The naturalist enjoys an 11-mile walk in Exmoor along the South West Coast Path, regarded as one of the most beautiful such paths in the world. Starting at Porlock Weir, Kate heads to St Bueno’s, a tiny parish church that seats just 33 worshippers – and which holds a dark past. She then heads inland to see the valley that inspired RD Blackmore’s 1869 novel of outlaws and revenge, Lorna Doone. At Lynmouth, Kate rides the world’s highest and steepest water-powered railway, before finishing her walk seemingly on top of the world in the Valley of Rocks.
