Oslo has an efficient public transport system with an extensive network of buses, trams, underground trains (T-bane) and ferries. In addition to single-trip tickets, day and transferable eight-trip tickets are also available. Children aged four to 16 and seniors over 67 years of age pay half price on all fares.
The Oslo Pass includes access to all public transport options within the city, with the exception of late-night buses and trams. Bicycles can be carried on trams and trains for an additional Nkr11. The automatic fine for travelling without a ticket is a rather punitive Nkr750.
Trafikanten (177; www.trafikanten.no; Jernbanetorget; 7am-8pm Mon-Fri, 8am-6pm Sat & Sun) is located below Oslo S tower and provides free schedules and a public transport map, Sporveiskart Oslo.
Ferries to the Oslofjord islands sail from Vippetangen Quay.
The express boat Princessin (22 87 64 20; www.nbds.no) connects Oslo with Drøbak (Nkr72, 1½ hours, three weekly) and other Oslofjord stops en route: Ildjernet, Langåra and Håøya (which is a holiday spot offering fine swimming and camping). It departs from Aker Brygge pier.
Oslo has its share of one-way streets, which can complicate city driving a bit, but the streets are rarely as congested as in most European cities.
Metered street parking, identified by a solid blue sign with a white ‘P’, can be found throughout the city. Payment (up to Nkr44 per hour) is usually required from 8am to 5pm Monday to Friday, and until 3pm Saturday. At other times, parking is free unless otherwise posted. The city centre also has 16 multistorey car parks, including those at Oslo City and Aker Brygge shopping centres; fees range from Nkr70 to Nkr200 per 24-hour period.
Note that the Oslo Pass includes parking at all municipal car parks; instructions for display come with the pass.
Bus and tram lines lace the city and extend into the suburbs. There’s no central local bus station, but most converge at Jernbanetorget in front of Oslo S. Most westbound buses, including those to Bygdøy and Vigeland Park, also stop immediately south of the National Theatre.
The frequency of service drops dramatically at night, but on weekends, night buses N12, N14 and N18 follow the tram routes until 4am or later; there are also weekend night buses (201 to 218). These services are called Nattlinjer and cost Nkr45 per ride (no passes are valid).
Tickets for most trips cost Nkr20 if you buy them in advance (at 7-Eleven, Narvesen, Trafikanten) or Nkr30 if you buy them from the driver. A day pass costs Nkr60.
Flagfall starts from Nkr39 plus Nkr12 to Nkr18 per kilometre. There are taxi stands at Oslo S, shopping centres and city squares, but any taxi with a lit sign is available for hire. Otherwise, phone Norgestaxi (08000) or Oslo Taxi (02323), but note that the meter starts running at the point of dispatch! Oslo taxis accept major credit cards.
The best place to rent bicycles is the Skiservice Sykkelutleie (22 13 95 04; www.skiservice.no; Tryvannsveien 2; per day around Nkr295) in the Nordmarka. To get there by public transport take T-bane 1 towards Frognerseteren and get off the Voksenkollen station (the 2nd-last stop).
One alternative if you don’t plan on going too far is Oslo Citybike (22 02 34 88), a network of bikes that cyclists can borrow for up to three hours at a time from bicycle stands around the city. Access cards (Nkr70) can be purchased from the tourist office and last for 24 hours, but bikes must be exchanged or returned to a rack within three hours or you will loose your deposit (Nkr500). They’re convenient and well maintained; just don’t forget to get a map of the bike stand locations around the city, as the rack you were planning to use may be full.
