Stockholm is often praised for its comfortable, efficient and safe transportation. Stockholm Public Transport, SL, is responsible for buses, underground trains, commuter trains, trams and certain ferry lines in Greater Stockholm.
The underground is the easiest way to get around town. The city is divided into three zones, and zone tickets are good for several trips within the hour. Tickets can be purchased at SL Centers, underground platform barriers, newsagent kiosks or via SMS. It's not possible to pay cash for tickets on board buses in Stockholm. Most bus stops have ticket machines that take both coins and cards.
Prepaid cards are the best alternative for those making few trips. It's also possible to buy 1, 3, or 7-day cards, which allow free travel in all zones during the validity period. Another alternative is the Stockholm Card, which allows free travel and free entry to 80 museums and attractions in the city. Stockholm Cards are valid for 24, 48 or 72 hours.
A trip on the number 69 bus or number 7 tram is a superb way to discover Stockholm. The lines go out to Djurgården and major attractions like Skansen and the Vasa Museum.
Stockholmers are always heedful of their beautiful surroundings, and this has led to many inner city buses running on eco-friendly fuels such as ethanol. The Stockholm underground is also known as the world's longest art gallery as so many of its stations are adorned with the works of different artists.
