With weather warming up, families are eager to begin spending weekends by the lake, and with six Lake Lanier campgrounds opening today, people can enjoy the season every day. Lake Lanier campgrounds, operated by the Army Corps of Engineers, offer a variety of services from campsites to beaches, boat ramps and picnic areas. One of the locations, Bolding Mill Campground, is open year-round, and the others unlock their gates today.
