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.
💡 Travel Tip: For the best value on hotels during this season, check current rates on Trip.com.
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. Grab a pie from Imo's Pizza, our local institution, for the authentic experience.
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.
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.
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.
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.
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.
