Essential Travel Tips
You absolutely MUST try St. Louis-style pizza and toasted ravioli. Imo's Pizza is the classic spot for thin-crust, Provel cheese pizza, and almost any Italian restaurant will have delicious toasted ravioli. Don't be surprised by the square cut – it's part of the charm!
While St. Louis has public transport (MetroLink light rail and buses), a car is highly recommended for exploring beyond the immediate downtown area. If you're staying centrally and plan to hit attractions like the Arch, City Museum, and Forest Park, ride-sharing apps like Uber and Lyft are readily available and convenient.
Many of St. Louis's best attractions are free! Forest Park, home to the zoo, art museum, and Missouri History Museum, offers free general admission to all its institutions. Pack a picnic to enjoy in the park and save even more on your visit.
St. Louisans are proud of their city's history and architecture. When visiting neighborhoods like Lafayette Square or the Central West End, take a moment to appreciate the beautiful Victorian homes and historic buildings. Don't be afraid to strike up a conversation with locals; they're usually happy to share their favorite spots.
Pack layers, especially if you're visiting in the spring or fall. St. Louis weather can be quite unpredictable, with warm days quickly turning cool, particularly near the riverfront. Comfortable walking shoes are a must, as you'll likely be doing a lot of exploring on foot.
Like any major 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.
