The trail is marked every mile with a sign post that corresponds to the historic railroad mileage system. Mileage will not be exact because the trail deviates slightly from the original railroad corridor in a few sections. Between St. Charles and Black Walnut, for example, the Missouri River floods of 1993 and 1995 washed away a portion of the original railroad, requiring the trail to be built outside of the original corridor and on top of the L-15 Levee. Other similar examples exist in several places along the trail. To determine the approximate distance traveled, subtract the milepost number at the trailhead from the milepost number on the trail or vice versa. Milepost 26.9 is located on the east end of the trail at Machens in St. Charles County and milepost 264.4 is located on the west end in Clinton in Henry County.

- For emergencies, call 911 (or *55 from a cell phone)

BE AWARE OF YOUR SURROUNDINGS
The trail passes through some remote areas and adjoins private property. Adjoining property may be used for commercial or business opportunities, quarrying, farming operations or hunting.
Please respect private property by remaining on the trail. Many sections of the trail are alongside bluffs. Do not climb on bluffs and be aware of falling rocks. Additionally, because the Katy Trail parallels the Missouri River for much of its length, area flooding can close certain sections of the trail. Rough areas, minor debris and downed trees can also occur at any time on any section of the trail due to weather variations. Flooding and other advisories are posted at katytrailstatepark.com.
PLAN AHEAD FOR YOUR TRIP
Do not exceed your physical capabilities by planning too long of a trip. For long trips, carry food and water, especially in the summer. Water is not available at all trailheads. Trailheads with modern restrooms and drinking water are winterized from Nov. 1 to April 1. The restrooms are closed and water turned off at these trailheads.
KEEP PETS ON A LEASH
State park regulations require leashed pets. Be considerate of other trail users and adjoining landowners.
As a courtesy, please notify other users when you plan to pass them from behind. Additionally, when traveling in a group, move to the right when meeting oncoming users.
UNDERSTAND EQUINE BEHAVIOR
Horses have the instinct to run when they feel threatened. For your safety, follow these guidelines when approaching a horse and rider. Bicyclists and hikers should stop to allow the horse to pass when approaching from the opposite direction. When approaching from the rear, announce yourself. Always speak in a friendly tone to avoid spooking the horse. Follow any instructions given by the horse rider. Yield signs on the trail remind bicyclists and pedestrians to yield to horseback riders.
