In all, this trail covers approximately seven miles in its entirety, but with multiple road crossings, and trail crossovers, it can be adapted to a shorter route if you like. It should be noted that the trail is often poorly marked, in many places in rough condition, has lots of blow downs across the trail, and in the lower Natural Area, has multiple stream crossings.
As you can see on the GPS image from my hike, I did leave out one portion of the hike. The main reason for this was that as I proceeded through one of the burn areas, I lost the trail, and it was not marked, so I moved out to the road and proceeded back to my vehicle (a short distance).
This area is in the western section of Warren County in Missouri. It's about one hour from my house...maybe 1:45 from St. Louis
