April 18 visit help

Hi all :grinning: I apologize if this is a repeat question. I’m brand new to this site. We are visiting Hocking Hills with our 3- and 5-year-olds from April 18-20. I have looked through the app, and it looks like most things in the area are either still closed for the season or too old for my kids. We will definitely do a good deal of hiking, but I’m looking for any other suggestions for activities. Thank you much!
