I took this image at the pier in Bolding Mill Campground. The water is very low right now but I think this could be a great spot when the lake fills back up as well.
Bolding Mill Park is located in Hall County, GA on the northern end of Lake Lanier. It has a lot of amenties including a beach, campground, fishing, boat ramp, restrooms, as well as hiking trails. It is somewhat off the beaten path and I would consider it a hidden gem.
