This week, Julia's journey reaches the Sporades. Known as the ‘Paradise Islands', their lush pine forests and breathtaking coastlines are recognisable to millions as the backdrop of the movie Mamma Mia. On Skiathos, Julia boards a fishing boat in search of a secret world of hidden coves and deserted beaches, sampling the local delicacy of sea urchins, hand-dived from the island's crystal clear waters. Heading inland, she visits the hillside monastery of Evangelistria, one of Greece's most important religious sites, before island-hopping to neighbouring Skopelos to witness a taste of marriage, Greek style. After trying on the island's traditional wedding dress, her trip ends at the tiny Chapel of St John, the setting for the final scene of Mamma Mia and one of the most spectacular locations in Greece.
