The M.K.T. Trail is a recreational rail trail in Columbia, Missouri, that runs nine miles in the right-of-way of the former Missouri-Kansas-Texas Railroad. It is a spur of the longest rail-trail in the United States, the Katy Trail. It is open for use by hikers, joggers, and cyclists year-round, from sunrise to sunset. The trail is made up of "limestone pug" creating a hard flat surface. The trail follows Flat Branch Creek and Hinkson Creek for much of their distance and is part of a larger system of ped-ways in the Columbia, Missouri Metropolitan Area.
