The Alta Museum at Hjemmeluft houses the largest collection of prehistoric rock carvings in northern Europe, dating back some 6,000 to 7,000 years. The outdoor trail along the shoreline of the Altafjord follows a 3-kilometre path past thousands of individual carvings depicting reindeer, bears, fishing boats, humans, and hunting scenes — all etched into the smooth rock faces at the water's edge by Stone Age and later Bronze Age peoples.
The museum building itself does a good job of contextualising the carvings, with exhibits on Sami culture, the natural history of Finnmark, and the gradual discovery of the art (the first carvings were found in 1973). Allow at least two to three hours for the full outdoor trail. The site is open year-round but the path can be icy in winter — wear appropriate footwear.
