The Katy Trail is the longest rails-to-trails project in the US and was converted from the prior MKT (Missouri - Kansas - Texas) Railroad. Notably, it passes through rolling farmland, forests, and tallgrass prairies.
The Katy Trail begins southeast of Kansas City in Clinton and runs nearly 240 miles to Machens, Missouri which is just east of St. Charles. No two sections of the trail are the same and the natural beauty surrounding the trail changes with the seasons. Food, lodging, and camping are all convenient to access from the trail for multi-day trips. Primarily, this trail is used by cyclists, but it is also used by thru-hikers.
In most places, trailheads and rest stops conveniently sit off to the side of the trail with water and facilities. Occasionally, the trail follows along portions of the highway, however, the bulk follows the Missouri River, farmland, and forest. The trail is covered with a crushed stone, giving the feel of a hard dirt road. Being a prior railway, the trail is mostly flat and well marked along the way.
