We camped here for 2 full weeks.  The campground at Cedars of Lebanon State Park deserves 5 stars for their proximity to Nashville, the large paved pads for campers, the peaceful woods, and their overall cleanliness.

However, we were here when there was construction going on.  It was LOUD from 8am to 4, 5, and even 6pm somedays with working trucks and digging up the Tennessee Rock.  

The weekends were peaceful without the construction, and the trails are all easy and flat.  The showers worked well and were the typical campground showers.  

The wifi that is listed on the website is basically nonexistent, so don't count on that for anything important.  But Verizon had good service, while AT&T was fair.  

Only Campground 3 was open during our stay and you can see the work they are doing here is going to make a huge difference to be big rig friendly.  Enjoy!
