The main cities in Sweden are well served by domestic flights using Scandinavian Air Services (S.A.S), and they operate flights at least once a day on major routes. The country also has an excellent high-speed rain network, which is almost as fast as flying.
Hiring a car is another option, but around sunrise and sunset, the roads do get invaded by plenty of reindeer, and you need to be cautious when driving in the dark.
Around any cities, taxis offer a safe and good value service. Women get a discount on taxis at night in order to keep the streets safer.
