Our go to spot!
We live in Madison, AL and love driving out to Cathedral Caverns to camp on the weekends. It has a smaller but decent primitive campground. A quick drive down the gravel road and you're at the RV park with bathrooms. There are also two backcountry sites if you want to hike a mile or so. It's never too crowded and always clean! WARNING: Very spotty cellphone service, which is actually nice if you want to enjoy the outdoors!
