Located 400km north of the Arctic Circle at 69˚N, the small city of Tromsø bills itself as Norway's gateway to the Arctic, and there's definitely more than a hint of polar atmosphere around town. Surrounded by chilly fjords and craggy peaks that remain snowcapped for much of the year, Tromsø sits on the eastern edge of Tromsøya, and is linked to the mainland by a gracefully arched bridge.
