Lake Inari is the second largest (1 153km2) in the world north of the polar circle. The surrounding mountains and its 3 000 rocky islands covered with pines and birches are reflected in its dark but pure waters, which don't thaw until mid-June. A Sami folk song, which has it that the lake is as deep as it is long, illustrates the respect the lake commands from the Sami. In actual fact, the deepest point of the 115km-long lake is 96m. Boat trips (June-October) leave from Inari for Ukonkivi, an island that was formerly a sacrificial site.
