This is a wonderful place in Rockford, IL!
The admission fee is very reasonable. You can bring young children for the splash park and creek. Our party had 2 4 year olds that played for more than an hour, took a break for lunch and rest room breaks and then went back to play some more.
The only reason I didn’t choose 5 stars is because there is so much more park to see, I want to reserve the 5th star for my next visit.
