If you've lived in Bethlehem through a few Augusts, you know the rhythm of Musikfest: ten days of free stages and ticketed headliners, and then it's over and the city exhales. So when the calendar flips to late September and the bagpipes start up on Main Street, it's easy to assume you're watching the same show return for an encore. You're not. What's actually happening this fall is two separate festivals, run by two separate organizations, occupying two different parts of the city, back to back to back, for three straight weekends. Confuse the map for one with the map for the other and you'll end up circling for parking in the wrong neighborhood entirely.
Here's the shape of it. The Celtic Classic Highland Games & Festival takes over Historic Downtown Bethlehem September 25 through 27, its 39th year running. The following Friday, Oktoberfest opens at SteelStacks on the South Side, then closes for five days and reopens for a second weekend, October 9 through 11, marking its 16th year. That's not one long festival with a pause in the middle. It's two distinct events that happen to fall on consecutive weekends, sharing a season but nothing else.
Why the Confusion Happens
Both events are free to attend. Both fill their host area with music, food vendors, and family programming. Both get lumped together in "things to do this fall" roundups that treat them as interchangeable autumn color. But the Celtic Classic is an open-street festival that spills across downtown blocks and the Colonial Industrial Quarter, built around Highland Field and a stretch of pedestrian paths and bridges near the Monocacy Creek. Oktoberfest, by contrast, is staged on the ArtsQuest campus at PNC Plaza, at the foot of the old Bethlehem Steel blast furnaces on the South Side. One is a festival that happens to your whole downtown. The other is a ticketless but gated event you walk into and out of at a defined entrance.
That distinction matters if you're trying to get dinner reservations near either site, or just trying to get through downtown on a Saturday without detouring around a parade route. The Celtic Classic's marquee moment, the Showing of the Tartan Parade, kicks off at Bethlehem City Hall at 11:30 a.m. on Saturday and marches to Highland Field, which means downtown streets around City Hall are functionally closed to normal traffic for that stretch of the morning. Oktoberfest doesn't touch that part of the city at all. Its congestion lives entirely around PNC Plaza and the SteelStacks parking areas, on the other side of town.
Three Weekends, Not One
Laid out on a calendar, the run looks like this:
- September 25 to 27 — Celtic Classic Highland Games & Festival, Historic Downtown Bethlehem. Five stages of Celtic music, the U.S. National Highland Games Championship at Highland Field, pipe band competitions at Piping Grove on Lehigh Street, Irish dance performances from the O'Grady Quinlan Irish Academy of Dance, and a Saturday morning 5K that starts at the Bethlehem Area Public Library and finishes at Sand Island.
- October 2 to 4 — Oktoberfest weekend one at SteelStacks. Four biergartens, the season's first Flip Cup Tournament, and the Yuengling Oktoberfest 5K on Sunday morning, which finishes runners with a mug of Yuengling Oktoberfest or root beer instead of a medal.
- October 9 to 11 — Oktoberfest weekend two. The Pennsylvania State Steinholding Championships, a second Flip Cup bracket, and a new addition this year, a bourbon tasting hosted by certified Bourbon Steward Matthew Peters alongside food from Levy Restaurants.
Seventeen days, three full festival weekends, zero overlap in location. If you live near downtown, your disruption window is a single weekend in late September. If you're closer to the South Side, yours is two weekends in October with a workweek breather in between.
What's Actually New This Year
The Celtic Classic's programming has settled into a familiar rhythm over 39 years, but Oktoberfest keeps adding wrinkles. This is its second year running the Flip Cup Tournament, teams of four competing bracket-style with cups filled with water rather than beer, winners walking away with ArtsQuest gift cards. The bourbon tasting is brand new, a ticketed 21-and-over add-on for people who've done the biergarten circuit before and want something else to do with a Saturday afternoon. And joining the entertainment lineup for the first time is Allentown-based performer Matt Ossiander, who works a Cyr Wheel, the large single-ring apparatus acrobats use for spinning stunts.
Meanwhile, the constant that hasn't changed in fifteen years is Heaven On A Bun, which has served its Bavarian burger, a pretzel roll topped with Swiss cheese, sauerkraut, and grilled onions, at every single Oktoberfest since it started. Thomas Stoudt, Executive Director of Lehigh Valley International Airport, which presents the festival, put the event's staying power this way in ArtsQuest's own announcement:
"Oktoberfest remains a must-see event at SteelStacks, bringing our communities together"
That's the kind of continuity that makes a fifteen-year vendor streak worth noting. It also tells you something about who's showing up. Oktoberfest reads as a return crowd, families who've made it a standing October tradition, whereas the Celtic Classic draws clan societies and dance and pipe band competitors from well outside the Lehigh Valley chasing a specific cultural connection.
If You're Skipping Both
Not everyone wants to spend three weekends navigating festival crowds, and you don't have to. But a few practical notes apply even if you're staying home. Oktoberfest is dog-friendly, so if your usual Saturday routine includes a walk near the SteelStacks campus in early October, expect more foot traffic and more dogs than a typical weekend. The Celtic Classic's parade route runs through the heart of downtown starting at 11:30 a.m. Saturday, so if you have a reason to be near City Hall that morning, plan around it rather than through it. And because Oktoberfest is genuinely two separate weekends rather than one continuous run, the South Side goes back to normal for the five weekdays between October 4 and October 9. That gap is worth knowing if you're deciding when to schedule anything South Side-adjacent, a dentist appointment, a delivery, a contractor visit, that you'd rather not compete with festival parking for.
If you're new to the neighborhood and still getting your bearings on where things happen and when, this is the kind of texture that doesn't show up on a map. The Historic Downtown and the South Side function almost like two different event calendars that happen to belong to the same city, and knowing which one is active on a given weekend saves you the guesswork.
The Takeaway for Anyone Keeping Score
The instinct to treat "festival season" as one undifferentiated stretch of the calendar is understandable after a summer of Musikfest, but it undersells what's actually happening this fall. Bethlehem isn't hosting one big event that happens to run twice. It's hosting two distinct traditions, one nearly four decades old and rooted in downtown's oldest streets, the other sixteen years young and built around the industrial skyline of the South Side, and they've landed on back-to-back weekends almost by coincidence. If you've already sorted out which festival is which, you're ahead of most first-time attendees who show up at PNC Plaza looking for bagpipes, or wander Main Street hunting for a biergarten.
Bethlehem residents who've lived through enough of these autumns eventually stop checking a calendar and just know: kilts mean downtown, lederhosen mean the South Side. If you're still building that internal map, or you're new enough to the city that even the Historic Downtown and South Side distinction is fresh information, that's exactly the kind of local knowledge that makes a neighborhood start to feel like home rather than a place you're still figuring out.
If you're weighing a move to Bethlehem and want the version of this city that goes beyond festival weekends, the team at Daniel Witt Real Estate Group can walk you through what daily life actually looks like on both sides of town, and help you figure out which side fits the way you actually want to live.
