Atlantis Playground in Garden Grove, CA is an enclosed spacious playground that features marine life themes throughout the park.  The park is maintained well and clean. Kids will have fun sliding down the serpent slide, swinging on the swings or racing to the other sea-themed structures. An especially nice feature about this park is that no adult is allowed in without a child and no child is allowed in without an adult...which add to the overall safety of the environment. There are plenty of spaces to picnic and plenty of picnic tables to host your own party (w/reservations), if you chose.
