In Dover, TN, at the intersection of State Rt 49 east and US Rt 79 south, take Rt 79 west 10.7 miles to Piney campground sign. Turn right at sign onto Forest Rt 230 and go 4.5 miles to Boswell Landing sign. Turn left at sign onto Forest Rt 232 and go 0.2 miles to a boat ramp sign. Turn right at sign onto Forest Rt 233 (paved and gravel) and go 1 mile to campground.
Easy, convenient check in (fill out an envelope, put $10 cash inside, and put in drop box). Please understand, this is a primitive campground. No electricity. No water hook ups. No bath house. Toilet (outhouse) only. There are lots of good sites with great views and most of them have a picnic table and fire ring. There is a small floating dock beside a boat ramp. There is a dumpster for trash. Several bike/hiking trails are close by too.
Nice, quiet spot to camp. Boat launch is easy access and parking. We found a sand bar in the cove. Small trail just next to the boat launch ramp.
As far as back country primitive camping goes, this place is great. Most sites are right on the edge of the lake. There is a boat ramp and dock as well as a vault toilet. Camp ground was fairly clean and mostly litter free, so it shows they come through frequently to keep on top of it.
If noise in the early mornings bother you I suggest not picking a site near the boat ramp as the ramp is not just for people camping there, and people show up at the crack of dawn to launch their boats and aren't exactly respectful of campers who are sleeping.
Also, keep in mind that sites here are first come first served, so have alternative plans during busy camping season in case all sites are filled once you arrive.
