Let me preface everything by saying, it rained for most of our trip, so we really did not get to do a lot of the hikes we wanted to.

We had high hopes after reading other reviews.  I've been to Hickory Run State Park a number of times, about 20 years ago, never to camp, just for day trips, as my family had a home 

Once we got to our site, it was super dirty.  There was trash in the fire pit, beer bottle caps in the dirt, and other random pieces of trash all around the site that our Catahoula and 2 year old promptly brought to us.  I guess we taught them well to "leave your site better than you found it."  The water pressure was absolutely terrible, it took us all of Thursday and another 2 hours on Friday morning to fill our 40 gallon tank.  On the positive side, on Friday we had the entire 300 loop to ourselves, but by Friday night, every spot was filled.

The park itself is sprawling, and you really do need to drive to the different trail heads.  Be aware, the roads are all dirt and gravel, and they're not well maintained.  You will be dodging potholes on the roads to the trailheads.  We made it out in the rain to go see Hickory Run Lake and the Boulder Field.  Our daughter was thrilled to watch the water pouring over the dam.  With all the rain we got, it really was a spectacular sight.  Her favorite parts of the trip were going to visit the "big rocks" and see the "waterfall."
