See cave formations and learn how they are formed. Trudge through the “Valley of the Lost Soles”! Visit Stewart Spring, Indiana’s 13th largest spring, from underground. Wade the stream to the waterfall. Along the way you may encounter cave fish and possibly even blind crayfish.
On the way out, challenge yourself with optional crawls. Then exit from the “Pig Pen” named for the slimy wet clay you’ll be covered in! Great, not so clean, fun!
Ages 10 and up. Event is held every other Saturday from June through August.
