The lake also supports a diverse range of aquatic life.

Along the shores of Mjøsa, several towns and cities are located, including Hamar, Gjøvik, and Lillehammer, the latter being famous for hosting the 1994 Winter Olympics. The scenic beauty of Mjøsa and its surrounding landscape attracts tourists, and recreational activities such as boating, fishing, and swimming are popular during the warmer months.
