Is it a beach or is it a park?  

It's a place next to water and depending on where the beach park is located it's hopefully warm. There's sand next to a body of water, making it a beach, or you can have a picnic, hopefully on some grass or under a pavilion, meaning you're in a park. 

Why not have both and, if you're sitting in front of a computer and not at an actual beach park, here you can at least enjoy a picture and description of beach parks that exist as both beaches and parks at the same time. 

Pelican Beach Park is a beach side park located only steps from the Atlantic Ocean! Encompassing 74 acres, this public park maintained by the city of Satellite Beach boasts four pavilions, public fresh water showers, restrooms, playground, volleyball courts and dune crossovers. To use the public pavilion, please call parks and recreation to reserve in advance.

Goleta Beach Park

Known for its long fishing pier and sunbathing beaches, these 29 acres are often a destination for bicyclists on the area's paved trail system. Between the lively restaurant and BBQ picnic areas are volleyball, horseshoes and children's playgrounds.

Orient Beach State Park, located on the eastern tip of the north fork of Long Island, is a natural wonderland of waterfront with 45,000 feet of frontage on Gardiner's Bay and a rare maritime forest with red cedar, black-jack oak trees and prickly-pear cactus. Its natural beauty earned designation as a National Natural Landmark in 1980. Other natural attractions in the park include the salt water marsh and marine wildlife. Great Blue Herons, Egrets, Black Crowned Night Herons, and Osprey are common sights in the park, leading to its recognition as an Audubon Important Bird Area.
