The largest part of Sápmi lies north of the Arctic Circle. The western portion is an area of fjords, deep valleys, glaciers and mountains, the highest point being Mount Kebnekaise (), in Swedish Lapland. The Swedish part of Sápmi is characterized by great rivers running from the northwest to the southeast. From the Norwegian province of Troms and Finnmark and eastward, the terrain is that of a low plateau with many marshes and lakes, the largest of which is Lake Inari in Finnish Lapland. The extreme northeastern section lies within the tundra region, but it does not have permafrost.
