Park Information
Onondaga Cave State Park is closed until further notice due to hazardous road conditions resulting from the recent winter storm. For the most up-to-date information, please visit our Park and Site Status Map.
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 peaceful and scenic setting.
