Airport Details: From YUL, Montréal To STL, Lambert - St. Louis International Airport

St. Louis is a character-rich city with a pleasing array of unique neighbourhoods, including Grand Center, the city's arts and entertainment district, and The Hill, home to authentic Italian eateries. A bounty of historical draws and natural attractions can also be found here; as a matter of fact, 1,300-acre Forest Park is hundreds of acres bigger than New York City's Central Park and includes a science centre and golf course. However, no trip to The Gateway to the West would be complete without visiting the impressive Gateway Arch, the tallest man-made monument in the United States.
