Osen is Trøndelag’s fjord-fringed solitude basin - a municipality where whales are carved into coastal rocks, fishing nets shimmer on the coat of arms, and burial cairns whisper stories from 1904. With around 900 residents and a landscape shaped by the Steinsdalen valley, Vingsand coast, and the villages of Osen and Seter, Osen is the kind of place where you can hike past petroglyphs, explore 19th-century farmsteads, and still catch a lighthouse view beside a WWII satellite prison site. It’s got quiet, quirk, and a name that means “mouth of the river.”

Where to Stay in Osen
Getting There
Osen lies on the Fosen peninsula, bordered by Flatanger, Namsos, and Åfjord. The E6 highway doesn’t reach it directly, and the northern part of the municipality has no road connection to the south - but ferries and scenic drives make it worth the detour. The area is best explored by boots, boat, or bold curiosity - especially if you’re chasing whale carvings, lighthouse lore, or the hush of birch leaves beside a burial cairn.
