Tourism in South Karelia went into a decline for some time after the First World War ended the flows of travellers from St. Petersburg. Interest in domestic travel, which had arisen towards the end of the 19th century, increased as conditions became more settled in the newly independent Finland. Tourism had its heyday before the 1930s depression. The area, including Lake Saimaa and the legendary beaches of Terijoki, was a popular area for holiday villas. Tourism was once more affected by the closing of the borders after the Second World War. The unspoilt nature and Lake Saimaa attracted tourists especially from Central Europe and the Nordic countries. The Germans discovered the rented holiday houses on the shores of Saimaa.
