St. Louis travel tips
1) Do you like Budweiser beer? Then it will be interesting for you to visit the largest American brewery Anheuser-Busch in St. Louis | The Anheuser-Busch Brewery is the largest brewer in the United States. The company owns 12 breweries in the country and is considered the largest theme park operator. During a factory tour, you will also see the largest herd of Clydesdales – 250 Scottish draught horses. The brand produces Budweiser, Michelob, Busch, and Tequiza fruit beers. The visit to the brewery is free. |

2) Watch out in St. Louis and keep an eye on your belongings | According to recent polls, St. Louis is considered one of the most dangerous cities in America. But an ordinary tourist is unlikely to face any problems. Better keep an eye on your belongings, watch out for pickpockets, and avoid districts like Peabody-Darst-Webbe and Old North Saint Louis in the evenings. |
3) Having your own wheels makes getting around St. Louis much easier | Saint Louis is one of those American cities where it is really worth renting a car due to the long distances. Several major car rental companies are located right at St. Louis Airport. However, please note that for every 2 hours of parking in the city centre, you will pay $1.50 to $25. |
