Lake Saimaa
Lake Saimaa
Lake Saimaa, a vast maze of islands and forests in southeastern Finland, is explored by kayak, cruise or on foot from Lappeenranta. Home to the rare ringed seal, it offers pristine lake landscapes throughout the year.
Lake Saimaa stretches across southeastern Finland, forming Europe's fourth-largest lake by surface area. From Lappeenranta, the gateway city to Saimaa, you gain access to a labyrinth of islands, straits and pine forests that define the Finnish lake landscape. It is also home to the ringed seal of Saimaa, one of the world's rarest freshwater seal species.

What you'll see
Saimaa is a network of over 130,000 islands and islets linked by shallow channels. Scots pine and spruce vegetation stretch down to the water's edge. Granite rocks polished by glaciers emerge everywhere. In summer, Finnish cottages (mökki) dot the shorelines; their wooden saunas overhang the lake directly.
History and context
Saimaa owes its current shape to glaciers that carved the region roughly 10,000 years ago. For centuries, it served as a trade route for timber floating toward the Baltic. The Saimaa Canal, opened in 1856 and rebuilt after World War II, still connects the lake to the Gulf of Finland via Vyborg (Russia) today. This canal remains a major historical infrastructure of the region.
Highlights of your visit
The Saimaa ringed seal
Around 400 individuals remain in the lake, classified as critically endangered. Observation cruises depart from Lappeenranta in summer. The animal occasionally lets itself be spotted on sun-warmed rocks, especially early morning or evening.
The Saimaa Canal
About sixty kilometres long, this lock canal connects the lake to the Baltic Sea. A cruise on the canal from Lappeenranta lets you observe the locks in operation and the border forest landscapes.
Archipelago navigation
Renting kayaks, canoes or small motorboats allows you to explore islands without road access. Some islands shelter public refuges under Finland's right of passage (jokamiehenoikeus).
Ice fishing in winter
From January to March, the lake freezes sufficiently for ice fishing. Local guides organize outings with equipment provided from Lappeenranta.
Photography tips
The raking light of the white nights in June and July offers golden tones on the water until midnight. Granite rocks in the foreground with forest in the background form the classic Saimaa frame. To photograph seals, a telephoto lens is essential: approaching closer than 100 metres is discouraged to avoid disturbing the animals.
Location and access
Lake Saimaa borders Lappeenranta directly to the north and east. The city's pleasure marina is the departure point for cruises and boat rentals. Lappeenranta railway station is a few kilometres from the marina. Lappeenranta airport offers connections to Helsinki and a few European destinations.
