Wave goodbye to Rome as we set sail from Civitavecchia on a short tour that ticks off four countries – Italy, Greece, Montenegro and Croatia. Sorrento is our first port of call, heady with the scent of its lemon trees, then Siracusa on Sicily, to explore the delightful old town, with its ancient Greek and Roman ruins. Now relax and enjoy all our ship has to offer as we head to Greece and the lush, green island of Corfu, where there is good walking along the pine-fringed cliffs. Next Montenegro and the labyrinthine fortress town of Kotor, then Zadar on Croatia’s Dalmatian coast with its curious Sea Organ, a sound installation on the waterfront designed to let the waves to play music. We return to Italy now, for an overnight in Ravenna, an unsung city, yet home to eight Early Christian monuments that have all been listed by UNESCO, before our final port, Fusina, gateway to Venice.
