Regular British Airways flights to Oslo serve modern Oslo Airport, 30 miles north of Oslo city centre at Gardermoen. After your Oslo flight arrives, take the fast train service straight into the centre, and you'll quickly find yourself in your Oslo hotel. You can easily walk to most of Oslo's main sights, from the lively Aker Brygge waterfront to the graceful 19th-century Royal Palace and its manicured gardens.
After your flight to Oslo arrives, the quickest way to reach central Oslo is aboard the fast Oslo's Flight Train, Flytoget, which runs direct to Oslo Central Station from beneath the airport in under 20 minutes. The Oslo Airport Express (Flybussen) coach costs the same as the train, but takes twice as long. It can be handy if you're staying in Oslo's Majorstuen district, west of the centre. Oslo taxis, outside Flight Arrivals, are a pricier alternative, but useful if you have lots of luggage.
Once you're off your flight and in Oslo, you can begin to explore the compact city centre. Wander along Oslo's elegant Karl Johans Gate, with its smart shops and restaurants, and peek into the grandiose Royal Palace. Head across the Oslo Fjord to Bygdy Peninsula to see the beautiful 13th-century wooden stave church at the Norwegian Folk Museum. Before your homeward flights from Oslo, check out Oslo airport's huge duty-free shopping area, and pick up some smoked salmon or chunky Norwegian knitwear to take on your flight back from Oslo.
