Known for its river cruises, CroisiEurope also offers ocean voyages on two small ships. Guests boarding the 130-passenger La Belle des Oceans (formerly Silversea's Silver Discoverer) can follow in Napoleon's footsteps, visit the hilltop villages of Balagne, and enjoy dinner at a traditional inn. Meanwhile, the 197-guest La Belle de l'Adriatique offers itineraries that take in local traditions.
