Top Things to Do
Ascend the Gateway Arch at Dawn
Skip the midday crowds and book the first tram ride to the top of the Gateway Arch. Witnessing the city awaken from 630 feet up, with the Mississippi River shimmering below, is a truly magical experience. The tram ride itself, a unique pod system, is part of the adventure.
Explore the City Museum's Architectural Playground
This isn't your typical museum; it's a surreal, multi-story playground crafted from reclaimed architectural elements. Climb through airplane fuselages, slide down ten-story slides, and discover hidden nooks and crannies. Go on a weekday evening for fewer crowds and a more adventurous vibe.
Savor Toasted Ravioli in The Hill
Venture into The Hill, St. Louis's historic Italian neighborhood, and indulge in the city's unofficial culinary mascot: toasted ravioli. Many restaurants here claim to have invented it, so try a few to find your favorite crispy, cheesy delight. Enjoy it with a glass of local wine for the full experience.
Wander Through the Missouri Botanical Garden's Japanese Garden
Escape to the tranquil Seiwa-en Japanese Garden within the Missouri Botanical Garden, a meticulously designed oasis of calm. Visit during spring for the cherry blossoms or autumn for the vibrant foliage. The gentle sounds of water and the carefully sculpted landscapes offer a peaceful respite.

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 uses Provel cheese, which is a processed blend of provolone, Swiss, and cheddar. It's a love-it-or-hate-it thing, but you can't visit without giving it a shot at places like Imo's or Pirrone's.
While St. Louis has a MetroLink light rail system, it's not as extensive as in some other major cities. For exploring neighborhoods like The Hill or Tower Grove, consider using ride-sharing services like Uber or Lyft, or even renting a bike through a service like Lime or Bird if the weather's nice. Parking can be a hassle downtown, especially during events.
Take advantage of free attractions! The City Museum, while it has an admission fee, is an absolute must-do and worth every penny for its unique, interactive art installations. Many of our beautiful parks, like Forest Park (home to the zoo, art museum, and Missouri History Museum), offer free admission to their main attractions.
Don't be surprised if St. Louisans are fiercely proud of their city and its history. Strike up conversations with locals at a Cardinals game or while exploring neighborhoods like Soulard – you'll likely get some fantastic, unsolicited recommendations for hidden gems. We also have a unique dialect; listen for terms like 'w Setter' (a type of sandwich) or 'bubbler' (a water fountain).
Pack layers, no matter the season. St. Louis weather can be notoriously unpredictable. Summers are hot and humid, while winters can bring snow and freezing temperatures. Even in spring and fall, you might experience a wide temperature swing from morning to afternoon, so a light jacket or sweater is always a good idea.
Like any city, be aware of your surroundings, especially at night. Stick to well-lit areas and be mindful of your belongings. While most tourist areas are safe, it's always wise to research specific neighborhoods if you plan to venture off the beaten path. The MetroLink is generally safe, but be aware of your surroundings, 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.

Frequently Asked Questions
When's the absolute best time to visit St. Louis if I want to enjoy outdoor activities without melting?
For my money, late April through early June is prime time in St. Louis. The weather is usually gorgeous, perfect for exploring Forest Park or catching a Cardinals game without the oppressive summer heat and humidity. Plus, the city's blooming with spring flowers, making it extra picturesque.
Beyond the Arch, what's a must-do that most tourists miss?
You absolutely have to check out the City Museum. It's not your typical museum; it's a wild, interactive playground built from reclaimed architectural and industrial objects. Kids and adults alike can climb through caves, slide down multi-story slides, and explore all sorts of quirky installations – it's pure, unadulterated fun and unlike anything else.
How easy is it to get around St. Louis without a car?
It's doable, but having a car definitely makes things easier, especially if you want to explore neighborhoods outside the immediate downtown and Central West End. The MetroLink light rail connects the airport to downtown and some key areas, and ride-sharing services are readily available. However, for spontaneous trips to places like Lafayette Square or South Grand, a car or frequent Uber/Lyft rides are your best bet.
What's the deal with St. Louis barbecue? Is it different?
Oh, St. Louis BBQ is its own glorious thing! We're famous for our St. Louis-style ribs, which are spare ribs that have been trimmed down and are typically grilled and slathered in a sweet, tangy tomato-based sauce. Don't expect a ton of smoky complexity like in Texas; it's more about that tender meat and sticky, sweet glaze. Pappy's Smokehouse and Sugarfire are local favorites, but don't be afraid to try smaller, neighborhood joints.
Are there any local quirks or customs I should be aware of?
One thing you'll notice is the distinct St. Louis accent, often described as a 'hillbilly' or 'Midwestern' drawl, though locals might not hear it! Also, be prepared for the sheer number of 'hill' neighborhoods – areas like The Hill are famous for their Italian heritage and incredible food. Just embrace the friendly, down-to-earth vibe; people are generally very welcoming.
What's a great spot for live music that isn't a huge stadium?
For a more intimate live music experience, head to The Pageant in the Delmar Loop. It's a fantastic mid-sized venue that hosts a wide range of national touring acts, from indie rock to blues. The atmosphere is always buzzing, and you get a great view of the stage no matter where you stand.
