5 Best Sights in New York City, New York

Stretching almost the entire length of the peninsula, this beach is separated into sections according to and labeled with the nearest cross street. In order to prevent erosion that worsened after Hurricane Sandy, certain sections of the beach are closed on various days, so check the website for details. The adjoining concrete boardwalk becomes a see-and-be-seen bazaar in the height of summer. Bikers, strollers, joggers, and rollerbladers all share space with day-trippers trying to spot their friends on the sand. There are also plenty of eateries and some swimsuit and surf shops for browsing. Amenities: food and drink; toilets; lifeguards (in season). Best for: swimming; walking; surfing; partiers.

Just steps from the subway, this stretch of golden sand is the showpiece of Brooklyn's oceanside playground. Families set up beach blankets, umbrellas, and coolers, and pickup games of beach volleyball and football add to the excitement. Calm surf, a lively boardwalk, and a handful of restaurants for shade and refreshments complete the package. That spit of land in the distance is the Rockaway Peninsula, in Queens. Amenities: toilets. Best for: people-watching; sunsets.

This 2½-mile beach, flanked by the Riegelmann Boardwalk and the amusement park rides beyond, has become an essential part of New York legend. Although open (and visited) year-round, the beach really heats up in summer, when it can feel like the entire population of New York is out sunning and swimming. In winter, you'll see Russian, Eastern European, and Central Asian inhabitants of neighboring Brighton Beach strolling the boardwalk in their Sunday best. Moreover, the annual Polar Bear Plunge on January 1 sees thousands of revelers greet the new year by diving into the frigid waters of the Atlantic. Run by the Coney Island Polar Bear Club ( www.polarbearclub.org), a winter bathing club founded in 1903, it's free and open to everyone as long as they've registered on the website—although donations are highly encouraged at registration, to benefit local nonprofits and the community. Amenities: toilets; food and drink. Best for: swimming; people-watching.

A former military site, this section of the Rockaway peninsula is still dotted with intriguing detritus. Two brutalist concrete batteries—Battery Harris West and Battery Harris East—are covered in graffiti and overgrown plant life, making for astonishing sights and choice photo backdrops. There are also two other batteries buried beneath the sand, as well as an underground missile silo, but you'll largely have to imagine what those looked like as they're blocked by a tall chain-link fence. Thanks to its relative inaccessibility (you really need a car, or be prepared to take a long subway ride followed by a bus), the beach itself remains blissfully empty for much of the year. Amenities: toilets. Best for: swimming; solitude.
