Standing 192 metres high and constructed completely of stainless steel, the Gateway Arch greets visitors on St. Louis flights every year. Prior to its formation in 1965, St. Louis welcomed travellers from all over the world who were heading westward in search of new opportunities and a new life. In the early 1900s, the Show Me State hosted the World’s Fair and as a result, witnessed the beginning of the city’s innovation and technology boom.

Visitors booking flights to St. Louis today have a plethora of options at their fingertips. The city is blanketed with history, but also rich in entertainment. Travellers book flights to St. Louis every summer for one of the best Independence Day celebrations in the nation. Take a tour around downtown St. Louis and visit the Anheuser-Busch Brewery and Busch Stadium, home of MLB St. Louis Cardinals.

St. Louis climate

St Louis has moderate, seasonal weather, but storms can occur at any time of the year. July and August are the hottest and most humid months of the year, and January and February are cold, usually with snow. Winter temperatures range from below 0 to 13 degrees (C), while summers have daily temperatures of between 14 to 32 degrees. 

Getting around St. Louis

You won’t need a car in downtown St Louis. You can get almost anywhere downtown with the St Louis MetroLink, which hits most of the area’s tourist attractions. There are even some shuttle buses connecting the MetroLink stations to the attractions. MetroBus, which is part of the same system, can get you farther out into the city. Rent a car if you’d like. St Louis is easy to navigate and you can take the highways out to top tourist neighbourhoods like University City, Central West End and Clayton. Most hotels and tourist attractions have a taxi stand if you need a cab. You can also call for a taxi ahead of time. 

What is good to know if travelling to St. Louis?

  • Independence Day is celebrated with style in St. Louis. Grab a blanket and a couple chairs and head down to the riverfront for Fourth of July festivities. Grab a spot underneath the Arch and enjoy the spectacle. From people watching, to concerts and outdoor vendors and markets, there is much to do to celebrate America’s birthday. And of course, an amazing fireworks display happens on the riverfront.
  • St. Louis’ Soulard Market Place is home to the best outdoor markets in the city, and also one of the best Mardi Gras party’s in the Midwest.
  • The Butterfly Garden in St. Louis’ suburb, Chesterfield, is a must-see for travellers of any age. Located in Faust Park about 30 minutes west of St. Louis City, the Butterfly Garden is a delight for everyone.
  • You don’t have to be a baseball fan to appreciate Busch Stadium. Take a tour of the Stadium or take in a game.
  • Beer lovers know St. Louis as the home of Anheuser-Busch. Brewed right in the city center, the Anheuser-Busch Brewery offers daily tours, and of course, beer tastings. 
  • When is the best time to fly to St. Louis?

    Peak Season Summers in St. Louis are hot and humid, but this is also the best time to visit if you want to take part in the riverfront activities. St. Louis is a big baseball town, and the St. Louis Cardinals draw thousands of fans a year. If you’re planning to visit St. Louis during the spring and summer seasons, book flights early and make accommodations ahead of time. The city gets full fast. Off Season St. Louis is prone to long, cold winters.  The city all but shuts down during the wintertime and while many tourist attractions are open to the public, none of the outside activities are much fun in the snow. However, if you’re heading to St. Louis for some football time or to explore the excellent museums, you’re likely to find a cheap flight to St. Louis in the winter.
