Crystal Serenity, Northern Europe
While cruising the Baltic Sea, voyagers will have a chance to discover the countries that make up the region. Crystal guests will explore Stockholm’s charming lanes, Tallinn’s medieval splendour, the historic riches of Hamburg, and St. Petersburg’s gilded palaces. They will discover Berlin’s majestic Brandenburg Gate and experience the charm of Warnemunde, gateway to the rich history of Berlin. And fairytale-lovers won’t want to miss seeing Copenhagen’s Little Mermaid.
