The Lake District in Finland is the largest of the four regions into which the country is divided. The landscape of the lake plateau is covered with drumlins and eskers, which are glacial deposits of huge glaciers that receded thousands of years ago.
Lake District occupies most of East and Central Finland. The Salpausselka Ridges to the south are terminal moraines that trap numerous lakes divided by countryside. Turning into the Coastal Finland towards the west, the Lake District has Upland Finland to its north. Due to the lake landscape that continues towards the East and continues into Russia, there is no natural border between these countries.
