Sunken Meadow State Park (officially Governor Alfred E. Smith State Park) is a 1,287-acre coastal gem on Long Island’s north shore, where three miles of beach meet the calm waters of the Long Island Sound, glacier-formed bluffs rise 70 feet above the shore, and a lush salt marsh gives the park its evocative name. Just an hour from New York City, Sunken Meadow is one of Long Island’s most beloved parks — and the northern starting point of the Long Island Greenbelt Trail.

The park’s varied terrain — wooded hills, salt marshes, bluffs, shoreline — creates surprisingly diverse hiking for Long Island. The famous “Cardiac Hill” is a notable incline used in high school cross-country races.

The Sunken Meadow

The park’s namesake sunken meadow is a picturesque salt marsh where Sunken Meadow Creek meets the Sound. Bridges cross the creek, and the marsh habitat supports diverse birdlife including herons, egrets, and shorebirds.
