Tip #3 - Ferries to Djurgården
Stockholm is made up of 14+ islands and sometimes, looking at a map, it can seem hard to get from point A to point B without a long journey around half the city. Fortunately there are a few ferries that make travelling much easier. Of special note is the Djurgårds Ferry (Djurgårdsfärjan) which transports people between Slussen, on the south-end of the Old Town (a 10 minute walk from the Rival Hotel), and the islands of Djurgården and Skeppsholmen. This is especially useful as many of the main tourist attractions are located on these islands. On Djurgården you will find Skansen, the Vasa Museum, Nordic Museum among other attractions. On Skeppsholmen you have both the Modern Art Museum and Museum of East Asian Antiquities.
The boats leave approximately every 15 minutes year round and the trip takes approximately 8 minutes. During the summer the boats operate all day late into the evening. Tickets can be bought at the booth before you board (40 SEK adults, 25 SEK children/seniors); some SL bus/subway cards do work though not the strips or one-time tickets. Remember to get off on the right island!
