights include striking geological features such as the limestone gorge of the lower Wye, the igneous intrusions around Hergest Ridge, the dolerite formations of the Breidden Hills, and the limestone escarpments north of Llangollen. The upland sections take in the moorlands of the Black Mountain, the remote expanses of Clun Forest, and the Clwydian Ridge. In contrast, the lowlands offer gentler scenery, with orchards and meadows, the Montgomery Canal, and the broad Severn Valley. Along the way, there are also significant historical attractions, including Tintern Abbey and Llanthony Priory, a series of border castles, and the impressive Pontcysyllte Aqueduct.
