Bicycle
Oslo City Bike (www.oslobysykkel.no) gives you unlimited rides of 45-minute duration over 24 hours (49kr) from bicycle stands around the city. You can buy a pass via the website or its smartphone app. The bikes are convenient and well maintained but are only available from 6am to midnight and only in the ‘ice-free’ season (generally from April to November).
Boat
Ferries to the Oslofjord islands sail from Vippetangen Quay. The Bygøy Ferry (every 30 minutes, mid-March to mid-October) leaves from Rådhusbrygge Quay for the cluster of museums on Bygøy.
A good number of the inner-island ferries are covered by the Ruter network too.
Bus
Bus lines lace the city and extend into the suburbs and services are reliable. There’s no central bus station for local routes, but most buses pass through Jernbanetorget in front of Oslo S. Most westbound buses, including those to Bygdøy and Vigeland Park, also stop immediately south of the National Theatre.
A handful of bus routes run a 24-hour service, but service frequency drops dramatically at night. A network of night buses fill in the gaps to run a skeleton service in the wee hours.
Car & Motorcycle
Oslo has its share of one-way streets, and is introducing no-parking zones within the city centre, which can complicate city driving. That said, the streets are rarely as congested as in most European capital cities. Metered street parking, identified by a solid blue sign with a white ‘P’, can be found throughout the city. Payment is usually required from 9am to 8pm Monday to Saturday. At other times parking is free unless otherwise stated.
Taxi
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 or Oslo Taxi, but note that the meter starts running at the point of dispatch and they are definitely not cheap. Oslo Taxis accept major credit cards.
T-Bane
Oslo’s Tunnelbane system isn’t huge, but it’s easy to navigate and links up most major sights. All T-bane lines pass through the Nationaltheatret, Stortinget and Jernbanetorget stations.
Tram
The city has six tram lines, all of which stop at Jernbanetorget (for Oslo S). Services run every 10 to 15 minutes during the day, and around every 20 minutes early mornings and in the evening.
