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!

Katy Trail State Park offers a wide selection of traffic-free cycling experiences. Our guide features 37 dedicated routes suitable for road cycling, ranging from easy to difficult, ensuring there's a path for every skill level.
The Katy Trail features a crushed limestone surface. While generally smooth and well-maintained, it's important to note that this is not paved asphalt. Road cyclists often find that bikes with slightly wider tires (e.g., 28mm or more) or gravel bikes offer the most comfortable and efficient ride on this surface.
Spring and autumn are ideal for cycling the Katy Trail. In spring, the forests burst with flowering trees like dogwoods and redbuds, while autumn brings vibrant fall colors to the hillsides. These seasons also typically offer more moderate temperatures, making for a pleasant ride. Summer can be hot and humid, and winter can bring cold temperatures and potential snow or ice.
While the Katy Trail is largely flat, some sections offer more elevation gain, particularly towards the western end. For a more challenging ride, consider routes like the Bums Cave loop from Marthasville, which is rated as difficult and includes significant elevation changes.
The Katy Trail meanders alongside the Missouri River for much of its length, offering captivating views of the river and towering limestone bluffs. You'll pass through shaded hardwood forests, wetlands, and open farmland. Don't miss the Missouri River Overlook for stunning vistas, or the dramatic bluffs between Rocheport and McBaine.
Absolutely! The trail follows the former Missouri-Kansas-Texas (MKT) Railroad corridor, so you'll encounter numerous historic elements. A notable landmark is the Rocheport Tunnel, a 240-foot brick and stone structure. Many historic railroad depots are also preserved along the trail, and a significant portion is part of the Lewis and Clark National Historic Trail.
The no-traffic road cycling routes in Katy Trail State Park are highly rated by the komoot community, with an average score of 4.4 out of 5 stars from 43 ratings. Reviewers often praise the peaceful, car-free environment, the scenic river views, and the historical points of interest along the trail.
Yes, while the Katy Trail is primarily a linear rail-trail, there are routes that incorporate sections of the trail into loops. For example, the Katy Trail and Weldon Spring Loop offers a moderate 50 km ride that combines the Katy Trail with other scenic paths to create a circular experience.
The Katy Trail State Park is well-equipped with 26 trailheads, many of which offer parking facilities. You can find parking at popular access points like the Rocheport Trailhead, or other trailheads along the route, providing convenient access to the traffic-free sections.
The Katy Trail's largely flat gradient and car-free environment make it excellent for families. Many sections are suitable for all skill levels. The stretch between St. Charles and Machens, such as the Katy Trail: St. Charles to Machens route, offers minimal elevation change and a pleasant ride for families.
Beyond parking and restrooms at many trailheads, you'll find that some sections offer bike pumps and tools. The trail connects over 20 towns, many of which provide amenities such as shops, restaurants, wineries, breweries, and overnight accommodations, making it easy to plan stops and refuel during your ride.
