This is a paved trail that runs on top of the Levee that protects the Chesterfield Valley from the flood waters of the Missouri River. It is well-used and you can expect to encounter other cyclists, runners, in line skaters, and folks just out for a walk. The Monarch Levee Trail is linked to the World Famous KATY Trail via a separated bike lane on the Interstate 64 bridge across the Missouri River. There are plenty of parking areas along the trail length. I chose the trail head parking off of the Centaur Road. Expect to see wildlife such as foxes, turkey, deer, raccoons, and other critters mainly on the river side of the trail. On the Valley side is an airport, outlet mall, shopping centers, and entertainment venues. If you are looking for a peaceful serene ride this is NOT it. On a historical note, this levee was built after the devastating floods of 1993. This levee is nearly twice as high as the original levee. If you can imagine when you are looking out over the valley, the airport and all the buildings there, that in 1993 there was nearly 20 feet of water covering all of it! Rescue personnel used the interstate, which crosses the valley, as a boat ramp. All in all this is a well maintained wide trail that you will enjoy riding.

However, road bikes with tires 25mm or wider can generally manage the well-packed surface.

For instance, the St. Charles trailhead for the Katy Trail is a popular starting point with parking. Parks like Klondike Park and Frontier Park also provide convenient access and parking for cyclists.
