The Katy trail is a railroad track that has been converted to a bike path. It stretches all across MO. We specifically did the stretch from Rocheport to Jefferson City on the 4th of July. Because it was a former railroad there are no steep grades and it is an easy bike ride with some beautiful scenery. We specifically like the rocheport area because of the train tunnel there. It is a beautiful place to go ride a bike. We brought our own bikes but you can rent them if you like. I have included some other information about the katy trail if you are interested.
The Katy Trail is a 225 mile (365 km) bike path stretching across most of the state of Missouri. Over half of it follows Lewis and Clark's path up the Missouri River, where you can ride beneath towering river bluffs while eagles circle overhead. After leaving the river, the trail meanders through peaceful farmland and small-town Americana.
America's longest "rails-to-trail" project, formerly the MKT rail line, is flat and scenic. It's ideal for hiking, running, or cycling on just about any kind of bike. Horseback riding is also allowed on a 25 mile section of the trail. Many cross-country cyclists include the Katy Trail in their tours. It is part of Adventure Cycling's Lewis & Clark route, as well as the American Discovery Trail.
