Clare meets a passionate proponent of walking today on a hike around Capel y ffin and the Twmpa in the Bannau Brycheiniog (Brecon Beacons) National Park. Andrew Green has just published a book called Voices on the Path, a History of Walking in Wales and for him it’s not just a case of putting one foot in front of the other and admiring the scenery, it’s “an activity loaded with all kinds of social, cultural and economic associations”. Their immediate surroundings have long attracted writers and artists from across the generations including William and Dorothy Wordsworth, JMW Turner, Bruce Chatwin and Allen Ginsberg. Also drawn to the beauty of Capel y ffin was the poet and painter, David Jones, described in 1965 as the 'best living British painter' by the then Director of the National Gallery. Peter Wakelin's book 'Hill Rhythms' tells Jones' story, which he wanted to share with Clare on the walk but a twisted ankle meant he had to remain at base, however he used the time to seek out the potential location of one of Jones's best loved paintings.They met at the tiny Capel-y-ffin chapel on the Monmouthshire/Powys border and walked up the Twmpa - also known as Lord Hereford’s Knob - in the Black Mountains returning via the valley of Nant Bwch. A walk of just over six miles. Grid Ref for where they met: SO253316Presenter: Clare Balding Producer: Karen Gregor
