Tromsø is surprisingly close. Fly directly from London, Riga, Murmansk and (in summer) Stockholm to Tromsø Airport, or connect effortlessly from around the world via Oslo Airport Gardermoen. Airlines like SAS, Norwegian, Air Baltic and Aeroflot compete by balancing service and punctuality with competitive fares.
Conference guests enjoying the luxury of time off may arrive in style by Hutigruten (The Norwegian Coastal Voyage), itself a conference venue.
The airport is a mere 10-minute drive from the city centre. City buses, an airport express bus and taxis can all take you into town.
