Katy Trail and Monarch-Chesterfield Levee Loop

This cycling loop, covering approximately 41 kilometers (25.5 miles), generally takes around 2 hours and 30 minutes to complete. This duration is for cycling only and doesn't include stops for sightseeing or breaks.

The route combines two distinct surfaces. The Katy Trail section is primarily crushed limestone, which is generally flat and firm, but can be softer after rain. The Monarch-Chesterfield Levee Loop features a smooth, paved asphalt surface. Both sections are notably flat with minimal elevation changes, making for an easy ride.

Given the mix of crushed limestone and paved surfaces, a touring bicycle or a hybrid bike with tires 32mm or wider is recommended for optimal comfort and performance. Road bikes with 25mm or wider tires can also be suitable, especially on the paved levee sections.

Along the route, you'll pass by the Bayer Chesterfield Campus and enjoy a View of the Missouri River. The Katy Trail section offers diverse scenery including river views, limestone bluffs, forests, and farmlands. The Monarch-Chesterfield Levee provides elevated views of farm fields, timber, and even the Spirit of St. Louis Airport.
