Iolo's Borderlands

Episode 2 (1x2)

:

Iolo Williams explores the borderlands of the old county of Radnorshire. He begins his journey along the banks of the Wye between Hay-on-Wye and Glasbury, where he discovers nesting little-ringed plovers and oystercatchers. Further upriver at Llyswen, he finds spawning sea lampreys - extraordinary metre-long jawless fish.
