We stayed at High Falls RV Park for just a few days in August 2018 and returned in May of 2019.   Both times, we were in the area for a business-related meeting in Covington, GA, and chose this park for its convenient location between Atlanta and Macon and not too far off I-75.  This park is independently owned and pretty small with just 38 sites.  We enjoyed this campground very much.  The very shady grounds were a nice relief from the August Georgia heat, and the small size and adequate distance from the interstate made for plenty of peace and quiet.
