The approach to Sweden’s capital city of Stockholm, through the untouched nature of the archipelago, is breathtaking. Spread over 14 islands, Stockholm is called “The City That Floats on Water.” Not surprisingly, 57 bridges traverse the city. Start your tour at Djurgården, an island that was once the hunting grounds of the king and is now home to the fascinating Vasa Museum, housing the world’s only preserved 17th-century warship. Stockholm has 70 museums, including the world’s oldest open-air museum, the Skansen. Explore the narrow streets and medieval buildings of Gamla Stan, the Old Town founded in the 13th century. Stockholm also gives you access to three UNESCO World Heritage sites: the Viking outpost of Birka, the unique cemetery of Skogskyrkogården, and Drottningholm Palace, which has been home to the royal family since 1662.
