Lake Saimaa is in the province of Eastern Finland, in what many call the Finnish lake district. The lake is not just a lake basin, but a labyrinth formed by wide waters, with the world’s longest lake coastline (14.500 km long) and 13.710 islands. This is Finland’s largest lake, and it’s the fourth largest natural freshwater lake in Europe. Wall Street Journal listed it one of the five most beautiful lakes in the world in 2014. The Lake Saimaa offers great opportunities for outdoor activities (boating, swimming, canoeing), holidays and travel.
