10 Things Happening In Maine This September That Deserve A Spot On Your Calendar

Oh, September in Maine, you absolute charmer. While summer starts winding down, the Pine Tree State hits its stride with crisp mornings, early hints of fall color, and a calendar bursting with things to do.

Picture cool sunrises that melt into warm afternoons perfect for wandering coastal towns or hiking deep into the woods. I have circled the dates that look especially tempting, and this month is packed with reasons to get out of the house.

Expect harvest festivals, maritime celebrations, tasty local flavors, and outdoor fun that stretches from the rocky shore all the way inland. You can climb a historic lighthouse, cheer on a community race, or spend an afternoon sampling Maine-made treats.

September may sit between two seasons, but it refuses to feel like an in-between month. Grab your calendar because these ten events deserve a spot on it.

1. Camden Windjammer Festival, Camden

Sails everywhere you look, that is the first thing that greets you when the Camden Windjammer Festival rolls into Camden Public Landing in Camden, Maine, on September 4-5, 2026. The tall ships glide into the harbor between 2 PM and 4 PM on Friday in a parade that draws every camera on the dock.

Beyond the fleet, you get live music, maritime demonstrations, and a marketplace stuffed with local crafters and food vendors. Kids love the Captain Kid’s Corner, and everyone laughs through the splashy Lobster Crate Race, a beloved coastal tradition.

You can even tour the schooners during open house visits, peeking into life aboard these historic beauties. Friday runs 10 AM to 5 PM with evening music, while Saturday opens at 9 AM with a pancake breakfast and a 5K road race to shake off sleepy legs.

Admission is free, though a few activities may ask you to sign up ahead of time. If you want a first taste of Maine’s Midcoast charm, this Labor Day weekend celebration sets a high bar for the rest of the month.

2. Eastport Salmon & Seafood Festival, Eastport

Down in the easternmost city in the country, the 38th annual Eastport Salmon & Seafood Festival takes over the waterfront from September 4-6, 2026, spilling across Overlook Park and the Sutherland Amphitheater in Eastport, Maine.

The whole weekend tips its hat to the region’s fishing and aquaculture roots.

Saturday invites you to poke around historic home tours, while Sunday centers on a fresh grilled salmon dinner. Buy a salmon dinner ticket and you can get a discounted boat tour of the salmon pens in Passamaquoddy Bay, offering a neat behind-the-scenes look at local aquaculture.

Entertainment keeps rolling with free youth fishing derbies, art activities for all ages, and a moonlight screening of a famous shark movie under the stars. Wander among craft vendors, galleries, and gift shops while regional musicians play nearby.

Hungry hands can grab crab rolls, blueberry cake, and Maine farm-fresh oysters, or join an oyster shucking workshop for a hands-on treat. If you crave small-town warmth mixed with big flavors, this seaside gathering is a delicious reason to drive way east.

3. Blue Hill Fair, Blue Hill

Step right up for a genuine slice of Americana at the Blue Hill Fair, running September 3-7, 2026 at the Blue Hill Fairgrounds, 233 Ellsworth Road, in Blue Hill, Maine. This down-to-earth country fair lands over Labor Day weekend and sits a short hop from Acadia National Park.

The fairgrounds buzz with livestock events, spinning carnival rides on the midway, and demonstrations that show off rural know-how. Thursday brings Dollar Day, with $1 admission and $1 mechanical rides, while Friday offers reduced admission for folks 62 and older.

Entertainment stacks up fast, including the high-energy Ready Go Dog Show and the roaring Wheels and Steel Stunt Show. Country singer Darryl Worley performs Saturday, a Bon Jovi tribute plays Sunday, and Saturday night lights up with fireworks marking America’s 250th birthday.

Do not skip the State of Maine Championship Demolition Derby on Monday, always a crowd favorite. Best of all, children 11 and under get in free every single day, making this a wallet-friendly family outing packed with old-fashioned fun.

4. Trails End Festival, Millinocket

Adventure is in the air when the Trails End Festival sets up in Veterans Memorial Park in downtown Millinocket, Maine, from September 11-13, 2026. This three-day party celebrates the Katahdin region and its fame as the northern finish line of the Appalachian Trail.

Expect free live music that keeps toes tapping, plus a lineup of local vendors and food trucks serving up hearty bites. Families get their own slice of the fun with games and activities built for all ages, so nobody stands around bored.

The festival captures the friendly small-town feel of Millinocket while shining a light on hiking, trail running, and mountain biking. Look for woodsmen demonstrations, a climbing wall, and family activities that celebrate the outdoor spirit of the Katahdin region.

Do not miss the popular Rubber Duck Race, a playful splash of competition that always draws cheers. Whether you are a serious hiker or just love a good outdoor gathering, this is the weekend where trails end and the celebration truly begins in the shadow of Mount Katahdin.

5. Maine Open Lighthouse Day, Cape Elizabeth

Turn your eyes toward the coast because Maine Open Lighthouse Day flings open its doors on September 12, 2026, welcoming visitors to over a dozen historic lights across the state of Maine. My top pick is the postcard-famous Portland Head Light in Cape Elizabeth, tucked inside Fort Williams Park.

The day gives you one of only two yearly chances to climb the 85 steps of Portland Head Light’s tower. At the top, sweeping views of Casco Bay and the park below reward every huffing, puffing step.

It is a rare chance to get up close with these coastal guardians, and many locations also open keeper’s houses and small museums. The event is sponsored by the U.S. Coast Guard, the Maine Office of Tourism, and the American Lighthouse Foundation.

Plan ahead if you want to climb, since tickets are limited and handed out starting at 8:45 AM to people already in line. There is also a 48-inch height rule for tower climbers.

Arrive early, bring your camera, and enjoy a truly illuminating slice of Maine history.

6. Laudholm Nature Crafts Festival, Wells

Artsy souls, this one is calling your name. The 38th annual Laudholm Nature Crafts Festival runs September 12-13, 2026, daily from 10 AM to 4 PM, at the scenic Wells Reserve at Laudholm in Wells, Maine.

The historic property turns into a sprawling outdoor gallery for the weekend.

More than 150 juried New England artisans set up shop, showing off fine art, handcrafted jewelry, ceramics, fiber crafts, and clever mixed media pieces. Strolling the seaside grounds while browsing feels like a treasure hunt with a view.

Live music drifts through the air, and local food vendors keep you fueled between booths. On Sunday, a special Native Plant Sale lets you carry a little greenery home along with your finds.

This festival is more than shopping, since it doubles as a key fundraiser for Laudholm Trust, supporting science, education, and conservation at the Wells National Estuarine Research Reserve. Buy tickets online ahead of time or at the gate.

For a laid-back fall day mixing creativity, coastal scenery, and a good cause, few outings feel this rewarding.

7. Maine Cheese Festival, Pittsfield

Cheese lovers, clear a spot on your plate. The 10th annual Maine Cheese Festival rolls out on September 13, 2026, at Manson Park in Pittsfield, Maine.

This tasty day celebrates the state’s booming food, beverage, and artisan community.

With more than 65 Maine-made vendors gathered in one spot, you can sample a dizzying spread of cheeses, plenty of them crafted by makers who genuinely know their cows by name. Every nibble tells a story about local farms and careful craftsmanship.

Beyond the samples, the festival serves up demonstrations, live music, and educational moments that deepen your appreciation for handmade food. Families are welcome, with kids’ activities keeping younger visitors happily busy.

Want to start the fun early? On September 12, a special film and cheese event features a screening of Holy Cow at the Maine Film Center in Waterville, paired with a Maine cheese event at Main Street Provisions.

If you believe a great day should smell faintly of aged cheddar, this festival delivers a full afternoon of flavor and friendly faces you will happily remember.

8. Camden International Film Festival, Camden and Rockland

Movie buffs, your kind of magic arrives with the 22nd annual Camden International Film Festival, playing across Midcoast venues in Camden, Rockport, and Rockland, Maine, from September 17-20, 2026.

This respected festival is known for bold documentary features and shorts pulled from all over the globe.

The Camden Opera House at 29 Elm Street serves as a principal venue, offering a grand setting for many screenings and thoughtful discussions. Plenty of these films land their U.S. premieres right here in Maine.

Alongside the movies, the Points North Forum packs in panels, talks, and masterclasses that peel back the curtain on nonfiction storytelling. It is a golden chance to rub shoulders with both rising and established filmmakers.

Getting between venues is easy thanks to a free Festival Shuttle running between Rockland and Camden, timed around screenings and evening After Dark parties. Passes are available through the Points North Institute’s website.

If you like your September itinerary sprinkled with arts and culture, this cinematic gathering brings big ideas and creative energy to Maine’s coast in the best possible way.

9. Dempsey Challenge, Lewiston

Lace up those sneakers or pump up your tires, because the Dempsey Challenge returns to Lewiston, Maine, on September 19, 2026. Founded by Maine native and actor Patrick Dempsey, this run, walk, and cycling fundraiser gathers a big-hearted crowd at Simard-Payne Memorial Park.

You get to pick your own adventure, whether that is a 5K or 10K run and walk, or a cycling route stretching from 25 to 65 miles on scenic roads. Gravel riders can tackle a roughly 58-mile route for extra crunch under their tires.

Cannot make it in person? A virtual option lets you join from anywhere on the planet.

Every dollar raised supports the Dempsey Center, which offers caring, no-cost services to people affected by serious illness and to their families.

Adult in-person participants pay a registration fee and meet a fundraising minimum, but the day includes a participant t-shirt, a Maine-inspired finisher meal, and a beverage ticket. Warm, uplifting, and full of community spirit, this event proves that moving together can make a real difference for so many.

10. Common Ground Country Fair, Unity

Save the biggest celebration for last. The 50th annual Common Ground Country Fair, hosted by the Maine Organic Farmers and Gardeners Association, runs September 25-27, 2026, at the Common Ground Education Center in Unity, Maine.

This milestone year promises an extra festive buzz.

More than 700 scheduled events fill the grounds, including workshops, live local music, and family activities like a garden parade, corn husk doll crafting, and shaking cream into butter. There is always something new around every corner.

Wander an enormous marketplace with over 600 exhibitors selling handmade goods and tools for sustainable living, then refuel with organic and locally sourced food. Special 50th anniversary touches include a t-shirt parade and a standout Exhibition Hall display.
