There are direct international scheduled flights from these cities to Trondheim:
Copenhagen, Amsterdam, Praha, London, Murcia, Alicante, Dubrovnik, Stockholm. There are charter flights to many other places in southern and eastern Europe. Getting to and from Trondheim is a breeze.
If travelling from an international destination and need to transit before Trondheim, try to do it in Copenhagen. Try to avoid Oslo Gardermoen (OSL) and it's abysmal baggage handling in transit. Trondheim is a very small and convenient airport - despite it's location in the community called Hell!
The Airport of Trondheim Vaernes is connected with Oslo and all the main Norwegian towns with SAS Braathens and Winderoe. In the departure lounge you can see a very interesting show about the history of the airport and flying in the town of Trondheim.
During the summer season is very common to see charter fly to come from all Europe.
It depends on how you are travelling. Trondheim is easily accessible whatever your choice of transportation. There is an airport at V?rnes (around 30km from the city) or you can travel by train or car. Another special way to visit Trondheim is by the coastal steamer (Hurtigruten).
The city centre is best explored on foot, however all the bus routes have stops in Munkegata and Dronningens gate in the centre of the city.
Vænes Airport is just 35km NE of Trondheim and has two SAS flights daily from Copenhagen. There are 40 flights daily to Oslo.
The airport bus runs every 15 minutes to downtown Trondheim.
