York

On a 15-mile walk in North Yorkshire, Kate sets off from the picturesque settlement of Robin Hood's Bay, where archaeologist Maria explains how, in the 18th century, the fishing village's position made it an idea drop-off point for contraband shipped from Holland and France. From here, Kate heads south along the coast, meeting up with geologist Will, who reveals what dinosaur footprints can reveal about the creatures that once roamed the area. After arriving at her destination in Scarborough, Kate dons her wetsuit to join a group of swimmers braving the North Sea.
