The Saimaa Canal connects Lake Saimaa to the Gulf of Finland at Vyborg, a journey of 43 kilometres through 8 locks. It was originally built by the Tsar in the 1850s to facilitate trade from the Finnish lake region to the sea, and its history is inseparable from Finnish-Russian relations — the canal's lower section passes through territory that was Finnish until the Winter War of 1940.
Boat trips along the canal depart from Lappeenranta harbour and are a popular summer excursion. The canal's working locks, opening for cargo ships and cruise vessels, are fascinating to watch. The canal route to Vyborg, offering a glimpse of Russian Karelia, was suspended during periods of political tension but has historically been available in summer.
