This day, sail along the Danube to Constanta, Romania, on the Black Sea coast. The oldest living city in Romania, Constanta was founded around 600 B.C. by Greek settlers, and is now a fashionable resort town. Arrive mid morning for a city tour featuring the iconic seaside casino and Art Nouveau architecture, and a stroll along Mamaia Beach, the “Palm Beach” of the Black Sea. Return aboard for dinner and evening cruising.
