Top Things to Do

Ascend the Gateway Arch at Dawn

Beat the crowds and witness the city awaken from the apex of the Gateway Arch. The tram ride itself is a unique experience, and the panoramic views of the Mississippi River and St. Louis skyline are unparalleled in the soft morning light. Consider booking your tickets online in advance, especially during peak season.

Explore the Delmar Loop's Eclectic Charm

Wander down the Delmar Loop, a vibrant street brimming with independent boutiques, vintage shops, and a legendary live music scene. Grab a bite at Fitz's, a classic diner known for its root beer and visible bottling operation, or catch a show at The Pageant. This is the heart of St. Louis's bohemian spirit.

Discover the City Museum's Whimsical Wonders

Unleash your inner child at the City Museum, an architectural playground built from reclaimed materials. Climb through airplane fuselages, slide down ten-story slides, and explore the surreal, multi-level art installations. It's an adventure for all ages, and visiting on a weekday can offer a more relaxed exploration.

Savor Toasted Ravioli at The Hill

No trip to St. Louis is complete without indulging in its signature dish: toasted ravioli. Head to The Hill, the city's historic Italian neighborhood, and choose from numerous trattorias like Charlie Gitto's or Zia's. The crispy exterior and savory filling are a delightful surprise, best enjoyed with a local craft beer.

Essential Travel Tips

food

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 virtually every Italian restaurant will have toasted ravioli – it's a unique local appetizer you won't find elsewhere. Don't be afraid of the Provel, it's a game-changer!

transport

While St. Louis has public transport (MetroLink light rail and buses), a car is highly recommended for exploring beyond the immediate downtown and Forest Park areas. Consider ride-sharing services like Uber or Lyft for nights out or if you're staying in a more central neighborhood like the Central West End, as parking can be tricky and expensive downtown.

money

Take advantage of St. Louis's incredible free attractions! Forest Park alone houses the Zoo, Art Museum, History Museum, and Missouri Botanical Garden (some special exhibits may have fees, but general admission is often free or very affordable). Pack a picnic to enjoy in the park and save on lunch costs.

culture

Embrace the 'St. Louis pause.' Locals tend to be friendly but can be a bit reserved initially. A simple 'hello' or 'good morning' when passing someone on a trail or in a shop goes a long way and often opens the door to a more genuine interaction. Don't be surprised if people strike up conversations at Cardinals games – it's part of the experience!

packing

Pack layers, no matter the season! St. Louis weather can be unpredictable. Summers are hot and humid, while winters can be quite cold with occasional snow. Even in spring and fall, mornings can be chilly while afternoons warm up considerably, so a light jacket or sweater is always a good idea.

safety

Be aware of your surroundings, especially in less populated areas or at night. Stick to well-lit streets and popular tourist spots after dark. While generally safe, like any major city, petty theft can occur, so keep valuables secure and out of sight, particularly in crowded areas or when using public transport.

💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Getting Around St. Louis, USA

MetroLink Light Rail

St. Louis's light rail system is a clean and efficient way to connect the airport to downtown, the Central West End, and even into Illinois. It's ideal for avoiding traffic when heading to major attractions or arriving/departing the airport.

Cost:$2.50 per ride, with daily and monthly passes available.
Tip:Download the 'Metro Transit' app for real-time schedules and fare information. A common mistake is assuming it goes everywhere; it's great for key corridors but doesn't cover all neighborhoods. Be aware of your surroundings, especially late at night, and keep valuables secure.

Metro Bus System

The extensive bus network covers most of the city and surrounding areas, offering a more granular reach than the MetroLink. Use it to explore neighborhoods not directly served by the rail, like The Hill or Tower Grove.

Cost:$2.00 per ride, with transfers included within a certain timeframe.
Tip:Google Maps or the 'Metro Transit' app are essential for planning routes and checking arrival times. Buses can sometimes run behind schedule, so build in extra time. Avoid standing too close to the front of the bus unless you're boarding or alighting; give passengers space.

Ride-Sharing Services (Uber/Lyft)

These services are ubiquitous in St. Louis and offer door-to-door convenience for getting around the city, especially for groups or when traveling to destinations not easily accessible by public transit. They are a good option for evenings out or when carrying luggage.

Cost:Variable, typically starting around $10-$15 for short rides, increasing with distance and surge pricing.
Tip:Be patient during peak hours or major events, as surge pricing can significantly increase fares and wait times. Always double-check the license plate and car model against the app before getting in to avoid entering the wrong vehicle – a surprisingly common error.

Taxis

While less common than ride-sharing, taxis are still available and can be hailed on the street in busy areas or booked in advance. They are a reliable option if you prefer a traditional service or if ride-sharing apps are experiencing issues.

Cost:Metered fares, typically starting around $3-$5 with additional charges per mile and waiting time.
Tip:Have cash or a credit card ready, as some smaller taxi companies might have limitations. It's good practice to confirm the fare estimate with the driver before starting your journey, especially for longer trips.

Biking (City Scoot/Lime)

Electric scooters and bikes are scattered throughout the city, offering a fun and flexible way to cover short to medium distances, especially in downtown, Forest Park, and the Central West End. They're perfect for exploring parks or hopping between nearby attractions.

Cost:Typically a small unlock fee (around $1) plus a per-minute charge (around $0.30-$0.40).
Tip:Download the respective apps ('City Scoot' or 'Lime') and familiarize yourself with the rules of the road for scooters. A common mistake is riding on sidewalks where prohibited; stick to bike lanes or streets. Always park responsibly, ensuring you don't block pedestrian pathways.

Walking

Many of St. Louis's most popular areas, like the Gateway Arch National Park, downtown, and the Central West End, are very walkable. It's the best way to soak in the atmosphere and discover hidden gems you might miss otherwise.

Cost:Free!
Tip:Wear comfortable shoes! St. Louis can be surprisingly hilly in some areas. Check the weather forecast before you set out, as summers can be hot and humid, and winters can be cold. Stay aware of your surroundings and traffic, especially when crossing streets.
