With its open-aired piazzas, flower-filled balconies and tumbling hills, Sorrento has been sending out its siren's call for centuries. But neither Roman emporers nor writers such as D.H Lawrence have been able to resist jewel-like Capri, which lies a hydrofoil ride away in the Bay of Naples. From Sorrento you can also drive along the beautiful Amalfi Coast to the eerie remains of Pompeii.
