Taxi: The trip takes about 10 minutes by taxi and costs around 300 NOK. The taxi stand is located directly outside the airport’s arrival hall.
Airport Express bus: Leaves from right in front of the airport and costs 125 NOK. You can find the schedule and pre-purchase a ticket here. Take the Express bus to the Scandic Ishavshotel stop. Your hotels are a few-minute walk from there. This bus also has a stop at the university (the stop is called UNN/UIT) if you are taking it directly from or to the airport. The timetable is available here.
Public transport: The trip takes about 20 minutes by public transport and costs 50 NOK in rush hour and 30 NOK in non-rush hour.
