Oak, Illinois Map

I go here just about every other week and of you go in near Frank's tract, the path is marked well and there are wooden signs to guide you. awesome hike. after secret canyon I suggest following trail 457 to trail 481 and you can see saltpeter cave on your way back

Markers for trail were not very good. We got lost & hiked for 5 hours because the markers kept sending us in the wrong place. If you go to this trail, go to the water & then turn around, secret canyon is when the trails start getting sketchy with markers.

gorgeous trail and waterfall; however, I'm not sure how it's a loop. Recommend going to the water and Turning around!
