Keith Bridge Park<br/> Gainesville<br/> Here's one of the tiniest, most secluded lake beaches in Georgia. Lake Lanier was constructed in the early 1950s as a multi-purpose lake to provide flood control, power production and drinking water, and Keith Bridge Park is one of the resulting 46 recreation areas still maintained by the U.S. Army Corps. It has picnic tables and grills in plain view, but you'll need to drive to the end of the Keith Bridge Park parking lot and take a walkway to the beautiful secluded beach. Read, nap, picnic and dip in the lake, but be careful -- no lifeguards are on duty, so it's "swim at your own risk."
Paradise Beach at Margaritaville at Lanier Islands<br/> Buford<br/> Just 30 minutes from downtown Atlanta, this playground is part of the Margaritaville at Lanier Islands theme park and features more than a half mile of white, sandy beach with plenty of lounging spots. At Paradise Beach, you can enjoy a beverage under an umbrella, play a little beach volleyball or just take a slide down one of its many water slides. The beach, which was formerly known as LanierWorld, does not open until the first weekend in May.
