Braving the traffic, Michael begins his Roman holiday by weaving among the capital city's magnificent landmarks on the back of a 1950s Vespa. Following in the footsteps of early 20th-century British tourists, he pays homage to the romantic poets at the foot of the Spanish Steps before boarding the train south. Arriving in Naples, Michael savours spectacular views across the bay. He finds out about the first railway to be built in the country, from Naples to Portici, around the base of Vesuvius and then plucks up his courage to venture into the mighty volcano's crater.
