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.
Explore the Delmar Loop's Eclectic Charm
Wander down the Delmar Loop, a vibrant street brimming with independent boutiques, vintage shops, and diverse eateries. Catch a show at The Pageant or follow the St. Louis Walk of Fame, a sidewalk tribute to famous locals, for a taste of the city's creative pulse.
Savor a Toasted Ravioli at The Hill
Venture into The Hill, St. Louis's historic Italian neighborhood, and indulge in the city's unofficial culinary ambassador: toasted ravioli. While many restaurants serve it, try a classic spot like Charlie Gitto's for an authentic taste of this crispy, cheesy delight.
Discover the Magic of the City Museum
This isn't your typical museum; it's a fantastical playground built from repurposed architectural and industrial objects. Climb through giant slides, explore a multi-story ball pit, and discover hidden nooks and crannies – it's an adventure for all ages.
💡 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, crispy, square-cut, and topped with Provel cheese (a processed blend of provolone, swiss, and cheddar). Grab a pie from Imo's Pizza, our local institution, for the authentic experience – just be prepared for a cheese pull unlike any other!
While St. Louis has public transport (MetroLink light rail and buses), it's best explored by car, especially if you want to venture outside the immediate downtown area. Consider renting a car or using ride-sharing services like Uber/Lyft for flexibility, particularly for visiting attractions like the Zoo or the Missouri Botanical Garden.
Take advantage of free attractions! The St. Louis Zoo, Saint Louis Art Museum, Missouri History Museum, and the Science Center all offer free general admission. Pack a picnic to enjoy in Forest Park, saving you money on food while soaking in the city's green heart.
Embrace the 'St. Louis pause.' Locals tend to be friendly and approachable, but don't be surprised if conversations start with a bit of quiet observation before diving in. When asking for directions, most people are happy to help, but a polite 'excuse me' goes a long way.
Pack layers, no matter the season. St. Louis weather can be notoriously unpredictable, with hot, humid summers and cold, snowy winters. Even in spring and fall, mornings can be chilly, so a light jacket or sweater is always a good idea to have on hand.
Be aware of your surroundings, especially downtown 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 late. Stick to popular entertainment districts like the Central West End or the Delmar Loop after dark.
