Mission Bay Park covers 4,235 acres in San Diego, a little over half of it water, and it is the largest man-made aquatic park in the United States. The bay opens to the Pacific through a narrow entrance channel between Mission Beach and Ocean Beach, and city parks close it on the other 3 sides. Crown Point Shores, Vacation Isle, Fiesta Island, and De Anza Cove are the major named areas inside the bay, and SeaWorld sits on the south shore. Open-ocean swell does not reach the interior in any season.
