Tips from the Community

July 28, 2025, Bums Cave

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!

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!

Greens Bottom Road is a great alternative to the Katy Trail as it is lightly trafficked and has a 45 miles per hour speed limit. It's a short stretch of pavement where you can easily access or depart from the Katy Trail.
