6 Things That Shut Down in a Maine Town the Week the Season Ends
Bar Harbor still looks like a summer postcard the week after Columbus Day.
The schedule behind it doesn’t.
Acadia National Park’s free Island Explorer shuttles run their main routes through October 12, 2026, then park for good during the winter.
These are the things that shut down in a Maine town the week the season ends.
1. Seawall Campground’s Closing
Seawall Campground, Acadia National Park’s smaller campground near Southwest Harbor on the less-visited side of Mount Desert Island, closes for the year on October 12, at 10 a.m.
That’s Columbus Day morning.
Campers who booked the final night have to be packed up and rolling out before a ranger locks the gate behind them.
No late checkout.
The sites sit empty until the following May.
So does the harbor around it, once the last car pulls out.
2. The Island Explorer’s Season End
The Island Explorer, Acadia National Park’s free shuttle bus system, runs its main routes from June 23 until Columbus Day, then parks for the season.
No more free rides between Bar Harbor’s Village Green and the carriage roads.
Visitors who leave the car at the hotel and hop the bus into the park all summer suddenly need a vehicle again, along with somewhere to park it.
That’s the trade.
The Loop Road carries fewer buses and more cars competing for the same handful of spots at Sand Beach and Jordan Pond.
3. The CAT Ferry’s Last Crossing
The CAT (Bay Ferries’ name for its high-speed catamaran) runs between Bar Harbor and Yarmouth, Nova Scotia.
It makes its final sailing of the season on October 14, 2026, two days after Columbus Day.
That’s it until spring.
The Bar Harbor terminal sits empty for months, the same dock where cars and foot passengers boarded a three-and-a-half-hour crossing to Nova Scotia all summer.
Anyone hoping to drive onto a boat and roll off in Canada has to wait for a new season and a new schedule.
4. Sea Princess Cruises’ Last Run
Sea Princess Cruises runs its Seals, Fjord & More Cruise out of Northeast Harbor, threading Somes Sound past Bear Island Lighthouse and a colony of harbor seals.
The nearly three-hour trip stops for 45 minutes on Little Cranberry Island, a former lobster fishing village passengers can only reach by boat.
The 2026 season runs May 16 through October 15.
That’s after Columbus Day.
After October 15, the dock at Northeast Harbor sits empty until the following spring.
5. Lulu Lobster Boat Ride’s Final Trips
Lulu Lobster Boat Ride runs its two-hour sightseeing trips out of Bar Harbor’s Harborside Hotel & Marina.
A captain hauls a working lobster trap aboard so passengers can see it up close.
Along the way, passengers watch for seals, bald eagles, and the Egg Rock Lighthouse at the mouth of Frenchman Bay.
The boat’s 2026 season runs May 7 through October 17, the Saturday after Columbus Day.
Then the dock empties.
6. Sieur de Monts Nature Center’s Closing
Sieur de Monts Nature Center is Acadia National Park’s exhibit hall on the science behind the scenery, sitting just off the Park Loop Road.
The center closes for the season on October 17, the same day Lulu’s last boat ties up across the island.
One more door closes.
The Wild Gardens of Acadia sit across the courtyard, home to more than 400 native plant species sorted into the same habitats found throughout the park.
Trailheads to Dorr Mountain and the Great Meadow wetland start steps from the center’s door.
Hikers can still use those trails once the center locks up, but nobody is behind the desk to hand out a passport stamp until next May.
What Hangs on a Little Longer
Trenton Bridge Lobster Pound is the roadside lobster pound and dine-in counter at the bridge onto Mount Desert Island.
It keeps its full dine-in season running through October 25, 2026, nearly two weeks after Columbus Day.
Two more weeks.
Thurston’s Lobster Pound, on the less-crowded side of the island in Bernard, follows roughly the same pattern, closing by mid-October and reopening the following Memorial Day weekend.
Not everything on the island runs on the campgrounds’ clock.
Bar Harbor’s downtown streets hang on a few days longer still.
Bar Harbor’s paid parking program charges by the hour on the busiest downtown blocks all summer.
It runs through October 30, and then every space on Cottage Street and Main Street goes free again.
Free parking is one more sign the season is finished.

Hulls Cove’s Closing
Hulls Cove Visitor Center, Acadia National Park’s main information stop just off Route 3, closes for the season on October 31.
That’s the same day the park’s only staffed visitor center shuts down for the winter, not just the buses and the campgrounds.
The last facility to go.
Anyone who wants trail maps, tide charts, or a ranger’s advice on the fall colors has to grab it before Halloween.
The park itself never closes, and its roads and trails stay open all winter for the hikers and skiers who don’t mind an empty park with nobody behind the desk.
9 Things Nobody Warns You About Before Moving to Maine
Maine is one of the most rural states in the country, with 61.5% of its residents living outside any city or town.
That kind of space rewrites a few rules newcomers assume hold everywhere, and some of what catches new Mainers off guard costs money before they even unpack.

In 2025, 14.15 million visitors came to Maine and spent $9.37 billion, up 1.4% from 2024.
Many of them drove home confident about a state they’d only seen for four days, and a Mainer would push back on half of it.
