Coney Island Beach
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.
