Katy Trail State Park

The Katy Trail State Park is the nation's longest rail-trail project—nearly 238 miles of scenic trail built especially for walkers and cyclists and stretching from Clinton east to Machens, in St. Charles County. Equestrians are allowed to use the western section from the state fairgrounds in Sedalia to Calhoun only.

The trail occupies a segment of rail corridor that once carried trains of the Missouri-Kansas-Texas Railroad (a.k.a., the Katy). In 1986 the railroad ceased operations along this route, literally paving the way to creating the extraordinary recreational opportunity it is today.

The Katy Trail passes through some of Missouri's most scenic areas. In particular, much of the trail follows the mighty Missouri River, which feature amazing bluffs. In fact, the segment that passes between St. Charles and Boonville is an official portion of the Lewis and Clark National Historic Trail. The trail includes other landscapes as well, such as forests, wetlands, valleys, remnant prairies and rolling farm fields. Despite the changes in landscape, the Katy Trail is relatively flat.

The Katy Trail is part of the American Discovery Trail and is designated a Millennium Legacy Trail. The trail is open only during daylight hours only. Many of the towns along the way offer services to trail users, and you'll find many access points.
