Editor’s Pick · Destination Guide

Bar Harbor, Maine

Bar Harbor, Maine, on Mount Desert Island, is the main gateway to Acadia National Park. Visitors drive the Park Loop Road, bike the historic carriage roads and watch sunrise from Cadillac Mountain, which requires an advance vehicle reservation for the summit road in season (May 20 to October 25 in 2026). Fall foliage typically peaks around mid-October, and summer is the busiest season.

Official visitor information

Fog lifts off Frenchman Bay in the morning, and the pink granite of Mount Desert Island appears piece by piece: the rounded summits of Acadia, the spruce-lined shore, the lobster boats riding at their moorings in Bar Harbor. By midday the town's streets are busy with people heading for the trails, the harbor or an ice cream cone, and by evening the light over the Porcupine Islands turns everything gold.

Bar Harbor is the classic base for Acadia National Park, and it is our Editor's Pick for a coastal trip that pairs real wilderness with a lively, walkable town.

Why is Bar Harbor worth visiting?

Bar Harbor puts you minutes from Acadia National Park, with mountains rising straight out of the Atlantic, more than 150 miles of hiking trails and 45 miles of historic carriage roads. Few places on the East Coast combine ocean and mountain scenery so closely.

The town itself has a long history as a summer resort, with grand cottages, a waterfront park and the Shore Path tracing the rocky coastline past historic homes.

When is the best time to visit Bar Harbor?

Summer and fall are peak seasons, with fall foliage typically peaking around mid-October. Spring is quiet and cool, and winter is a peaceful time when many businesses close.

  • Spring: Trails and roads gradually open as the season begins, and crowds stay light. Some park roads and businesses open later in spring.
  • Summer: Warm days, whale watching, sea kayaking and the full menu of lobster shacks and harbor cruises. It is the busiest time, so plan reservations ahead.
  • Fall: Crisp air and color across the mountains. Foliage on Mount Desert Island typically peaks around mid-October, though timing varies with the weather.
  • Winter: Snowy carriage roads for cross-country skiing and snowshoeing, quiet streets and dramatic winter seas. Many shops and restaurants are closed.

Do you need a reservation to drive up Cadillac Mountain?

Yes, during the main season. In 2026, Acadia requires a vehicle reservation for Cadillac Summit Road from May 20 through October 25, sold in advance through Recreation.gov and not at the park.

Reservations are offered for sunrise and daytime windows, and a park entrance pass is required separately. A portion of reservations is released well ahead and the rest closer to the date, so check the National Park Service website for the current schedule. Visitors who hike or bike to the summit do not need a vehicle reservation.

What are the top things to do in Bar Harbor and Acadia?

Park Loop Road

This scenic road links Sand Beach, Thunder Hole, Otter Cliff and Jordan Pond. Stop often, walk the Ocean Path along the cliffs, and time your visit to Thunder Hole near high tide.

Carriage roads

Built by John D. Rockefeller Jr., Acadia's broken-stone carriage roads and their handsome stone bridges are perfect for biking and walking, and they are closed to cars.

Jordan Pond

A clear glacial lake framed by the twin mountains known as the Bubbles. Walk the shoreline trail, then enjoy tea and popovers, a long tradition at the Jordan Pond House restaurant.

Bar Island and the Shore Path

At low tide, a gravel bar emerges and you can walk from town to Bar Island. Watch the tide tables carefully so you do not get stranded. In town, the Shore Path offers easy ocean views.

Where should you eat and stay in Bar Harbor?

Seafood rules: lobster rolls, steamed lobster, chowder and fresh-caught fish, plus wild blueberry desserts. The downtown streets around the Village Green have bakeries, pubs and harborfront dining.

Lodging ranges from historic inns and bed-and-breakfasts to hotels, motels, cottages and campgrounds, including campgrounds inside the park. Summer and foliage season fill up early.

How do you get to Bar Harbor?

Bar Harbor is on Mount Desert Island, connected to the mainland by bridge near Trenton. Hancock County-Bar Harbor Airport is the closest airport, and Bangor International Airport is a little over an hour's drive away. In season, the fare-free Island Explorer shuttle buses connect town with many park destinations, which helps with parking.
