Although Europe has been a leading travel destination for centuries, visiting this slice of the Old World never gets old. It's no wonder the continent is home to seven of the 10 most visited countries in the world. For novice vacationers, a first visit to Europe is akin to a rite of passage: the chance to experience tried-and-true destinations that never cease to charm and amaze. Experienced travelers, on the other hand, can still unlock less-trodden paths throughout the continent or rediscover familiar destinations in a different light. From the icy reaches of Arctic Norway to the sunny coasts of the Canary Islands, European cruise vacations offer a wide array of destinations in a relatively small geographical span. Itineraries focus on regions such as the Baltic Sea, with stops throughout Scandinavia, Russia, and the Baltic states; the British Isles; the North Atlantic; and the Norwegian Fjords. With so many historical sites, cosmopolitan cities, and breathtaking landscapes, your biggest challenge will be narrowing down which part of Europe to visit.
