The natural beauty that characterizes Missouri is more than skin deep. Missouri, the Cave State, has more than 5,500 caves, and some of the state's most scenic natural wonders lie beneath the surface -- in caves. One Missouri cave stands out above the rest -- Onondaga Cave in Onondaga Cave State Park. Deep underground there is a world that nature has created using water to form deposits of tall stalagmites, dripping stalactites, active flowstones and many other colorful deposits. Onondaga Cave, a National Natural Landmark, and Cathedral Cave showcase these natural wonders, which can be viewed during cave tours. There is also plenty of natural beauty to enjoy above ground at the park. Vilander Bluff Natural Area provides visitors with a panoramic view of the Meramec River. Come and take a hike through the Meramec River valley, canoe or fish in the Meramec River or enjoy a picnic lunch. Learn about the park's natural resources above and below the earth's surface through exhibits inside the visitor center. The park's campground offers both basic and electric/water campsites, many of which are reservable.
I have camped here twice now. Hiked some of the trails, toured the for fee cave, canoed the adjacent Meramec River, and hiked the adjacent Huzza conservation area. A wide variety of things to do. Great, well maintained campgrounds, from primitive tent to nice RV sites. A nice destination for camping and plenty to do when your are there.
Meramec river is a meandering spring fed class I float stream. Very scenic in the upper portions. Many sand bars for primitive camping. Great fishing. Great for kids. Many outfitters and can be canoed a couple miles or a hundred miles. highly recommend. Many outdoor recreational opportunities in the area.
