Essential Travel Tips
You absolutely MUST try St. Louis-style pizza – it's thin, cracker-like crust, cut into squares, and often topped with Provel cheese. Grab a slice at Imo's Pizza, a local institution, and don't be surprised if it's a bit different from what you're used to, but it's a true taste of the city!
While St. Louis has public transport, renting a car or using ride-sharing services like Uber/Lyft will give you the most flexibility, especially if you plan to explore beyond the immediate downtown area. Many of the best neighborhoods and attractions, like Forest Park or the Hill, are spread out.
Take advantage of the free attractions! Forest Park is home to world-class institutions like the Saint Louis Art Museum and the Missouri History Museum, both of which offer free general admission. You can easily spend a whole day exploring without spending a dime on entry fees.
Don't be afraid to strike up conversations with locals, especially at a Cardinals baseball game or a neighborhood pub. St. Louisans are generally friendly and proud of their city; ask for recommendations for the best BBQ joint or a hidden gem park, and you'll likely get some great insider tips.
Pack layers, no matter the season. St. Louis weather can be unpredictable; summers are hot and humid, while winters can be quite cold with snow. Even in spring and fall, you might experience significant temperature swings throughout the day.
Like any major city, be aware of your surroundings, especially at night. Stick to well-lit areas, keep valuables secure, and be mindful of your personal belongings, particularly in crowded tourist spots or on public transportation.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

When's the absolute best time to visit St. Louis, considering both weather and crowds?
For a sweet spot of pleasant weather and manageable crowds, aim for late April to early June, or September to mid-October.

Plus, you'll likely find better deals on accommodations during these shoulder seasons.
Beyond the Gateway Arch, what's a must-see that most tourists miss?
You absolutely have to explore the City Museum. It's not a traditional museum with quiet exhibits; it's a wildly imaginative, interactive playground built from reclaimed architectural and industrial objects. Think climbing through a giant Slinky or sliding down a 10-story spiral slide – it's an unforgettable experience for all ages, and a true St. Louis original.
How do I get around St. Louis without a car?
St. Louis has a decent public transit system, primarily the MetroLink light rail and MetroBus.
