Known locally as “Devil’s Boot Cave,” this natural overhang carved in sandstone resembles the shape of a boot and stretches roughly 25 feet deep and wide, near Marthasville. Once used as a pioneer shelter and noted by local schools for nature trips, the site offers a little geological curiosity beside the trail—a hands-on reminder of Missouri’s limestone landscape and early frontier life. Great for a quick stop and photo op!
