New Hampshire's fall calendar is dense. Between September 1 and November 30, 2026, the state hosts 36 fairs and festivals, producing 80 same-weekend clashes between them, pairs of events that share at least one day. That is the real planning problem for fall in New Hampshire, not finding something to do, but choosing between two or three options that only run once.
This guide breaks the season down by month and by weekend, so you can see which dates force a choice, which towns host more than one event in the same stretch, and where two same-weekend festivals sit far enough apart that reaching both in one day is not realistic.
How the season clusters by month
September carries the heaviest load, with 18 events. October follows close behind with 17. November has one, Gift of Lights in Loudon, which opens near the end of the month and runs into January of the following year. Fall in New Hampshire is really two back-to-back peak months, not a slow build toward Halloween.
Labor Day weekend: four events, two ends of the state
The season opens with a cluster. Lancaster Fair in Lancaster, Coos County, at the northern tip of the state, runs September 3 to 7, the same run of days as Hopkinton State Fair in Contoocook. Inside that same window, Gunstock Labor Day Weekend Craft Fair in Gilford runs September 5 and 6, and Cirque du Hampton Beach on the Rockingham County seacoast runs September 5. Lancaster and Hampton sit close to opposite ends of New Hampshire, so this is not a weekend where a single day trip covers the state. Pick a region and stay in it.
September 11-13: three fairs plus a Pride event
The next clash runs September 11 to 13. Mud Bowl Championship of Mud Football in North Conway, Hillsborough County Agricultural Fair in New Boston, and Hampton Beach Seafood Festival in Hampton all overlap, and Londonderry Pride lands on September 12, inside the same stretch. Hillsborough County Agricultural Fair publishes a $10 adult admission; the other three in this cluster do not have a published price in our data.
September 17-20: the biggest pileup of the fall
This is the densest weekend of the season. Granite State Fair in Rochester runs a first weekend from September 17 to 20, then returns for a second run September 24 to 27. Inside that first window, New Hampshire Highland Games & Festival runs in Lincoln, Glendi Greek Festival runs in Manchester, Hollis Old Home Days runs in Hollis, Falling Leaves Craft Fair runs in Tilton, Hampton Beach Annual Fire Show runs in Hampton, Hampton Falls Craft Festival runs in Hampton Falls, and Keene Pride closes the weekend in Keene on September 20. That is eight separate events sharing four days, spread from the White Mountains to Manchester to the seacoast to the Monadnock region. No single itinerary reaches all of them.
October 1-4: six events open the month at once
October opens with the fall season's widest single cluster. Deerfield Fair in Deerfield runs October 1 to 4. Inside that window, Mt. Washington Valley Fall Craft Fair in North Conway runs October 2 to 4, New Hampshire Book Festival in Concord runs October 2 to 3, Autumn Craft Festival on the Lake in Meredith runs October 3 to 4, and both Powder Keg Beer & Chili Festival in Exeter and Apple Harvest Day in Dover run October 3 only. All six overlap each other on at least one shared day, and they span the state from North Conway in the White Mountains to Concord in the Merrimack Valley to Exeter and Dover on the seacoast. Powder Keg carries a published $55 adult ticket, the highest price in our fall data; Mt. Washington Valley Fall Craft Fair and Apple Harvest Day are free; the other three have not published a price.
A second cluster follows a week later. Warner Fall Foliage Festival in Warner, October 9 to 11, overlaps both Milford Pumpkin Festival in Milford, also October 9 to 11, and Sandwich Fair in Center Sandwich, October 10 to 12. Milford Pumpkin Festival is free; Warner Fall Foliage Festival and Sandwich Fair have not published a price.
October 17: four corners of the state, one date
October 17 is the single busiest calendar date in the fall dataset once geography is factored in. New Hampshire Film Festival runs in Portsmouth on the seacoast (part of a longer October 15-18 run), Riverfire runs the same day in Berlin, Coos County, at the state's northern edge, Leaf Peeper's Craft Fair opens the same day in North Conway in the White Mountains, and Keene Pumpkin Festival runs the same day in Keene in the southwestern Monadnock region. Four different corners of New Hampshire, one date. Leaf Peeper's Craft Fair and Keene Pumpkin Festival are both free; admission for New Hampshire Film Festival and Riverfire is not published in our data.
Towns that host more than one fall event
A few towns show up more than once in the September-to-November window on their own. North Conway hosts three: Mud Bowl, Mt. Washington Valley Fall Craft Fair, and Leaf Peeper's Craft Fair. Hampton also hosts three: Cirque du Hampton Beach, Hampton Beach Seafood Festival, and Hampton Beach Annual Fire Show. Tilton hosts two, Falling Leaves Craft Fair and Holiday Craft Fair. Keene hosts two, Keene Pride and Keene Pumpkin Festival. Portsmouth hosts two, New Hampshire Film Festival and Portsmouth Halloween Parade. If you are building a fall trip around one of these towns, check the exact dates before assuming there is only one event to plan for.
Late October into the season's edge
Three pumpkin-themed festivals run across October: Milford Pumpkin Festival, October 9 to 11, Keene Pumpkin Festival on October 17, and Laconia Pumpkin Festival, October 23 to 24. Return of the Pumpkin People in Jackson runs as a self-guided display that our data lists across the month, though the organizers had not published confirmed start and end dates at the time of research. Portsmouth Halloween Parade and Holiday Craft Fair in Tilton both land on October 31, closing out the month. After that the calendar goes quiet until Gift of Lights opens in Loudon in late November.
Free versus not, across the fall season
Of the 36 fall events in this dataset, 18 are free to enter and 18 either charge admission or have not published a price. Do not assume; check the individual listing before you drive. New Hampshire Book Festival in Concord and New Hampshire Film Festival in Portsmouth, both within the first three weeks of October, are two examples where admission is not published in our data and should be confirmed directly with the organizer.
