Jo,
We have not camp at the State park in Utica, IL. The park dose not have full hook ups, one of my DW conditions for camping. We have driven thru the campground and I would suggest you ask the ranger at check in which site is best for you. You can always move to a better site, if no one is on it after you have made your advance reservation. I have done this at other state parks in IL. I seem to think the west side of the park was better.
We have stayed at two private parks in Utica IL one was the KOA about three miles North of the park and the other is right off of RT 80 on the North side. Nice park but you can hear the trucks go by all night, even at the very back of the campground. Both of these parks have full hook ups and pull thru sites.
I also for got to mention that there are not many 30 AMP sites here either so that may limit your choice.
We live about 1 (one) hour northeast of Utica,Il.
