This is a state park in the north Georgia mountains and is great for cooling off from the Atlanta metro heat of the summer.   The campground is well maintained and the bathhouses are very clean (they have individual ones).  The park has some great hiking trails from easy (lake trail), moderate (Bear Hair Gap), and  hard (Blood Mountain), as well as a lake for paddling, and spacious campsites in the woods. Helton Creek Falls is just up the street, and Brasstown Bald(highest point in Georgia(4,784 ft.) is about 20 minutes away. You can access trailheads for Blood Mountain on the AT from both the park (long at 8+ miles) or drive 5 minutes down the road for a shorter hike at(4.2 miles). Lots of other activities with 15-45 minutes (quaint towns, vineyards, tubing etc).
