We stayed for a week in the primitive loop and loved it! Besides one couple who was only there for one night, my family had the loop all to ourselves. There is a potable water spigot and trash cans, and the sites are well maintained. The ranger delivered firewood to us after hours for $5 a bundle. The bathhouse is within walking distance and was very clean. The check in and out staff was very friendly and helpful. There is a gate with a code for access after hours, which helped us feel safe. We have been down in the caverns before, so we didn’t go this time. The cave tour is a bit expensive and there are a LOT of stairs inside. The pool was closed because of the time of year we visited, but it looks very nice. We did not go on the trails, but my children foraged for sticks to use in our campfire. Unfortunately, there was aluminum foil and plastic in our fire ring when we got there, but I know the sites had been sold out the previous weeks. Though you can see the other primitive sites, there is more than enough space between sites. The RV sites are far enough away that it is very quiet at night (though you can hear interstate and county road traffic). It rained one entire day and night while we were there, and the road was questionable. I was worried about getting my SUV stuck. We would definitely visit again…mainly due to how quiet it has been each time we’ve stayed.
