While Acadia is open year-round, many services and businesses operate on a seasonal schedule. The primary visitor center is open mid-April through October, while the fare-free Island Explorer shuttle bus, which allows you to go car-free, is only in operation late June through early October. Most stores and restaurants are open by mid-June. Paid vehicle reservations are now required for Cadillac Summit Road from late May through early October, learn more here: Acadia Vehicle Reservations.

If you're looking to avoid the large crowds in July and August, consider the fringe months of May/June or late September/October. Traffic can be heavy in the summer months, so you may want to spend more time exploring the western part of Mount Desert Island, known as the 'quiet side.' Some locals say the best time to visit is the second week of September when kids are back in school but before the fall foliage seekers arrive (find a foliage tracker here). We visited in mid-October, and while some trails were closed due to ice, we had many hiking trails to ourselves. No matter when you decide to visit, make sure to check the latest park conditions. 

Picturesque villages and towns are peppered around Acadia National Park on Mount Desert Island, providing a variety of lodging options. There is no lodging within park boundaries other than campsites.

Compass & Key enjoyed the charming Holland Inn bed & breakfast ($, hollandinn.com), located within easy walking distance of Bar Harbor's Main Street and the Great Meadow Loop Trail, one of several historic Village Connector Trails into Acadia. The cozy breakfast room makes it easy to meet fellow travelers, and the innkeepers are eager to recommend area sites and restaurants. The hotel offers 13 rooms and operates from late April through early November.

Glampers rejoice! Under Canvas ($$$, undercanvas.com) has expanded to Acadia for the 2021 season. While the resort is located off Mount Desert Island (35-minute drive), it provides a luxurious way to reconnect with nature among 100 acres and an expansive coastline, yet still accessible for day hikes and other adventures in Acadia.

For a historic hotel on the quiet side of Acadia, book a room at The Claremont ($-$$, theclaremonthotel.com). Located a few miles from the Long Pond and Echo Lake areas of Acadia, and about a half-hour drive from Bar Harbor, this shorefront resort has been hosting visitors every summer since 1884. Along with clay tennis courts and rowboats, the Claremont is known for their croquet courts, hosting a tournament every August. The 24 rooms in the main hotel are available starting in mid-June, while the 16 self-service cottages on the property open in late May. All rooms are available through mid-October.

Acadia is unique among national parks, bordered by historic villages with plenty of dining options to satisfy residents and visitors alike. You'll find restaurant recommendations peppered among our itineraries, but here are three favorites.

1) Trenton Bridge Lobster Pound, 1237 Bar Harbor Road, Trenton (view map)

In the gateway community of Trenton, this no-frills, traditional lobster house opened in 1956 and consistently receives rave reviews. Lobster salad is served on a sandwich instead of a roll because the owner's grandmother served it that way. Open Father's Day through Columbus Day, 8a-7:30p, Mon-Sat, closed most Sundays.

2) The Burning Tree Restaurant, 69 Otter Creek Dr, Otter Creek (view map)

Seek out the Burning Tree for exceptional seafood in a casual setting beyond Bar Harbor, and a popular destination for locals.  Open seasonally from 5pm daily except Tuesdays, when it is closed.

HOW TO GET THERE

Compass & Key recommends flying to nearby Bangor International (BGR) and renting a car for the one-hour drive to Mount Desert Island. If you'd like to explore more of the Maine coast, fly into Portland (PWM) and spend a day or two driving north to Acadia to explore the villages along the way (it's only about three hours to drive from Portland, but you'll need more time if you decide to explore). Boston is another option for flights but expect a 4hr30min drive. 

GETTING AROUND

Most visitors drive around the park. The Park Loop Road and parking areas at the carriage road entrances can be crowded during the summer months, so you may want to take the free shuttle bus, the Island Explorer, connecting many villages and trailheads throughout Mount Desert Island. Paid vehicle reservations are now required for Cadillac Summit Road from late May through early October, learn more here: Acadia Vehicle Reservations. If you're visiting off-season, start your day early or later in the afternoon for the best chances to find parking at the trailheads.

Park passes are required in Acadia National Park from May through October and can be purchased online or at the visitor centers and campgrounds. A 7-day pass is $30 per car or $15pp with no car, while an annual pass is $55. If you're planning to visit more than one National Park in a 12-month period, purchase the America the Beautiful National Parks pass for $80. Seniors have access to an $80 lifetime pass and U.S. Military personnel and dependents qualify for a free annual pass. We love supporting the parks and purchase the $80 annual pass each year.
