Your Complete Guide to Flying to St. Louis, Missouri
St. Louis sits on the western bank of the Mississippi River, a city of 300,000 that was once the Gateway to the American West — the launching point for the Lewis and Clark Expedition and generations of westward-bound settlers. The iconic Gateway Arch, soaring 630 feet above the riverfront, commemorates this profound role in American expansion and remains the tallest man-made monument in the United States. St. Louis’s civic pride in its extraordinary collection of free cultural institutions is genuine and well-founded — the Saint Louis Art Museum, Missouri History Museum, and Saint Louis Science Center are all completely free.
The Cardinals’ Busch Stadium on the downtown riverfront is among the most beautiful ballparks in baseball, and the Anheuser-Busch Brewery, birthplace of Budweiser, offers tours through one of the most storied industrial complexes in American commercial history.
