Tucked above the Arctic Circle, Tromso puts on a wintertime display of northern lights swirling across the sky. Come summer, darkness disappears as the city glows with the midnight sun. But whatever the season, you'll be spellbound by the city's cute fishing villages, gushing waterfalls, and narrow fjords. Music is a major part of the Tromso culture, so join the locals at a concert in the Arctic Cathedral or dance to techno and electronica at the annual Insomnia Festival.
