Kate Humble's Coastal Britain

Dover (3x3)

Air date: Apr 15, 2022

Kate follows the iconic white cliffs of Dover on a 15-mile walk of contrasts. As well as overlooking the busiest shipping lane in the world, this route contains one of the world's rare rivers - a chalk stream flowing through the heart of Dover. Kate's walk begins above Folkestone Harbour at Martello Tower 3, built in the early 19th century to defend against a naval invasion by Napoleon.
