Derek Brockway returns with a new series of walks around Wales, starting with two easily accessible rambles at either end of the country. Derek's first walk starts at the seaside village of Moelfre on Anglesey accompanied by writer and TV producer Bedwyr Rees. The walk follows the coastal path looking at sites of dramatic shipwrecks and hearing about the rescues by heroic local lifeboatmen. Going inland Derek discovers some remains of the island's ancient and bloody past. The second walk picks up this historical theme in the countryside around Dyffryn Gardens in the Vale of Glamorgan. Derek's guide is Will Renwick, who at 22 became the youngest person to walk the whole perimeter of Wales. The walk is gentler but takes in extraordinary burial chambers, a pretty church and some dazzling dahlias at the recently restored Dyffryn Gardens.

Derek Brockway tries out barefoot walking in the hills above Crickhowell with Lynne Allbutt - the first person to run barefoot across Wales. And following that theme, he walks around Lake Tegid at Bala - the biggest lake in Wales - partly on the route of Mari Jones, who back in 1800, walked 25 miles barefoot to buy a copy of the Bible in Welsh.
