Start your voyage in the ancient Greek city of Athens, home to the Acropolis, the Plaka, and the Parthenon.

Arrive in Constanta, a coastal resort town, en route to Bucharest and Dracula’s Castle. Enjoy a late night in sparkling Odessa, with time to visit its beaches and climb the lucky Potemkin Stairs. In Sochi, home of the 2014 Winter Olympics, visit Sochinskiy National Park. Stroll the beach promenade and piazza in the popular resort town of Batumi, Georgia before exploring one of the loveliest towns on the Black Sea coast, the walled city of Sinop, Turkey. An overnight in Istanbul affords time to see the Blue Mosque, Hagia Sophia Museum, the Grand Bazaar and sip a tiny cup of potent Turkish coffee with sweet lokum (Turkish delight). Transit the narrow Corinth Canal to experience Delphi’s Temple of Apollo and Archaeological Museum. Savor a late night in Dubrovnik with time to explore Old Town and watch divers leap off the cliffs into the Adriatic. The approach to Kotor, Montenegro offers breathtaking fjord-like views while the car-free medieval town awaits. In Zadar, Croatia witness the haunting Sea Organ performed by the surging Adriatic. Situated on a tiny piece of land jutting into the sea, Piran, Slovenia boasts medieval architecture, narrow streets, and Skocjan Caves National Park. For the grand finale, overnight in Venice with time to wind around the canals and fully appreciate St. Mark’s.
