Onondaga Cave State Park

Park Information

Descend into the depths of Onondaga Cave State Park and drop into a world of wonder: towering stalagmites, dripping stalactites, and active flowstones help make the cave a National Natural Landmark and illustrate why Missouri is often called “The Cave State.” Visitors can take guided tours into the underground wonderland. But if you prefer the surface, the park’s Vilander Bluff Natural Area provides a panoramic view of the Meramec River. Easy access to the Meramec River allows visitors to canoe or fish in a bucolic setting.

Park Hours

The park is open year-round for camping and day use.

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.
