Governor Nelson State Park is a 422-acre (171 ha) Wisconsin state park in Waunakee, Dane County, Wisconsin on the shore of Lake Mendota. It is named for former Wisconsin Governor Gaylord Nelson. On most days the Wisconsin State Capitol building can be seen in nearby Madison. Common activities include boating, fishing, picnicking and swimming. There is also a boat launch and a swimming area for pets. Away from the lake one can find restored prairie and savanna, effigy mounds, hiking trails and ski trails. Governor Nelson State Park is one of the few Wisconsin state parks that does not allow overnight camping.
