Plan a bike tour to explore the beauty of Missouri, along the 225-mile long Katy Trail State Park, built along the former Missouri-Kansas-Texas Railroad corridor and perfect for wildlife watching, scenic views and access to rural towns such as St. Charles and Clinton. Known as the Cave State, there are more than 6,200 caves... more that tunnel underneath Missouri, and the world's largest subterranean lake, Bonne Terre Mine, is also found here. Over a million acres of surface water in the state provides for great fishing. Fly fish for trout in ta spring-fed Ozark stream or catch monster catfish on Missouri's Big Rivers - the Missouri and Mississippi. More than 200 species of fish can be found here, including the ancient paddlefish, bass, and bluegill, and plenty of mussels and crayfish can also be found. With large populations of white-tailed deer and wild turkey, hunting is big sport throughout 3 million acres of state and federal lands.
