The best-known islands of the lake are Hautuumaasaari ("Graveyard Island"), which served as a cemetery for ancient Sami people, and Ukonkivi ("Ukko's Stone"), a historical sacrifice place of the ancient inhabitants of the area. There are over 3,000 islands in total. Trout, lake salmon, Arctic char, white fish, grayling, perch and pike are found in Lake Inari.
The lake covers 1,040 square kilometres (400 sq mi). It empties northwards through the Paatsjoki at the mouth of the Varangerfjord, which is a bay of the Barents Sea.
