Winter turns Acadia into a different park. The Park Loop Road closes to cars, the campgrounds and park stores shut, and the island gets quiet. What's left is the granite coast, 45 miles of carriage roads to ski or snowshoe, and a lot of room. If you're comfortable with cold wind, short days, and a little planning, it's a good season to come.

Why Go in Winter

Solitude is the main reason. The summer lines at Sand Beach and Jordan Pond are gone, and you don't need a Cadillac vehicle reservation, because that system only runs May 20 to October 25 (fees and reservations, as of October 21, 2026).

The trade-off is convenience: you'll eat and sleep in town and see the park from two short open road sections, on foot, or on skis.

Weather and Daylight

The park's weather page describes winter as variable, with temperatures from about 14°F to 35°F. Wind off the water makes it feel colder, and the summits can be very different from Bar Harbor. Around the solstice, Bar Harbor gets just under 9 hours of daylight (sunrise-sunset.org), so plan to be off the trails by mid-afternoon. For the latest forecast, the park lists 207-667-8910 and 207-288-3338.

What's Open and What's Closed

• Park Loop Road: closed to vehicles from December 1 to April 14, weather permitting, including the road up Cadillac Mountain (visiting in winter). Two sections stay open: Ocean Drive, one way from Schooner Head Road to Otter Cliff Road, and the Jordan Pond Road from Seal Harbor to the south end of Jordan Pond. Unpaved park roads close November 15 (operating hours and seasons).
• Plowing: park roads are plowed and sanded only during daylight. State and county roads on Mount Desert Island are plowed all winter.
• Schoodic: the Schoodic Loop Road is open year-round. As of October 21, 2026, the road up Schoodic Head is closed for repairs (alerts).
• Entrance passes: required year-round, and the park is cashless. The Park Loop Road fee station at Schooner Head Road stays open all year, and card-only fee machines run 24 hours at Hulls Cove Visitor Center and the Schoodic Institute gatehouse. The Hulls Cove Visitor Center itself closes for the season on October 31.
• Camping and lodging: all park campgrounds are closed for the season, and there's no winter camping or overnight parking anywhere in the park (camping). Stay in Bar Harbor or another nearby town.
• Food and shuttles: the Jordan Pond House and the other park concessions close by early November, and the fare-free Island Explorer buses ended their 2026 service October 12 (Island Explorer). You'll need a car.
• Restrooms: seven stay open in winter, including Sand Beach, Fabbri Picnic Area, Jordan Pond, and the Eagle Lake carriage road.

The Best Things to Do in Winter

• Ski or snowshoe the carriage roads. The broad, gentle carriage roads are the park's winter highlight. When there's more than six inches of snow on a frozen roadbed, volunteers set and groom ski tracks; the park points to Friends of Acadia's Ski Acadia page for grooming reports. Walk beside the tracks, not in them. You can also ski the unplowed park roads, but those are snowmobile routes, so stay alert.
• Drive Ocean Drive. The open stretch passes Sand Beach, Thunder Hole, and Otter Cliff. Heavy winter seas are spectacular here, but the park asks you to give them space: water rescues on this coast aren't uncommon.
• Take a sensible walk. The park steers winter hikers toward Ship Harbor, Ocean Path, and the carriage roads rather than the steep summit trails. As of October 21, 2026, Ocean Path is closed for repairs from across the Otter Point parking lot to its southern end, so walk the section north of there.
• Drive Sargent Drive. It follows the shore of Somes Sound, the glacier-carved inlet.
• Try ice fishing. It's popular when the ice allows, and it needs a Maine fishing license. Check ice thickness yourself; larger lakes can have open water.

If you want the island laid out day by day, my Acadia guide covers the seasons, passes, and a bad-weather backup for every day it plans.

Wildlife in Winter

White-tailed deer are plentiful, and the park says your best chance is at dawn or dusk around Sieur de Monts and along the carriage roads (mammals). Snowshoe hares turn white in winter. Offshore, harbor and gray seals are common along Maine's coast; scan the water and the ledges with binoculars (marine wildlife). The park even mentions the chance of a snowy owl in winter, though it's candid that most visitors will never see one (owls). Nothing is guaranteed.

Keep your distance, use a zoom lens, and don't feed anything, red squirrels included (wildlife viewing). Disturbing a seal is a federal crime. For a wildlife emergency, call park dispatch at 207-288-8791 or 911.

Safety and What to Pack

The park calls microspikes, crampons, or other traction footwear essential on snow-packed and icy trails, and it strongly encourages trekking poles. It also warns that spikes can be dangerous on bare, slick granite, so watch your footing there. Expect early darkness, carry a headlamp and a paper map (cell service is spotty), and dress in warm layers against frostbite and hypothermia (safety). Be ready to turn back. Dogs must stay on a 6-foot leash, which is why dog sleds and skijoring aren't allowed.

A Simple Winter Day in Acadia

1. Before you leave Bar Harbor: check the forecast and the park's alerts, and pack traction, layers, water, and lunch.
2. Morning: take Schooner Head Road to the Park Loop Road fee station, buy or show your pass, and drive Ocean Drive. Stop at Sand Beach and Thunder Hole, and walk the open northern part of Ocean Path.
3. Midday: leave by Otter Cliff Road and eat in town or in the car; there's no food service in the park.
4. Afternoon: drive to Seal Harbor and up the Jordan Pond Road. With good snow, ski or snowshoe a stretch of carriage road. Without it, walk the carriage roads in spikes.
5. Late afternoon: take Sargent Drive along Somes Sound, and be back on main roads before dark.

Before You Go

Winter weather here changes fast. Check the park's current conditions and alerts the morning you go, and read the visiting in winter page for the snowmobile routes and road details.

When you're ready to plan a bigger trip, my guide to Acadia National Park has nine one- to three-day itineraries at easy, moderate, and strenuous effort, each with a backup plan for bad weather or closures.

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