Getting to Oslo from Oslo Airport
The easiest way to get from Oslo Airport to downtown Oslo is by train.
After passing through baggage claim and customs, follow the signs to the train station. You can either ride the more frequent (and more expensive) Airport Express, or the less frequent (and less expensive) NSB train (lines R10, R11, L12). Get off at Oslo Central Station (Oslo sentralstasjon).
The NSB trains and some Airport Express trains also stop at the National Theatre station (Nationaltheatret), which is closer to CAS and may be closer to fellows' accommodation in Oslo.
Oslo is served by a number of different public transportation options: bus, ferry, metro, train, and tram. The system is operated by the common management company Ruter.
Physical tickets and reusable travelcards are also available for purchase at most metro stops and at sales outlets around the city.
Note: If you purchase a reusable travelcard, remember to activate it by touching it to one of the validators located on the platform (if riding the metro) or on board (if riding buses and trams). You need only do this once.
Single-ride tickets can be purchased on board buses, ferries, and trains, but for an additional surcharge. Tickets are not sold on board trams and metro trains.
The public transportation system in Oslo runs on the honour system, but there are frequent ticket inspections. Passengers who fail to produce a valid ticket during an inspection will receive a fine.
The easiest way to get to CAS is by tram. Take tram line 13 in the direction of Bekkestua or Lilleaker, and get off at Skarpsno.
Oslo City Bike operates bikeshare stations around Oslo. The system is generally open from April to November, or whenever roads get too icy. Bikes are unlocked by using a smartphone app.
