The urban location makes Gateway Arch different then most other National Parks that seem to be located in remote areas of the country. The “Gateway to the West” is a 630-foot monument in St. Louis, Missouri. It’s constructed of 43,000 tons of concrete and steel making it the world’s tallest arch. Don’t miss the tram ride to the top! It’s not to be missed… well… unless you have claustrophobia… it’s comfortable, but very tight quarters! The Arch represents a gateway into the wild and wonderous American West.
