This adventure is only a small part of the 239 miles of Katy Trail. It is America's longest "rails-to-trail" project, formerly the MKT rail line. The trail is flat and scenic. On this trail you will be able to view the Missouri's state champion bur oak, the Big Moniteau Bluffs and find your turn around point once you reach Lewis and Clark Cave. Trail users are not allowed in the cave but you can stand at the entrance and feel the cave air and enjoy the surroundings. The recommended tire width for the trail is 25mm or wider. There are long distances without access to water, so runners and hikers should carry water and plan ahead.
