Trains, busses and airports in Sweden
There are international airports all over Sweden. In Stockholm the airport is called Arlanda and in Gothenburg it is called Landvetter. The train system is wide and easily accessible. Travelling to Sweden you can also come by train or car from Norway or Finland. If you are coming from other parts of Europe you access Sweden through Denmark, either crossing the Öresund Bridge from Copenhagen to Malmö or taking the ferry from for example Helsingør to Helsingborg or Rostock to Trelleborg.
Trains: SJ
The train system is wide, easily accessible and comfortable. For example going from Malmö to Stockholm by train takes approximately four hours, from Gothenburg to Stockholm takes about three hours. Since the country is so wide though, going from the farthest north to the farthest south, you can spend a good 24 hours on your train.
Unfortunately the prizes are rather high and they change with the date. So the sooner you book the tickets, the less expensive they are. But there are discounts for children, youth (16-25), students and seniors.
