Ha Ha Tonka State Park

Park Information

WHERE NATURE AND HISTORY COME TOGETHER

Ha Ha Tonka State Park with its intriguing history and outstanding geologic features, Ha Ha Tonka State Park is one state park that should not be missed. The park is a geologic wonderland with sinkholes, caves, a huge natural bridge, sheer bluffs and Missouri’s 12th largest spring. The ruins of a turn-of-the-century stone castle overlook these wonders and offer impressive views of the Lake of the Ozarks and Ha Ha Tonka Spring.

A series of trails and boardwalks makes it easy for visitors to experience all the park has to offer from its historic castle and geologic wonders to its wooded areas and open rocky glades. Picnic sites beckon visitors for a relaxing lunch in a scenic setting unparalleled in the lake area. All these fascinating features combine to create a park that can be explored and enjoyed time after time.
