St. Louis is a city that celebrates big. From its legendary Mardi Gras (second only to New Orleans) to the grand Fourth of July spectacle at the Arch, the city's event calendar is packed with genuine traditions — not manufactured photo ops, but festivals that locals have been attending for generations. Here is the essential annual guide.
January & February: Mardi Gras Season
February / March
Mardi Gras in Soulard
St. Louis hosts the second-largest Mardi Gras celebration in the United States, and anyone who has attended can confirm that it earns the distinction. The historic Soulard neighborhood — cobblestone streets, brick rowhouses, and French Creole architecture dating to the late 1700s — provides a genuinely historic backdrop for a multi-week festival that culminates on Fat Tuesday.
The main parade attracts more than 150,000 attendees. The Dog Parade (dogs in costume, a St. Louis institution) typically draws 2,000+ four-legged participants. The surrounding bars — Molly's, McGurk's, Venice Cafe, Hammerstone's — become pilgrimage sites. Even visitors who don't drink find the neighborhood energy during Mardi Gras season unlike anything else in the Midwest.
Pro tip: The neighborhood walking festivals in the two weeks before Fat Tuesday are often more authentic than the big parade day itself. Get there before the out-of-towners arrive.
March: St. Patrick's Day
March
St. Patrick's Day Parade
The St. Louis St. Patrick's Day Parade is among the oldest and largest in the country, drawing roughly 100,000 spectators along Tucker Boulevard. The tradition dates to 1820, making it one of the longest-running parades in America. The Dogtown neighborhood on the city's west side also throws a parallel celebration that many locals prefer for its neighborhood character and proximity to local bars like Seamus McDaniel's and O'Connell's Pub.
April & May: Spring Festivals
April / May
St. Louis Greek Festival
Hosted by the Assumption Greek Orthodox Church in Creve Coeur, the St. Louis Greek Festival is a beloved three-day celebration of food, music, and dance. The food — pastitsio, spanakopita, loukoumades, roasted lamb — is genuinely excellent, the dancing is participatory, and the wine flows freely. Ticket prices are modest; food and beverages are additional.
May
Cherokee Street Art Walk
An annual celebration of the street art and gallery culture along Cherokee Street, one of St. Louis's most diverse and creative corridors. Gallery openings, live music, and food vendors fill the street on a Saturday evening each May. Free admission; the galleries encourage entry without purchase pressure.
June: Festival Season Opens
June
Whitaker Music Festival (Begins)
The Missouri Botanical Garden's beloved Friday-evening concert series runs from late May through August. Performers span jazz, blues, folk, and classical — all on the great lawn of one of the world's finest botanical gardens. Gates open at 5pm; concerts begin at 7pm. The Garden is open during concerts, so attendees can explore the Japanese Garden and rose garden before the music starts. General admission to the Garden is required; no additional concert fee.
June
Cardinals Baseball at Busch Stadium
St. Louis is one of the most devoted baseball cities in America. The Cardinals have won 11 World Series championships, and fans take the game seriously in ways that most American cities have forgotten. Busch Stadium is a beautiful park with good sightlines from every seat, genuine local food options (toasted ravioli, Imo's pizza, Ted Drewes frozen custard), and a downtown location that makes pre- and post-game dining easy. Tickets range from $20 (upper deck) to premium for the best seats; the experience punches far above its price point.
July: The Fourth at the Arch
July
Fair St. Louis
The Fourth of July celebration at the Gateway Arch — officially Fair St. Louis — is one of the largest Independence Day events in the country, drawing 500,000+ attendees over three days. The event includes major concert headliners, the VP Fair's legacy traditions (historically one of the world's largest air shows), an air show over the Mississippi, and the fireworks display at the Arch, which is among the most spectacular in the nation. The Arch grounds are free and open; the air show and concerts require tickets for premium areas but can be watched from the public riverfront.
August & September: Late Summer
August
Taste of St. Louis
A three-day outdoor food festival in a park setting featuring restaurants from across the city. Admission is free; food and drink are purchased via vouchers. The lineup typically includes 30-40 restaurants representing the city's range from toasted ravioli to Korean BBQ to craft cocktails. Live music on multiple stages runs throughout the weekend.
September
St. Louis Art Museum Late Night
The Art Museum extends its hours on Friday evenings in September, often pairing extended gallery access with live music, art-making workshops, and themed bar programming. The combination of world-class art and social atmosphere makes this one of the city's most distinctive recurring events. Free admission to the permanent collection; bar and event programming may carry fees.
October: Fall in St. Louis
October
St. Louis Oktoberfest in Soulard
The Soulard neighborhood returns in October for an Oktoberfest celebration anchored around German beer culture and the neighborhood's historic biergartens. Free street access; paid tent and premium options available. Local breweries and German restaurants participate alongside the larger national beer brands. Polka bands, costume contests, and stein-holding competitions complete the atmosphere.
October
Cardinals Postseason (When Applicable)
When the Cardinals make the playoffs — which they do more often than most franchises — St. Louis transforms. Bars near Busch Stadium sell out, the city's collective attention narrows to a point, and the energy downtown is unlike anything in the regular season. Check October schedules; playoff tickets require advance purchase and sell out quickly.
November & December: Holiday Season
November / December
Zoo Lights at the Saint Louis Zoo
One of the most acclaimed free holiday light displays in the United States, Zoo Lights transforms the Saint Louis Zoo into a winter wonderland from mid-November through late December. More than a million lights illuminate the animals' habitats and the zoo's paths. Warm beverages, holiday music, and the surreal experience of walking among sleeping zoo animals in the evening make this a beloved local tradition. The event is free; some evenings may have premium ticketed options for special programming.
December
St. Louis Christmas Markets
The city's German heritage surfaces again at Christmas, with markets at several locations including Kiener Plaza downtown and at various neighborhood commercial districts. Vendors sell handmade gifts, German food, and holiday items. Soulard Market also runs a holiday market. The Gateway Arch grounds offer holiday programming through December.
Planning Your Visit Around Events
St. Louis events fill hotel rooms quickly — especially Mardi Gras, Fair St. Louis, and major Cardinals home series. Book accommodations 2-3 months in advance if you're attending any of the major events. Most festivals provide free event information through the Explore St. Louis visitor bureau, the St. Louis Post-Dispatch calendar, and the Riverfront Times weekly listings.
For Cardinals tickets, StubHub and SeatGeek typically offer better prices than face value for weekday games. Weekend games against division rivals sell out; plan accordingly.
