Tivoli is a huge funfair on Djurgarden island, opposite the main Skansen entrance, with great views across to Gamla Stan and Sodermalm. The entry prices are a bit cheeky, as you pay to get in, only to find everything costs extra. If you have a Stockholm or Tourist card, however, initial entry is free. #
Tivoli isn't a particularly classy, or clean establishemnt but it makes for an exciting end to a Djurgarden day trip - a 180kr evening wristband gets you on all the decent rides between 7pm and midnight, when the park empties out and queues are short. Go on half a dozen rides, in particular the impressive Jetline, and it's value for money.
Get to Djurgarden via the 44 and 47 buses from Sergel Torg, the No. 7 tram from Ostermalm, or the ferry from Slussen. All journeys are free with the 72hr Tourist Card.
