Between mile markers 93.2 and 89.0, the Katy Trail offers some of its most breathtaking views of the Missouri River. This section features sweeping vistas of the river, dramatic limestone bluffs, and serene floodplain landscapes. The Missouri River, often called the "Big Muddy" due to its high silt content, is the longest river in North America, stretching over 2,300 miles from Montana to its confluence with the Mississippi River near St. Louis.
