The perimeter of Roosevelt Island in New York City is approximately 3.5 to 4 miles (about 6.4 km). The island is long and narrow, stretching about 2 miles from its northern tip at the Lighthouse Park to its southern tip at the Franklin D. Roosevelt Four Freedoms State Park. A paved, multi-use waterfront path runs nearly the entire circumference of the island, providing a flat and incredibly scenic route for runners and walkers. In 2026, this path is a "hidden gem" for those looking for unmatched views of the Manhattan skyline and the Queens waterfront without the crowds of Central Park. A brisk walk around the entire edge takes about 60 to 90 minutes. For a 2026 visitor, it is a peer-to-peer "pro-tip" to take the Roosevelt Island Tramway from 59th Street in Manhattan for a spectacular aerial view of the island before you begin your walk, or use the "F" train or NYC Ferry for a more traditional arrival at the island's central hub.
