Essential Travel Tips
You absolutely MUST try St. Louis-style pizza and toasted ravioli! Iggy's and Imo's are the classic spots for the thin-crust, Provel cheese pizza, and Charlie Gitto's is a great place to start for toasted ravioli. Don't be surprised if the pizza is cut into squares – that's the St. Louis way!
While St. Louis has a MetroLink light rail system, it's not as comprehensive as in some other major cities. For exploring neighborhoods like The Hill or Forest Park, consider using ride-sharing services like Uber or Lyft, or even renting a bike if the weather's nice. Parking can be tricky and expensive downtown, so factor that into your plans.
St. Louisans are proud of their city, especially its blues music heritage and baseball team, the Cardinals. Catching a game at Busch Stadium is an iconic experience, even if you're not a huge baseball fan – the atmosphere is electric. Also, don't miss the live blues music scene, particularly in the Soulard neighborhood.
Many of St. Louis's best attractions are surprisingly affordable or even free! Forest Park, home to the zoo, art museum, and Missouri History Museum, offers free general admission to all its institutions. Take advantage of these incredible public resources to save money while experiencing the best of the city.
St. Louis experiences all four seasons, so pack accordingly. Summers can be very hot and humid, so light, breathable clothing is a must, along with sunscreen and a hat. Winters can be cold and snowy, so bring a warm coat, gloves, and a hat. Comfortable walking shoes are essential year-round for exploring the city's many parks and neighborhoods.
Like any city, be aware of your surroundings, especially at night. Stick to well-lit areas and avoid walking alone in unfamiliar neighborhoods after dark. The MetroLink is generally safe, but it's always wise to be vigilant, particularly during off-peak hours.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.
