There's a fence up front but if you go around the back side you can walk right in.
People explore all the time
I've wandered these caves for 25 years and Honestly there has been several feet of the cave roof drop down the floor in the last couple of years. It is very unsafe to explore these days. Please don't take children into the caves and risk the noise causing the ceiling to collapse even further.
My husband and our kids enjoy the trails there is a big enterance at the end of the trail with no fence but its fenced off for a reason the caves are unstable i wouldnt recommend going inside really but so worth the site seeing.
