From Memorial Day weekend through Labor Day weekend, the water complex opens at four of our Regional Parks. Swim lagoons, water slides, sandy beaches, and shady lawns are the perfect combination for fun and relaxation. All our swim facilities have trained lifeguards on duty and first aid stations.
Special rates are available for larger organized groups (like scout troops or schools) and it's even possible to reserve time for a private party. Call your park to ask for details. (School groups only at Lake Gregory Regional Park, all others excluded.)
