Lake Saimaa
The largest lake in Finland and the fourth-largest in Europe - a labyrinth of thousands of islands and the only home of the Saimaa ringed seal.

Illustrative image - a scene in the spirit of the place, not a photograph of it. Real photos are below.
Saimaa is the great lake of Finland, so broken by islands, peninsulas and channels that its shoreline runs to thousands of kilometres. It defines the eastern lake district, a world of summer cottages, wooden towns and quiet water, and it is the only place on earth the Saimaa ringed seal survives.
What you actually see
- The island labyrinth - endless forested islands and channels for boats and paddlers.
- The ringed seal - the endemic freshwater seal, seen best in the Linnansaari area.
- Lakeside towns - Savonlinna, Lappeenranta and their harbours and castles.
- Summer cottage life - the Finnish tradition of the lakeside cabin and sauna.
When to go
High summer for swimming, boating and the warmest water; late summer for lake cruises and calm. The lake half-freezes in winter, a different, silent landscape.
Honest expectations
Saimaa is enormous and diffuse, so there is no single place to see it - you pick a base and explore the water from there. Its pleasures are gentle and slow, boating, swimming and cottage life, rather than headline sights. A boat or a lakeside stay makes it, a quick roadside stop does not.
Nearby
Savonlinna and its Olavinlinna castle sit on the water; the Saimaa Canal links the lake to the sea near Lappeenranta.
