Stretching 240 miles across Missouri, the Katy Trail is the longest developed rail-trail in the U.S., following the former Missouri-Kansas-Texas Railroad corridor. This crushed limestone path offers a flat, scenic route for cyclists, hikers, and equestrians, closely tracing the Missouri River and passing through charming towns like Rocheport, Boonville, and Augusta. Along the way, you'll encounter towering bluffs, restored train depots, and historic sites linked to the Lewis and Clark Expedition.
