Ha Ha Tonka State Park

Park Information

Imposing architecture and breathtaking scenery combine to make Ha Ha Tonka State Park one of Missouri’s most treasured spots. Located on the Lake of the Ozarks, the park features the stone ruins of a turn-of-the-20th-century castle built by a prominent Kansas City businessman high atop a bluff. More than 15 miles of trails traverse the park, leading visitors to sinkholes, natural bridges, caves and down to the lake.

Sometime between 1936 and 1938, the Missouri State Society Daughters of the American Revolution published “The Old Tavern; Book of Recipes,” which contained more than 700 recipes from DAR members and the J. Huston Tavern at Arrow Rock State Historic Site. The recipes offered a unique glimpse into our food culture during the early years of the 20th century. On page 36 is a recipe for buttermilk biscuits: “Add to ½ sifter of flour, 1 scant tsp. soda, ¼ tsp salt, 2 level tsp. baking powder. Sift into mixing bowl. Cut in with fork 2 heaping tbsp. lard, 1pt. buttermilk. Turn onto floured board, knead to soft dough, Roll 3/8 inch thick. Bake in greased pan in hot oven. 30 biscuits.” You can try the recipe itself or enjoy the fine food served today at the J. Huston Tavern, the oldest continually operating restaurant west of the Mississippi. For more information, visit http://www.mostateparks.com/park/arrow-rock-state-historic-site.
