The island of Vilsandi, Kihelkonna Commune, Estonia is located in the Baltic Sea. It covers an area of some 9 square km and is the westernmost populated island in Estonia. The surrounding waters are shallow and rocky and many ships travelling the Baltic have perished nearby. The island of Vilsandi can be reached by boat, by truck having suitable clearance or on foot by wading from Saaremaa. Much of the island is now part of Vilsandi National Park, which 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.
