Il start this by saying: we prefer tent camping/primitive/atleast semi isolated spots. If you’re looking for RV camping, this is probably a decent spot so read no further!
We drove in to the Middle Fork Forest Preserve looking for a place to camp same day on our way down to Giant City. We weren’t able to make a reservation less than 5 days in advance online so we tried to call. No one in the office except Th-Sunday and it was Wednesday so we couldn’t get in touch. All good. It happens and it did say that clearly on their website and on voicemail. We needed a place for the night so decided to risk driving over from I57 S. Rolled in around 5 and all the campsites were marked reserved but there were about 3 people set up to camp there. We didn’t end up camping the night 1. Because we didn’t want to be jerks about the reservations although it seemed like no one else would be arriving until at the earliest the next day and 2. All of the campsites were pretty tight together and surfaced with gravel. That’s a personal preference thing. We always look for primitive/walk-in/hike in sites to set up tents/hammocks. This spot was mostly set up for RVs.
The hiking looked pretty lovely and the grounds/facilities looked well kept! Just maybe not our preference.
