Vilsandi National Park is a national park in Saare County, Estonia. It includes part of the island of Vilsandi, a number of smaller islands, adjacent parts of western Saaremaa and the Harilaid peninsula on Saaremaa, all in Kihelkonna Parish. The park grew from a bird reserve founded in 1910. It is a highly sensitive ecosystem due to the use of the area by many migratory birds as a breeding and nesting ground. Hunting is absolutely prohibited. This park is a popular tourist destination for both Estonians and foreign visitors, particularly from Finland.
