Tricky to get to but a great access to the KATY Trail.

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!

This part of the Al Foster trail is more challenging than the Western part. Wider tires recommended.

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!
