3Trondheim, Norway

Located on the fjord of the same name, Trondheim is Norway’s third largest city.

However, with fewer than 200,000 residents, it’s decidedly uncrowded and easy to explore. The famous Gothic cathedral is perhaps its best known sight, but the views across the water and around its vibrant harbor are just as impressive.
Trondheim is also known for its excellent microbreweries — Den Gode Nabo is popular and a great place to start.
