Karlsøy

Karlsøy is Troms’ island constellation - a municipality where puffins nest on cliffs, cloudberries ripen on mountaintops, and reindeer graze beside psychedelic music festivals. With around 2,200 residents and a landscape shaped by 600 islands, sea spray, and Sámi folklore, Karlsøy is the kind of place where you can kayak past lighthouses, hike to WWII hideouts, and still catch a joik concert in a wharf café. It’s got edge, echo, and a name that once meant “Karl’s island.”

Getting There

Karlsøy sits north of Tromsø, with Hansnes as its administrative center. The Rv863 highway and undersea tunnel connect to Tromsø, and ferries run to Vannøya, Reinøya, Rebbenesøya, and Karlsøya. The area is best explored by car, boat, or boots - especially if you’re chasing puffin calls, festival vibes, or the hush of moss under midnight sun.
