There isn't a cave with hieroglyphs at this state park but there is at Graham Cave National Historical Site in Montgomery County Missouri near Minneola.
No cave, but there a beautiful historic covered bridge, nice picnic areas, and a great creek to wade in. They also just added a large parking lot to handle the overflow of parking. This has become a really popular spot for family fun and relaxation.
