Free spot with restrooms (no showers). Just of the Natchez Trace parkway, which is nice for biking and scenic drives. A small trail takes a tour of the remains of a ghost town. Camping spots are spread out and have decent tree cover. Saw deer in the campgrounds on my last visit.
Free spot with drinking water. Vault toilet. A few actual spots with fire pits and tables, but lots of make shift spots around the lake. Gets really crowded during weekends but if you get there early, you can find a secluded spot.
Pros: Very nice campground. Clean bath houses with showers, beautiful lake with a small beach. Access to mountain bike trails. Verizon cell reception for those going completely out of touch.
No's: Campsites are on top of each other with very little tree cover. Also, tents cannot be set up on grass; only on their "tent pads." (jagged rocks). I asked the camp host if any sites had actual tent pads instead of rocks and was told no.
