Marshall County Indiana Marshall County Blueberry Festival
Labor Day weekend in Plymouth belongs to blueberries. For four days, from Friday through Monday, Centennial Park hosts the Marshall County Blueberry Festival, the event catalogued under this sheet title and often shortened in local usage to the Blueberry Festival. Plymouth is the seat of Marshall County, and once a year the county seat’s park fills with a carnival, craft and food vendors, stage entertainment, sporting contests and a Monday parade that regional news coverage describes as drawing nearly twenty thousand spectators onto the streets. The festival is organised by Marshall County Blueberry Festival, Inc., the incorporated body named on the organiser’s own vendor documents, and a city-guide layer describes admission as free. Regional news and tourism layers bill the twenty twenty-six edition, running from Friday the fourth of September to Monday the seventh of September, as the festival’s sixtieth year. What began in nineteen sixty-six as a Labor Day celebration tied to a state anniversary has become the county’s signature long weekend, built around a crop that once made Marshall County responsible for one third of all the blueberries grown in Indiana.

About the Marshall County Blueberry Festival
The Marshall County Blueberry Festival is an annual four-day festival held over Labor Day weekend in Centennial Park in Plymouth, Indiana. Every layer read gives the event the same published name, Marshall County Blueberry Festival, with Blueberry Festival as the shortened local form. The organiser’s own vendor application for the twenty twenty-six edition prints the running body’s name as Marshall County Blueberry Festival, Inc. That document draws a clear line between the present-day festival organisation and the Plymouth Jaycees, the civic group that organised the original celebration in nineteen sixty-six; the two bodies belong to different chapters of the story and are not the same organisation wearing a new name. An events platform records the organiser’s stated objectives as providing family activities at little or no cost, and a city-guide layer calls the gathering a free-admission event, so the festival’s centre of gravity is an open park rather than a gated ground. A listing layer bills the twenty twenty-five edition as the fifty-ninth annual, while regional news and tourism layers describe the twenty twenty-six edition as the sixtieth year. The festival also has a mascot: the tourism layer names him as Hank the Blueberry, designed by Ed Miller, a longtime art teacher at Argos High School, a detail that ties the event to a classroom elsewhere in the county as well as to the county seat. The surviving record is unusually complete for an event of this size, resting on the organiser’s own vendor documents, a county tourism layer, an events platform and regional news coverage, each describing the same festival, in the same park, on the same holiday weekend.

History
The tourism layer and the events platform tell the founding story the same way. The festival began in nineteen sixty-six, when the Plymouth Jaycees organised a Labor Day celebration for Marshall County to observe Indiana’s sesquicentennial, the state’s one hundred fiftieth anniversary. A celebration needed a theme, and the county’s fields supplied one: at that time Marshall County provided one third of Indiana’s blueberry crop, which made the blueberry a fitting emblem for a county-wide party. The year nineteen sixty-six is the layers’ own statement, and it is worth keeping separate from the anniversary billings that accumulate around any long-running event. When regional news and tourism layers call twenty twenty-six the sixtieth year, and a listing layer calls twenty twenty-five the fifty-ninth annual, those billings describe how the editions are counted and marketed; the founding itself rests on the nineteen sixty-six account, not on arithmetic worked backwards from a round number. Over the decades the running of the festival passed from the Jaycees’ original celebration to a dedicated organisation, and the name printed on the twenty twenty-six vendor application, Marshall County Blueberry Festival, Inc., shows the incorporated form that body eventually took. The tourism layer adds that the festival has been named a Top 100 Event in North America three times, a claim that belongs to that layer but which underlines how far a sesquicentennial picnic idea travelled.
What to Expect
Four days in Centennial Park hold a great deal. A carnival anchors the grounds, surrounded by craft, commercial and food vendors; the tourism layer counts more than one hundred food options alone. Entertainment runs on three stages, and sporting events are spread across all four days, so the programme never narrows to a single headline act. Runners get the Blueberry Stomp, with five-kilometre and fifteen-kilometre courses, while a bicycle cruise offers a slower way to take part. Hot air balloons launch from the grounds and return after dark for a balloon glow. Wheels feature heavily: the Hoosier Old Wheels Antique Car Show displays older machinery, and a twenty twenty-six news layer adds motorcycle and classic-car shows alongside tractor pulls. The same news layer lists a beer garden, a drone show and fireworks among the twenty twenty-six attractions. Everything builds toward Monday morning, when the Labor Day parade steps off at nine thirty. Regional news coverage puts the parade at more than one hundred units and says that, traditionally, nearly twenty thousand spectators line the streets to watch it pass, figures that belong to that layer but which convey the scale of the festival’s closing act.
Planning Your Visit
The shape of the weekend comes first. The festival runs four days, Friday through Monday over Labor Day weekend; in twenty twenty-six those dates are Friday the fourth of September to Monday the seventh of September. A regional news layer prints the hours as nine in the morning to nine in the evening on Friday, Saturday and Sunday, shortening to nine in the morning until six in the evening on Monday, so the final day rewards an early start. Admission itself is free: a city-guide layer describes the event as free-admission, and the organiser’s stated objectives, carried on an events platform, are family activities at little or no cost. The one charge a visitor should plan around is parking. Official parking sits at Plymouth High School and is charged per car; a listing layer gives ten dollars per car, or twenty dollars for a weekend pass, figures fenced to that listing and its year rather than a permanent tariff. Anyone coming mainly for the parade should be in place well before nine thirty on Monday, since regional news describes crowds of nearly twenty thousand along the route. Beyond that, the practical advice is pacing: with more than one hundred food options, three stages and events scattered across four days, spreading choices over the weekend beats trying to compress everything into a single afternoon.

A Sample Itinerary
The first day rewards a slow start. Arrive when the park day begins at nine, walk the vendor rows while the grounds are still fresh, and use the first day to learn the layout of Centennial Park, noting where the three stages and the carnival sit in relation to each other. Saturday can carry the active programme: the Blueberry Stomp runs, the bicycle cruise and the sporting events spread across the weekend all reward a full day, and the antique cars of the Hoosier Old Wheels show deserve unhurried attention. Sunday lends itself to the spectacle end of the programme, with balloon launches, the glow after dark and the evening attractions the twenty twenty-six news layer lists, such as the drone show and fireworks, on the nights they are staged. Monday belongs to the parade. Take up a place along the route before the nine thirty step-off, watch more than one hundred units pass, then spend the shorter final afternoon, which ends at six, revisiting favourite food vendors for a last taste of blueberry cooking before the park empties and the long weekend closes.
How It Compares
Blueberry festivals are a North American habit, and generic festival-directory pages list celebrations of the same fruit in several other states, each tied to its own growing country. This one is distinguished by its setting and its origin: it fills the county seat’s Centennial Park in Plymouth, Indiana, and it grew out of a nineteen sixty-six celebration mounted when Marshall County grew one third of its state’s blueberry crop. It should also not be confused with the Marshall County fair, a separate event in the county’s calendar, or with the smaller Plymouth happenings that surface in regional roundups, such as museum lectures and car cruze-ins. Those are their own occasions. The Blueberry Festival is the Labor Day weekend event, four days long, organised by its own incorporated body, and measured by its organisers against a family-at-little-cost standard rather than against fairground gate receipts.

Checklist
- Confirm the year’s Friday-to-Monday dates, which move with Labor Day weekend
- Remember that Monday runs shorter hours, nine to six, and holds the parade
- Be in place before the parade steps off at nine thirty on Monday morning
- Budget for per-car parking at Plymouth High School even though admission is free
- Spread the food vendors across several days rather than attempting them all at once
- Watch for Hank the Blueberry, the festival mascot, around the grounds
- Check the organiser’s documents and current listings for the year’s programme details
Beyond the Festival
Plymouth carries its county-seat role quietly the rest of the year, and the festival is best understood as the town opening its central park to the whole county for one long weekend. Centennial Park is the anchor: everything documented about the event happens in or around it, from the carnival to the balloon launches. The festival’s connections reach beyond the town limits in small ways. Its mascot was designed by a longtime art teacher from Argos High School, and its founding story belongs to the county’s farmland as much as to the town, since the blueberry crop that named the festival was a county-wide harvest. A visitor with time around the weekend will find the roundups that mention the festival also mention quieter Plymouth events across the year, but the documented record keeps the spotlight where it belongs, on four days in the park at the end of summer.
Why It Matters
The festival matters to Marshall County because it converts an agricultural fact into a shared ritual. A crop that once supplied one third of Indiana’s blueberries gave the county a name for its party, and the party outlived the anniversary that prompted it: the sesquicentennial passed in nineteen sixty-six, yet the celebration returned every Labor Day weekend after. The organiser’s stated aim of family activities at little or no cost, together with free admission, keeps the event open to the whole county rather than to ticket holders only. Regional news treats the Monday parade as a fixture worth counting in tens of thousands of spectators, and the tourism layer’s claim of three Top 100 Event honours in North America suggests the wider events world has noticed too. Sixty years of billings point the same way: this is the county’s signature weekend.

Frequently Asked Questions
Is admission to the grounds really free of charge?
Yes, on the documented record. A city-guide layer describes the festival as a free-admission event, and the organiser’s stated objectives, carried by an events platform, speak of family activities at little or no cost. Free admission does not mean a free car park: official parking at Plymouth High School is charged per car, and a listing layer prices it at ten dollars per car or twenty dollars for a weekend pass for the edition it covers.
Who runs the festival today, and is it the same body that started it?
The twenty twenty-six vendor application prints the organiser’s name as Marshall County Blueberry Festival, Inc. That is not the body that started the event. The organiser’s own document distinguishes the festival organisation from the Plymouth Jaycees, who organised the original nineteen sixty-six celebration; the incorporated festival body is the later, dedicated successor to that first civic effort.
What is the Blueberry Stomp?
The Blueberry Stomp is the festival’s running event, documented with two distances: a five-kilometre run and a fifteen-kilometre run. It sits within a programme that also includes a bicycle cruise and sporting events spread across all four days of the weekend.
Who is Hank the Blueberry?
Hank the Blueberry is the festival’s mascot. The tourism layer credits his design to Ed Miller, a longtime art teacher at Argos High School, which gives the character a Marshall County classroom in his family tree rather than a marketing office.
What to Expect From the Next Marshall County Indiana Marshall County Blueberry Festival
How often is Marshall County Indiana Marshall County Blueberry Festival held?
The festival returns every year over Labor Day weekend, occupying four days from Friday through Monday. Its rhythm is tied to the holiday weekend rather than to fixed calendar dates, so the pattern is annual even though the numbered days move.
When is the next Marshall County Indiana Marshall County Blueberry Festival?
The documented edition runs from Friday the fourth of September to Monday the seventh of September in twenty twenty-six. Following the established pattern, the next edition after any given year falls on the following Labor Day weekend, Friday through Monday, with exact dates and hours confirmed in the organiser’s documents and listings as that weekend approaches.
Will the dates change?
The calendar dates change every year by design, because the festival is anchored to Labor Day weekend instead of to a fixed day of the month. What stays constant is the shape: four days, Friday to Monday, in Centennial Park. Hours printed for twenty twenty-six came from a regional news layer, and future hours rest with the organiser’s own publications.
Closing
From a Jaycees celebration for a state anniversary to an incorporated organisation’s four-day weekend drawing county-wide crowds, the Marshall County Blueberry Festival has kept its original logic intact: take the crop the county was known for, open the county seat’s park, and charge families little or nothing to join in. Labor Day weekend in Plymouth still runs on that recipe.
