Train from Boston to Bar Harbor, Maine | Routes That Work

Bar Harbor has no rail station; Amtrak gets you as far as Portland or Brunswick before a bus, shuttle, or car transfer.

The route people mean by train from Boston to Bar Harbor, Maine is really a rail-plus-road trip: Amtrak carries you north from Boston, but the final stretch to Mount Desert Island runs by road. The cleanest car-free plan is usually Concord Coach from Boston to Bangor, then Downeast Transportation to Bar Harbor; the train makes sense if you want a Portland stop or plan to rent a car for the coastal leg.

Boston also has a station trap. The Amtrak Downeaster leaves from Boston North Station, while many Maine-bound buses leave from South Station or Logan International Airport, so tight cross-town transfers can ruin an otherwise good plan.

Can You Take A Train To Bar Harbor?

Bar Harbor does not have passenger rail service, so no train reaches the village, Acadia National Park, or Mount Desert Island. The closest useful Amtrak stops are Portland and Brunswick on the Downeaster route.

Amtrak Downeaster schedules currently show daily northbound trains from Boston North Station to Portland in about 2 hours 35 minutes and to Brunswick in about 3 hours 20 minutes. Brunswick is the end of the rail line, not the end of the trip.

Boston To Bar Harbor By Train And Transfer: Every Route Compared

Boston to Bar Harbor works by public transport, but the route with the fewest moving parts is not the pure train route. The table below shows the realistic choices, including where the rail option fits.

Where The Transfer Gets Tricky

The hard part is not Boston to Maine; the hard part is the last 45 to 160 miles, depending on where you leave the train or bus. Bar Harbor sits on Mount Desert Island, and the road approach funnels through Ellsworth and Trenton.

The current public-bus link from Bangor is useful but narrow. Downeast Transportation’s Bar Harbor-Bangor bus runs Monday through Friday, does not run on Monday holidays, and lists a $9 one-way fare from Bar Harbor to Bangor; the same fare applies for a same-day round trip when completed in one day.

Island Explorer’s official Boston-to-Bar Harbor connection page lists the 2026 weekday connection as Boston South Station at 8:00 a.m., Bangor at 12:10 p.m., Downeast Transportation from Bangor at 1:30 p.m., and Bar Harbor Kebo Street at 3:10 p.m.

Transfer warning: the Bangor bus to Bar Harbor does not serve Bar Harbor Village Green. Downeast Transportation uses the Kebo Street stop for this route.

How Long Does The Boston To Bar Harbor Trip Take?

Boston to Bar Harbor takes about 7 hours by the cleanest same-day public-transport connection and about 5 to 6.5 hours by car in normal conditions. A train-first plan usually takes longer unless the Portland stop is part of the trip.

Amtrak to Portland plus a rental car can be a good compromise: a relaxed rail ride out of Boston, a food or waterfront stop in Portland, then a roughly three-hour drive to Bar Harbor. Amtrak to Brunswick adds more rail time but does not remove the long road leg.

• Use the bus route when the goal is car-free travel with one coordinated same-day plan.
• Use the train route when Portland or Brunswick is part of the trip, not just a transfer point.
• Use a rental car when you want to reach Acadia trailheads early or travel outside bus operating days.
• Use the flight option when the schedule matters more than rail scenery or ground cost.

Where To Stay After The Trip

Bar Harbor is the easiest base after a long travel day because restaurants, tour pickups, waterfront walks, and many lodging options sit close together. Staying in town also reduces the need to drive after arrival.

Travelers with a car can also price Southwest Harbor, Northeast Harbor, Trenton, and Ellsworth, especially during peak summer weekends. The trade is simple: outer towns can cost less, but Bar Harbor saves time once you start using Acadia’s shuttles and trailheads.

For comparing Bar Harbor stays against nearby towns on the same map, use the hotel map after you know your arrival plan:

Car Rental Or Shuttle For The Final Leg

A rental car is the safest fallback when the Bangor-to-Bar Harbor bus schedule does not match your arrival day. A shuttle works well for travelers staying in Bar Harbor village who do not plan to drive inside Acadia National Park.

Bar Harbor parking gets tight in summer, and Acadia’s most crowded trailheads can fill early. If your lodging is central and your trip falls during Island Explorer service, a car may sit parked more than expected.

Compare rental options only after you decide whether your trip needs a car for Acadia, side trips, or late arrivals:

Choose The Route That Fits Your Trip

The right Boston-to-Bar Harbor route depends on whether you want the train experience, the simplest car-free connection, or the least schedule risk. The train is pleasant, but the bus-to-Bangor route is usually the cleaner public-transport answer.

• Simplest car-free route: Concord Coach from Boston or Logan to Bangor, then Downeast Transportation to Bar Harbor on a weekday.
• Best rail-heavy route: Amtrak Downeaster to Portland, then rent a car or arrange a transfer for the final coastal leg.
• Best Acadia flexibility: rent a car from Boston, Portland, Bangor, or Bar Harbor airport, especially outside Island Explorer dates.
• Fastest route: fly from Boston Logan to Hancock County-Bar Harbor Airport, then use a short ground transfer.

For most travelers who specifically want a train, Portland is the sweet spot: you get the Downeaster ride, avoid pushing the rail leg farther than it helps, and still keep the final drive manageable. For travelers who mainly want to reach Bar Harbor without driving, skip the train and build the day around the Boston-to-Bangor bus connection.
