Yes, if you want an empty coast and don't need Cadillac Mountain. Acadia is open in December, but from December 1 most of the Park Loop Road, including the Cadillac summit road, is closed to cars, every campground is shut, and the sun sets before 4 p.m. If this is your one trip to Acadia, come in September or October instead. My Acadia National Park guide covers the whole park for when you do.

Should You Go in December?

December suits people who like cold, wind, and having a famous shoreline nearly to themselves. Birders do well too, because the sea ducks are in. It doesn't suit a first-timer who wants Cadillac at sunrise, the full loop drive, or a campsite.

November still has the loop, which is listed open until December 1. January is colder, and my read is that it's the better bet if skiing is the point. December sits between them: you may get snow, bare ice, or rain. For the whole season, see my Acadia in winter guide.

Weather and Daylight in December

Bar Harbor averages a high of 38°F and a low of 22°F in December, against 49°F and 34°F in November and 33°F and 15°F in January (NOAA data for 2004 to 2013, via Current Results). The park describes winter as variable, from 14°F to 35°F, and warns that the peaks can be drastically different from town (NPS weather).

Daylight is the bigger constraint. Near Bar Harbor, the sun rises about 6:48 a.m. and sets about 3:54 p.m. on December 1, and it's about 7:08 and 4:02 on December 31 (approximate). Plan your day to end by 3:30.

What's Open and Closed in December

• Park Loop Road and Cadillac: closed to vehicles December 1 to April 14, weather permitting. Two sections are listed as staying open: Ocean Drive, one way from Schooner Head Road to Otter Cliff Road, and Jordan Pond Road to the Jordan Pond lot (Visiting in Winter). The park's Park Loop Road page mentions only the Ocean Drive stretch, so confirm Jordan Pond Road before you build a day around it.
• Plowing: park roads are plowed and sanded only in daylight. State and county roads are plowed all winter.
• Schoodic: the Schoodic Loop Road is listed as year-round. Schoodic Mountain Road, up to Schoodic Head, has been closed for repairs since August 31, as of November 2026 (alerts).
• Visitor centers and food: Hulls Cove Visitor Center and the park concessions, Jordan Pond House included, are closed for the season (hours and seasons). Bring lunch.
• Camping: none. Winter camping, backcountry camping, and overnight parking are all prohibited.
• Restrooms and buses: seven restrooms stay open, including Sand Beach and Jordan Pond. The Island Explorer isn't running, so you need a car.

What to Book, and When

You don't need a park reservation: Cadillac's vehicle reservations ended October 25 (fees). You do need an entrance pass, year-round: $35 per vehicle or $20 per person on foot or bike, good for seven days, plus $100 for non-U.S. residents 16 and older without an annual pass. The park doesn't take cash. Buy at the Schooner Head Road fee station, at the 24-hour card machines at Hulls Cove or the Schoodic Institute gatehouse, or online.

Book your room first. Many Bar Harbor hotels stay open at off-season rates (Visit Maine), but call ahead on restaurants. A cancellable booking is worth having, since one storm can end the plan. If you're planning a warmer return, May 2027 dates at Blackwoods should open December 1, and my Blackwoods Campground post covers how to get a site.

Where to Go When Most of the Loop Is Closed

Ocean Drive. This is the December trip: Sand Beach, Thunder Hole, and Otter Cliff. Walk Ocean Path from Sand Beach to Thunder Hole, about 0.7 mile each way. The south end, from across the Otter Point parking lot, has been closed for repairs since August 31, so check whether it has reopened. Stay well back in heavy seas; the park says water rescues here aren't uncommon.

The carriage roads. All 45 miles are open for walking, snowshoeing, and skiing. Volunteers groom when new snow tops six inches and the roadbed is frozen. Last winter they met on December 9 and were grooming by late December, so treat early December skiing as unlikely (Ski Acadia). Walk beside any ski tracks, not in them.

Ship Harbor. The park names it, along with Ocean Path and the carriage roads, as a lower-risk winter walk. I'd stick to that list.

Schoodic. Plan a half day; it's about an hour and ten minutes from Hulls Cove, and it's my pick for surf and winter birds.

Wildlife in December

The park names Schoodic Point for harlequin ducks in winter, and Frazer Point for surf scoters, long-tailed ducks, common loons, and red-breasted mergansers (Birding Schoodic). My harlequin duck post has the details. Harbor and gray seals turn up on ledges and just offshore, and white-tailed deer are most likely at dawn or dusk around Sieur de Monts and the carriage roads (mammals). None of this is guaranteed.

Bring binoculars, keep your distance, and never feed anything. Disturbing a seal is a federal crime (marine wildlife).

Holidays, Events, and Crowds

There are no NPS fee-free days in December 2026 (the last of the year is November 11). Christmas Day and New Year's Day both fall on a Friday, so I'd expect those long weekends to be the month's busiest, which still isn't very busy. Last year Bar Harbor held its tree lighting and Village Holiday Sale on the first Friday of the month (Bar Harbor Story). I haven't seen 2026 dates, so check with the town.

Safety and What to Pack

• Traction: the park calls microspikes or cleats essential on snow and ice, and warns they can be dangerous on bare, slick granite. Trekking poles are strongly recommended.
• A headlamp and a paper map. Don't count on your phone for either.
• Warm layers, a windproof shell, a hat, lunch, and water.
• Dogs stay on a 6-foot leash, and skijoring isn't allowed.

How Many Days Do You Need in Acadia in December?

One day covers Ocean Drive, Ocean Path, and a Jordan Pond walk.

Two days add Schoodic.

Three days are for skiers with real snow on the ground, or for building in a storm day.

My Acadia National Park guide has nine one- to three-day itineraries. They're built for the open season, so use the walks and the backup plans in December, and save the rest for your return. My Acadia itinerary post has a sample strenuous two-day plan for that trip.

A Simple One-Day Plan for December

1. 8:30 a.m. Take Schooner Head Road to the fee station, then drive Ocean Drive.
2. 9:00 a.m. Walk Ocean Path from Sand Beach to Thunder Hole and back.
3. 11:00 a.m. Leave by Otter Cliff Road. Eat in town or from your cooler.
4. 12:30 p.m. Drive to Seal Harbor and up Jordan Pond Road. Walk a carriage road or the east shore of the pond, in spikes if it's icy.
5. 3:00 p.m. Head out, so you're on state roads before dark. Sunset comes before 4.

Before You Go

Check the alerts the morning you go, because one storm can change which gates are open. For a warmer trip, my Acadia guide has the rest of the park day by day.

Before you go: see Acadia National Park alerts and current conditions, checked daily, for current closures and what they mean for your trip.
