You have to find this one. Once you do, it is interesting. We did not tour the cave, but it is popular with both campers and day-trippers. It is a long,steep walk from the check in stop to the office. If you are mobility impaired, flag down one of the staff carts. They will be happy to give you a ride. The spaces are large but ill defined, We had to ask our neighbors to move their coolers, chairs, etc before we could back in. We would stay here again, but only in the middle of the week. We camped here in a Fifth Wheel.
If you don't mind no cell phone, local TV or satellite reception this would be a good place to take young children. Perhaps the sites on the road that enters the campground might get some type or reception but every one who goes in or out of the campground will drive by your campsite. The train goes right through the campground but I did not hear it during the night. For those with out children this is not a bad place for an overnight stay. We were in the are for two days to do some business. The sites were adequate size but because of side by side hook ups the picnic table/fire pits face each other. We camped here in a Motorhome.
Nightly rate based on a this was one of the worst places we've been to. The interior road was supposed to be gravel, it was a limestone dust road. The speed limit was supposed to be "5" and we all know that song and dance, especially when the help and hosts haul butt in the golf carts kicking up a big cloud. But the best was the railroad tracks through the campground. When I asked how often they come through, I got "around 4-5 times a day" and yes that includes during the night! At the entrance of the campground the tracks cross the road so of course they have to blow and blow and blow the horn and if that doesn't wake you then the weight of the train shaking the ground and everything on it will. Thankfully I didn't have to do laundry, and after opening the laundry room door there was no way I could have. The stench was so bad and the room was filthy. The Spook Cave tour will cost you another $10 per person for a 30 minute tour. It's not worth that much money. My advice skip the cave and keep on rolling. We camped here in a Motorhome.
Stayed here 10 days and loved it!! Spaces were huge with lots of trees, grass and a creek running right behind the rig. The train was a minor inconvenience now and again. Very close to Prairie Du Chein, Macgregor, Effigy Mounds and many historic sites. Quiet, even though the campground was busy with campers and folks coming to see Spook Cave. Would stay here again!!
