Gateway Arch National Park
St. Louis, MO · Gateway to the West, Missouri
Gateway Arch is the most unusual national park in the country, a single 630-foot stainless-steel curve on the St. Louis riverfront that doubles as the nation's tallest monument. Ride the tram up inside one leg to an observation deck for a long look over the Mississippi River and the city, then walk the riverside grounds and the museum tracing America's westward expansion. At about 91 acres it is the smallest national park, easily seen in a day.
