Julia heads to Isles of Scilly, an enchanting archipelago of wild islands in the Atlantic Ocean. Walking a five-mile circular loop around St Martins, an island renowned for its white sand beaches and azure seas, Julia discovers what is believed to be the oldest beacon in Britain, visits a rum distillery and harvests seaweed on a windswept beach.

Finally, Julia finishes her island adventure with a hop to Tresco, where she visits the Abbey Gardens, world famous for its sub-tropical plants.

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.
