The town also fosters tourism by offering snowmobile tours, trekking, skiing, fishing and dogsled rides. If things go to plan, Arvidsjaur will be the location of the front legs of the world's biggest moose - Stoorn - a tourist attraction to be built from Arvidsjaur to Skellefteå in Västerbotten.

Arvidsjaur has a subarctic climate that is dominated by the long winters and briefly interrupted by moderately warm but very bright summers due to its northerly latitude.
