Pelham Bay Park
You thought Central Park was massive? Pelham Bay Park comes in at over three times the size of its Manhattan equivalent, making it NYC's largest park. Its nearly 2,800 acres include just about everything you can imagine: hiking trails, barbecue areas, playgrounds, every type of athletic field/court/course/track, a historic mansion, a dog run, and 13 miles of shoreline primarily along the Eastchester and Pelham bays. Orchard Beach is the most notable waterfront area—and for good reason—but you don't need sand to enjoy the area's many waterways. Just about any of the park's edges will tickle your fancy, but Hunter Island (which is actually a peninsula) steals the show.
