This time, Julia takes a bracing coastal hike along 7.5 miles of the wild Lizard Peninsula, Cornwall’s most southerly point, starting at the much-photographed Kynance Cove and finishing at the idyllic fishing village of Cadgwith. Along the epic and scenic coastline, she learns about Serpentine Rock, visits a hut that changed the course of modern technology and gets a pasty-making masterclass.
