From the Airport
There are three conventional ways to get from the Oslo airport to the city center. The high speed airport express train, Flytoget, is by far the easiest method and takes under twenty minutes to reach the city. Trains depart every ten minutes with a standard cost of 200 NOK that can be reduced based on mode of payment and age.
Numerous bus routes also leave from the airport to the city, making this an attractive option based on your desired destination. Buses to Oslo’s city center are operated by Flybussen and take around forty-five minutes to reach the city. Tickets cost 140 NOK and round-trip tickets (valid for one month after purchase) cost 240 NOK. There is an information stand at the airport that can provide information about all bus services leaving the airport.
The final (and least recommended) option to get to Oslo is to order a taxi. Taxis should be ordered from the booth inside the airport. Fixed rates begin at 700 NOK, but can be even more expensive. Taxis are even more costly if you flag them from the queue outside of the airport. If you need to get to a particular destination, your best bet is taking the express train or bus to the city center and then taking a cab from there.
