Is there a map showing the distances of all the trails

At various points along the trail it indicates what the distances are and also gives you a location code that you can call in if you have any trouble. Here is a link to the page that talks about the trails: https://www.stlouisco.com/ParksandRecreation/Trails/CliffCaveTrails

Find out more information on each trail at Cliff Cave Park by clicking the link here: http://www.stlouisco.com/ParksandRecreation/Trails/CliffCaveTrails.

Don't know. But beware, some creep approached me and my cousin.
