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!

Had to include this very unusual find. I am assuming that this was a family cemetery and when the new levee, on top of which this bike trail runs, was built it must been over the old cemetery. So they relocated the cemetery to the top of the levee. These are very old, dating back to the 1890's. Be respectful and do not desecrate this place.

One of 3 major highway bridges over the Missouri between Weldon and St Charles, MO. The KATY trail through here is as smooth as concrete and the scenery is beautiful!
