Essential Travel Tips
You absolutely MUST try St. Louis-style pizza. It's thin, cracker-like crust, cut into squares (called a 'party cut'), and typically topped with Provel cheese. Grab a pie from Imo's Pizza – it's a local institution and the perfect introduction to this unique culinary experience.
While St. Louis has public transport, getting around is much easier with a car, especially if you plan to explore beyond the immediate downtown area. If you're sticking to the city center, the MetroLink light rail is efficient for reaching attractions like the airport, Busch Stadium, and the Delmar Loop.
Take advantage of free attractions! The City Museum, while it has an admission fee, is an incredible, unique experience for all ages. Many of our beautiful parks, like Forest Park (home to the zoo and art museum, both free!), offer fantastic entertainment without costing a dime.
Embrace the 'St. Louis Wave' when driving. If someone lets you merge or waves you on, a quick wave back is customary and appreciated. It's a small gesture that reflects the friendly, laid-back nature of the locals.
Pack layers, no matter the season. St. Louis weather can be notoriously unpredictable; a sunny morning can turn into a chilly afternoon. Comfortable walking shoes are also a must, as you'll likely be doing a lot of exploring on foot, especially in areas like Forest Park or the Delmar Loop.
Be aware of your surroundings, especially at night. While St. Louis is generally safe, like any major city, it's wise to stick to well-lit areas and avoid walking alone in unfamiliar neighborhoods after dark. Use ride-sharing services if you're unsure about transportation options.

Frequently Asked Questions
When's the absolute best time to visit St. Louis, and what should I pack for it?
Honestly, spring (April-May) and fall (September-October) are your sweet spots for St. Louis. The weather is usually gorgeous, perfect for exploring Forest Park or catching a Cardinals game without the sweltering summer heat or the biting winter chill. Pack layers – a light jacket or sweater is a must, even in summer evenings, and comfortable walking shoes are non-negotiable for all the exploring you'll do.
Beyond the Arch, what's a must-do that most tourists miss?
You absolutely have to spend a day in Forest Park. It's larger than Central Park and home to the zoo, art museum, history museum, and the Missouri Botanical Garden, all with free general admission! My personal favorite is wandering through the Jewel Box, a stunning Art Deco greenhouse, especially if you catch it when they have a special seasonal display.
How do I get around St. Louis without a car?
While a car offers the most flexibility, you can absolutely manage without one, especially if you're staying downtown or in neighborhoods like the Central West End. The MetroLink light rail connects the airport to downtown and some key areas, and there are bus routes that cover a lot of ground. For getting between neighborhoods or for shorter trips, ride-sharing services are readily available and generally quite affordable.
What's a quintessential St. Louis food experience I shouldn't miss?
You can't leave St. Louis without trying toasted ravioli – it's a local invention and surprisingly addictive! Most Italian restaurants serve them, but for the original experience, try Mama's on the Hill. Also, grab some St. Louis-style pizza, which is thin crust with Provel cheese; it's a love-it-or-hate-it situation, but you have to try it at least once!
Are there any local events or festivals that make visiting during a specific month extra special?
If you can swing it, visit in September for the Great Forest Park Balloon Race – it's a magical sight with dozens of hot air balloons launching at dawn. Also, the Loop Music Festival in The Loop neighborhood in late August is fantastic for live music and a vibrant street scene. Check local listings closer to your travel dates, as St. Louis always has something going on.
