Review & FAQ:
Onondaga Cave State Park is located on the Meramec River about five miles from the village of Leasburg. The park was established in 1982 and has been declared a National Natural Landmark. The walking tours of the Onondaga Cave take visitors through well-lit one-mile long paved walkways, and guides provide detailed information about geological features such as the Twins, the King's Canopy, dripping stalactites, massive stalagmites, active flowstones, and other unique speleothems. There is even a river flowing slowly through the cave. Outside the cave are the park’s other attractions such as Vilander Bluff Natural Area with a wonderful view of the Meramec River and access to the Meramec River where visitors can fish or canoe.
