By air: The Gardermoen International Airport (IATA designator "OSL") offers excellent access to destinatons around the world. It is one of Scandinavian Airlines' international hubs, and is also served by several foreign carriers (including Air France, British Airways, Finnair, Icelandair, KLM, Lufthansa, LOT Polish Airlines and many more). The modern, elegant airport is located approximately 50 km north of downtown Oslo, but is easily reached by freeway, airport buses, or by Flytoget, a 20-minute bullet-train to downtown. (To downtown, the train is NOK 125 each way; the bus takes 40 minutes but costs less, NOK 65). Visitors leaving on early flights may wish to stay overnight at the airport hotel, which has direct access to the terminal building.
To the southwest of Oslo, the smaller Torp International Airport, located in the town of Sandefjord, often offers cheaper fares, in part because low-fares carrier Ryanair flies there (other carriers are KLM, Widerøe, Coast Air and a number of Charter Operators). The airport is located 120 km south of downtown Oslo, and services a number of other communities along the Western side the Oslo Fjord. It can be reached by airport buses (2 hrs) and local trains. Note: Torp airport handles limited domestic traffic. If you are connecting to other airports in Norway, chances are you must arrange for your own travel for the 175 kilometers from Torp to Gardermoen (by bus or train).
By boat: Oslo has ferry connctions to Copenhagen and Fredrikshavn (12 hrs) in Denmark and Kiel in Germany. The ferries are large and comfortable and offer TaxFree shops, Restaurants, Bars, and Danceclubs. They are quite popular with Norwegians, who board them for weekend trips to Denmark and Germany.
By Rail: From the Oslo Central Station ("Oslo S"), trains to Europe travel South-East along the Oslo Fjord, into Sweden. The Linx (www.linx.no) high speed train services link Oslo to Stockholm, Gothenburg and Malmö in Sweden, and Copenhagen, Denmark.
Within Norway, all trains are operated by the Norwegian State Railroads ("NSB") (www.nsb.no).
Fjord Tours (www.fjord-tours.no) offers many great sightseeing trips of Norway that, conveniently, can be purchased at the Gardermoen airport and the Oslo Central Station, among other places. Tours such as "Norway in a Nutshell" use a combination of Rail, Express Boat, Coastal Steamer, and Buses to take you to the spectacular mountains, fjords, and towns in Norway. You are generally permitted to choose dates, length of stopovers, and direction of travel with no surcharges. The tours are competitively priced, but note that you must purchase your overnight accommodations separately (the Fjord Tours pass entitles you to a discount at many hotels).
By car: A series of large construction projects completed near the end of the 20th century has reduced driving times to Central Europe from Norway and the Scandinavian Peninsula. Almost all trips will go through Sweden, with which Norway shares most of its borders. Copenhagen is under 7 hours away (just over 600 km); Stockholm about the same travel time (about 530 km; but not very much as freeway); Berlin about 12 hrs including ferry between southern Sweden and Germany (about 830 km).
