Top Things to Do

Ascend the Gateway Arch at Dawn

Experience the Gateway Arch not just as a monument, but as a gateway to the sky. Take the tram ride to the top just as the sun begins to paint the horizon, casting a warm glow over the Mississippi River and the city waking below. The enclosed pods offer a unique perspective as you journey to the apex.

Explore the Delmar Loop's Eclectic Charm

Wander down the Delmar Loop, a vibrant street alive with independent boutiques, vintage shops, and a legendary live music scene. Catch a show at The Pageant or follow the 'St. Louis Walk of Fame' stars embedded in the sidewalk, celebrating local legends like Maya Angelou and Chuck Berry.

A Culinary Journey Through The Hill

Immerse yourself in St. Louis's Italian heritage on The Hill, a neighborhood brimming with authentic trattorias and bakeries. Savor a plate of toasted ravioli, a St. Louis specialty, at a family-run restaurant, and don't leave without grabbing some cannoli from a local pastry shop.

Discover the Missouri Botanical Garden's Tranquil Oasis

Escape to the Missouri Botanical Garden, a sprawling urban sanctuary featuring diverse plant collections and stunning themed gardens, including the Japanese Garden. Visit during spring for the peak bloom of azaleas and tulips, or in summer to wander through the lush Climatron geodesic dome.

Essential Travel Tips

food

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. Grab a pie from Imo's Pizza, our local institution, for the authentic experience.

transport

While St. Louis has public transport (MetroLink light rail and buses), it's not as comprehensive as some larger cities. For exploring beyond the immediate downtown and Forest Park areas, renting a car or using ride-sharing services like Uber/Lyft will be much more convenient and save you time.

money

Take advantage of free attractions! Forest Park is home to the Saint Louis Zoo, Saint Louis Art Museum, and Missouri History Museum, all of which offer free general admission. The Citygarden downtown is also a beautiful free sculpture park.

culture

Embrace the 'St. Louis pause.' While generally friendly, locals can sometimes be a bit reserved initially. Don't be discouraged if someone doesn't immediately strike up a conversation; a polite smile and a simple 'hello' often open the door to genuine warmth.

packing

Pack layers, no matter the season. St. Louis weather can be unpredictable; summers are hot and humid, while winters are cold and can bring snow. Even in spring and fall, mornings can be chilly, and evenings cool down significantly, so a light jacket or sweater is always a good idea.

safety

Be aware of your surroundings, especially at night. Stick to well-lit areas and popular districts like the Central West End or downtown when exploring after dark. Like any city, petty theft can occur, so keep valuables secure and out of sight.

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

Getting Around St. Louis, Missouri, USA

MetroLink Light Rail

St. Louis's light rail system is a convenient way to connect the airport to downtown and several key neighborhoods. It's ideal for avoiding traffic when arriving or departing, or for reaching attractions like the Arch or Busch Stadium without parking hassles.

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

MetroBus

The extensive MetroBus network covers most of the city and surrounding areas, offering a budget-friendly option for reaching destinations not served by the MetroLink. It's best for shorter hops within neighborhoods or for those on a tight budget who have time to spare.

Cost:$2.50 per ride, exact change required if paying cash.
Tip:Use the 'Metro Transit' app to plan your route and check for delays. Don't wait for the bus at the very edge of the sidewalk; stand back a bit so the driver can see you clearly. Buses can be crowded during peak hours, so be prepared for a close fit.

Ride-Sharing Services (Uber/Lyft)

Uber and Lyft are ubiquitous in St. Louis and offer door-to-door service throughout the city and its suburbs. This is the most flexible option for getting directly to your destination, especially if you're traveling with luggage or in a group.

Cost:Varies by demand and distance, typically $10-$30 for most city trips.
Tip:Always double-check your driver's name and car model against the app before getting in. Surge pricing can significantly increase costs during major events or rush hour; consider booking slightly in advance if possible. Be polite and thank your driver – a little courtesy goes a long way.

Taxis

While ride-sharing is more popular, taxis are still available in St. Louis, particularly around the airport, major hotels, and downtown. They can be a reliable option if you prefer a traditional service or if ride-sharing apps are experiencing high demand.

Cost:Metered fares, typically starting around $3-$5 plus per mile charges.
Tip:You can often hail a taxi downtown or find them at designated taxi stands. If you need one from your hotel, ask the concierge to call one for you. Tipping is customary, similar to ride-sharing services.

Biking (City Scoot/Lime)

Electric scooters and bikes from companies like City Scoot and Lime are scattered throughout the city, offering a fun and eco-friendly way to explore. They're perfect for short distances between attractions in walkable neighborhoods like the Central West End or downtown.

Cost:Typically a small unlock fee ($1) plus per-minute charges ($0.30-$0.40/minute).
Tip:Download the respective apps (City Scoot, Lime) and create an account beforehand. Never ride on sidewalks where prohibited, and always park responsibly in designated areas to avoid fines and annoyance from locals. Be mindful of St. Louis's hills, which can make longer rides more challenging.

Walking

Many of St. Louis's most popular attractions, especially downtown and in neighborhoods like the Central West End, are quite walkable. This is the best way to soak in the local atmosphere and discover hidden gems you might otherwise miss.

Cost:Free!
Tip:Wear comfortable shoes! St. Louis can be surprisingly spread out, so plan your walking routes. Be aware of pedestrian signals and crosswalks, and don't assume drivers will always yield, especially outside of busy intersections. Staying hydrated is key, particularly during the hot summer months.
