Located in south-eastern Finland, Lake Saimaa is Finland’s largest lake, covering around 4,400 km² (some 1,660 mi²). It is a vast network of interconnected waterways, islands, rocky shores and forests formed by glaciers. The lake is surrounded by towns such as Savonlinna, Lappeenranta and Mikkeli.
Lake Saimaa is famous for the Saimaa ringed seal, found only in this lake system. With an estimated population of around 530 individuals in 2025, it remains one of Finland's most endangered mammals. The Saimaa salmon – a rare native fish – is another endangered species to be found in the Lake Saimaa water system.
The surrounding forests also provide habitats for a wide range of mammals (moose, roe deer, otters, beavers, foxes, squirrels and pine martens) and birds (including ospreys, white-tailed eagles, loons, herons and numerous species of waterfowl and woodland birds).
The lake is ideal for boating, canoeing, kayaking, fishing and swimming. Wildlife watching enthusiasts come particularly for the Saimaa ringed seal and for birds. Numerous trails around the shoreline are suitable for walking and cycling, while boat cruises offer a way to explore the islands and waterways. In winter, the frozen landscape is popular for cross-country skiing, snowshoeing and ice fishing.
Lake Saimaa can be reached from several towns in south-eastern Finland, with Lappeenranta and Savonlinna being popular bases for exploring the region. Visitors can travel by train, bus or car from Helsinki, with boats and local tours providing access to the lake itself.
