As Gary suggests, it should be easy to see in the Trail Map link above, especially when on satellite view. The access trail is about mile 51.2, it appears. It is an easily accessible paved path, although it does climb up (gentle incline) from the Katy Trail to the interstate. It is about one mile from the Katy to the edge of civilization - the big outlet mall on the west side of Chesterfield. It would be a bit further to get to restaurants or hotels, but you can estimate those distances on the map link above or any map website.
