There are actually two places that come to mind when you hear Rockefeller Park in New York City. The first, and most likely what you're referring to, is Rockefeller State Park Preserve, located about 30 miles north of Manhattan in Westchester County.
This expansive park offers a peaceful escape from the urban jungle. Managed by the New York State Office of Parks, Recreation and Historic Preservation, the Rockefeller State Park Preserve is open to the public year-round, offering a chance to explore nature just outside of NYC.
The park itself was donated to the state by the Rockefeller family over a number of years, beginning in 1983. The property was once the home of the Rockwood Hall and Pocantico Hills estates of John D. Rockefeller and William Rockefeller.
The park encompasses over 1,700 acres of forests, fields, streams and wetlands. Visitors can enjoy hiking, biking, horseback riding, fishing and birdwatching. The park is also home to a number of historic features, including the Pocantico River, Swan Lake, and carriage roads built by the Rockefeller family in the early 20th century.
The second location that might be referred to as Rockefeller Park is actually a small green space located in Midtown Manhattan, right between Fifth and Sixth Avenues, nestled amongst the Rockefeller Center complex. While this isn't really a destination park, it does offer a brief respite from the hustle and bustle of the city. Visitors can relax on a bench, enjoy the seasonal flowers in the Channel Gardens, or grab a bite to eat from a nearby vendor.
So, depending on what you're looking for, there's a Rockefeller Park for you! If you're seeking a nature escape, head north to Westchester County. But if you just need a quick break in the middle of your Manhattan explorations, Rockefeller Center has you covered.
