Ha Ha Tonka State Park

Ha Ha Tonka State Park is a public recreation area encompassing 3,751 acres (1, 518 ha) on the Niangua arm of the Lake of the Ozarks, about five miles south of Camdenton, Missouri. The state park's most notable feature is the ruins of Ha Ha Tonka, an early 20th-century stone mansion that was modeled after European castles of the 16th century. The park also features caves, sinkholes, and bluffs overlooking the lake. It is a prominent example of karst topography, which is a geological formation shaped by the dissolution of layers of soluble bedrock. A 70-acre (28 ha) portion of the park was designated as the Ha Ha Tonka Karst Natural Area in 1981.
