Enjoy the landscapes of the Brecon Beacon National Park and the Wye Valley Area of Outstanding Natural Beauty as you walk southwards from Knighton, home to the Offa's Dyke Centre. On your journey you'll ascend the highest part of the trail on the Hatterrall Ridge crossing the Black Mountains and follow riverside trails along the River Wye; explore the 'town of books' Hay-on-Wye and enjoy views to Tintern Abbey from Devil's Pulpit. Discover the historical sites of Monnow Bridge, White Castle and Chepstow Castle and look out for some spectacular birdlife - dippers and kingfishers on the rivers and red grouse on the heather moorland of the Black Mountains.
