Oslo Gardermoen (OSL) is 47 kilometres north of the city with a railway station under the terminal. It is Norway’s main hub and it is efficient.

Before you book

Check which airport. Torp (TRF) is marketed as “Oslo Torp” and is at Sandefjord, 110 km south — around two hours from central Oslo. A cheap fare into Torp is often not cheap once the transfer is added.

Airlines. Norwegian, SAS and Widerøe are the domestic and Nordic operators. Most European carriers serve Gardermoen, and there are long-haul services to North America and Asia, though fewer than from Copenhagen or Stockholm.

Getting in. Flytoget in 19 minutes or the ordinary Vy train in 23, on the same track to the same platform, for about half the price. See Oslo Airport to the city.

Use the arrivals duty-free

This is genuine practical advice, not a joke.

Norway’s alcohol is sold through the state monopoly at prices that startle visitors. Gardermoen has a duty-free shop in arrivals, before customs, and Norwegians returning home queue at it.

Know your allowance — there are quantity limits and they are enforced, with a calculator on the Norwegian customs site.

Entry

Norway is in the Schengen Area but not in the EU. No border checks arriving from another Schengen country; full checks from outside.

Customs is separate from immigration. Arriving from an EU country still means going through Norwegian customs, and the alcohol and tobacco limits apply.

ETIAS, the EU travel authorisation for visa-exempt visitors, applies to Schengen including Norway; check whether it affects you.

When to fly

Cheapest: January, February and November.

Most expensive: the 17 May weekend, the March ski festival, and the Christmas period.

Best: June for the light, February for the snow. See when to go.

Getting on elsewhere

The Bergen railway — seven hours across the Hardangervidda — is one of the great train journeys in Europe and is a better way west than flying.
