Starting in Dorset on Stonebarrow Hill, the naturalist walks a 13-mile stretch of the South West Coast Path. Her first stop is at Charmouth, a place well-known for fossil hunting, where local girl Mary Anning found an ichthyosaur in the early 19th century. At Lyme Regis, Kate discovers the lengths and costs engineers have gone to in order to protect the town, before visiting a local mill listed in the Doomsday Book. After a spell bird spotting in the Seaton Wetlands, Kate enjoys a tour of the area's limestone mines before making her way to Beer Point, which boasts wonderful views of the sea.
