Overview
Onondaga Cave State Park in Leasburg, Missouri, offers a unique camping experience centered around one of the country's most spectacular subterranean wonders. Designated as a National Natural Landmark, this park invites RVers to explore deep underground formations before returning to a campsite shaded by a lush forest canopy. It is a destination where geological history meets peaceful outdoor recreation, providing a quiet alternative to busier commercial parks.
Location & Surroundings
Tucked away in the scenic Ozark hills, the park is situated directly along the banks of the Meramec River. The surrounding landscape is defined by dense woodlands and dramatic limestone bluffs that characterize this region of Missouri. Located just a short drive from Interstate 44, it provides a tranquil escape that feels remote while remaining highly accessible for travelers navigating through the heart of the state.

The sites are generally paved and situated within a wooded setting that offers plenty of natural shade and privacy.
Nearby Attractions & Things to Do
The primary draw is the guided tour of Onondaga Cave, where visitors can marvel at intricate flowstones, stalagmites, and active cave formations. Above ground, the Meramec River is a favorite spot for canoeing, kayaking, and fishing for bass or catfish. Hikers can explore the Blue Heron Trail or the Deer Run Trail to observe local wildlife and seasonal wildflowers. For a scenic viewpoint, a short drive to the nearby Vilander Bluff Natural Area offers one of the most stunning vistas overlooking the river valley.
Who This Park Is Best For

Had a blast here with the family! Great tour guide, very friendly. Beautiful cave!!! Most of the tour route has rails, but it is steep in places so mind your step. Definitely give it a go if you can.

We enjoyed camping by the river. We did the basic site. I will say we stayed in 9 and if you go off the map it's semi secluded from the others, except for 8 which also has two different campers there over our three day stay, plus 7 almost 10. So I'm saying it might be better to pick some of the other ones because nobody was at any of them the whole time. Cell service was slow. Good on the hill if you went for a hike. Staff was very friendly and the bathrooms were well maintained with plenty of hot water.

My first cave experience, and I have become a big fun of caves. I felt I was in the space or some place not like earth. This is the earth and I still don’t know so many things about the earth. We must protect this beautiful place! You have to go and see it in person. Everything there was mind blowing. I was so happy that I saw it. Just go and experience cave!!

Great little campground and amazing cave. Camp sites are huge, paved and flat. Be aware there is no cell service in this area. Park host was very helpful. Our kids loved the cave and the tour guide was amazing. We really enjoy this stop.

The cave was absolutely gorgeous. Some of the ramps inside are definitely steep, so be ready to get winded! Our tour guide (I think her name was Tasha? Definitely started with a T) was incredible. She was funny and sweet and knew the answers to all of our questions. It was a fantastic experience. We will definitely come back again if we are in the area
