Northern Norway (Nord-Norge) is Europe's northernmost region mostly north of the Arctic Circle. Northern Norway has an endless and very rugged coastline, yet landscape varies from incredible jagged island mountains to endless open plateaus. Summers have non-stop daylight (and midnight sun) while during the darker season there is frequent display of northern lights (aurora borealis). Northern Norway covers 50% of Norway's area but is generally sparsely populated with only 10% of Norway's population.
