Onondaga Cave State Park

Park Information

Missouri State Parks has implemented a number of measures designed to maintain required social distancing and protect visitors, volunteers and staff. We ask our visitors to view our Park Hours to confirm operating hours. A full list of temporary closures can be found here. The latest information from Missouri State Parks on COVID-19 can be found here.

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.
