18 Reviews of Onondaga Cave State Park
Absolutely loved it!!

Saw both caves in 1 day and they were more than worth it! Great hiking trails with stunning views. Peaceful and quiet camp. Showers were great. Will definitely be back!!

Close to interesting cave

The campground has limited parking and some of the terrain was hilly but still a nice getaway with a cave nearby to visit!

Great State Park

Great Campground, clean campsites with good pad for trailers, close to cave tour, and really nice trails!!

Beautiful with lots to see

Loved the cavern tours, great trails but did have a little problem with ticksthis year even with spry

Great place to explore and camp

My favored cave in Missouri by far. I highly suggest you go for the day or stay the weekend and enjoy the cave tours and surrounding area.


Small park with great trails and views and of course the cave. Good level sites with shade. Great place for kids.

Great Campgrounds

My one regret is that we didn't get to take a cave tour. Definitely going back!

The facilities and campsite were all really clean. Our neighbors left all of their food items on their picnic table, and had a justifiable raccoon encounter overnight. I would think any responsible camper would have no issues with critters here otherwise!

The park is very easy to get to. Like other MO State Park campsites they all have picnic tables, fire pit, and area for a tent. The basic loop, sites 1-13, are not very private, but would be ideal for a group of people sharing space and adjacent sites! We stayed in site 16, which backed to the woods but was at the beginning of the long road toward the rest of the campground, so there was comparatively high traffic to other campgrounds with separated loops.

RV camping and Caves

A good place for RV camping, not so much for tent camping. This is a campground with RVs in mind- large parking pads, tons of sites with hookups, and small green space for tents. No privacy as the trees are along the back of the camping row. Which means there really isn't anywhere for a person to hang a hammock. But, the campground was sparkling clean. The bathrooms were new looking, and shower passes could be purchased for $5 from the camp host if you weren't camping but needed a shower. I guess they have had some boaters from the Meramec River come up and use the facilities. If you are camping on the weekend you do have to pay for two nights (F/S or S/S).

The real draw of this park is the caves. You can tour the main cave from the Visitors Center. $15 will get you a guided 90 minute tour of Onondaga Cave. Afterwards you really should take the hike on Herron Trail to see the original entrance to the cave, which is mostly underwater unless its a really dry season. There is also a second entrance that is gated, so if you want to go in, you have to pay up at the Visitors Center. There is apparently another tour offered for Cathedral Cave, but it wasn't open while I was there. The tour of Onondaga Cave was worth every penny and makes camping here worth it.

Off season

Onondaga Cave State Park has a very well maintained, long campground. It meanders through a hilly area and affords campers with several locations to have some privacy from other nature seekers and the inevitable bring the kitchen sink campers too. The lower campsite is prone to flooding but has direct river access.

Unfortunately we arrived the week after the Onondaga Cave had closed for the season to let the resident bats get some well deserved hibernation privacy and quiet. We were still able to enjoy the many trails offered and fall colors just ramping up. The campground is off I44 outside St Louis, Mo and surrounded by several other parks including part of the Mark Twain National Forest.

Showerhouse facilities were small but well maintained and decorated by the local high school and laundry facilities were on site. Keep your pup leashed even on site and watch for local wildlife which may show up at your doorstep.

So much to do, you'll go batty

Cave systems and tours are seasonal, so be sure to call ahead for tour availability if you are wanting to tour the caves. DNR is working hard to deter white nose disease in the bat population, so cave tours cease from mid-Oct to April.

Campground is well kept. Laundry, shower house and restrooms are very well kept. High school art class painted murals in the restrooms, which are rather neat. Trails are everywhere and well marked.

No cell signal & limited cell signal!! Best signal was actually on the trails or in the church parking lot up on Highway H & Nixon School road.
