The pull through sites were okay, but not what I would really call big rig accessible. We have a 40' m/h towing a Ford F150 p/u and found the sites short and narrow. Also, some of the electrical hookups were open on one side, all 4 prongs hot and what we would consider sloppy electrical work. We camped here in a Motorhome.
This is a very small out of the way park. We wanted to visit the caverns, so spent the night there, and we were the only ones there with small deer roaming around and bats feasting on the bugs around the nightlight! Needless to say it was VERY quiet which was nice. They have no ammenities other than water and power, and there is only 2 spots with shade. We camped here in a camper.
