Take a 630-foot ride to the top of this world-famous stainless steel monument for the finest views in the Gateway City. While you’re there, be sure to make time to explore the on-site museum, which traces over 200 years of our region’s history in six themed exhibit areas. Visitors to the Gateway Arch National Park can also hop aboard a 19th century paddle-wheel boat replica for a narrated cruise down the mighty Mississippi or soar above the city on a helicopter tour.
