On the Scottish Borders, Kate walks almost 15 miles from the historic fishing village of St Abbs to England's most northerly town, Berwick Upon Tweed. Her trek starts on St Abbs Head, from where she descends to St Abbs harbour, named after a Northumbrian Princess and Saint, Ebba, who was shipwrecked and founded a nearby monastery in the 7th century.

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.

Kate follows the historic East Sussex coastline, beginning on the cliffs overlooking Hastings, a town associated with the Battle of 1066. However, she is here to visit an equally historic fishing fleet that has operated from the town's ancient shingle beach, The Stade, for more than 1000 years.

The naturalist takes a wintry walk around the western corner of the Isle of Wight, where she holidayed as a girl. Starting on Yarmouth's wooden pier, her journey begins with a boat trip to the Needles, which her Victorian guidebook recommends as the best way to view these impressive chalk stacks.
