Portland is Maine's hip and happening largest city: a coastal hub that's home to the state's busiest airport. Continue just over 150 miles north along Maine's storied coast, and you'll reach Acadia National Park in Bar Harbor. There are more than 47,000 protected acres within the park's boundaries: some 30,300 of them here on Mount Desert Island. To see Acadia's sights is to appreciate Maine in all of its wild and rugged diversity. Within the park, Cadillac Mountain—the highest point on the Atlantic Seaboard—is the first point in America to greet the sun each morning from early October through early March.

How will you travel between these two popular destinations in Maine? It's best to have your own car, but if you are determined and creative or willing to drop some cash, you can also make the trip via Uber, bus, or plane. Keep in mind that Acadia is at times so crowded in the summer that traffic becomes incredibly congested. Even if you've driven your own or a rental car to Bar Harbor, you may want to trade it for a seat on the free Island Explorer shuttle bus that stops at points in town as well as within the park.

Rental cars are readily and easily available at Portland International Jetport, which is convenient for travelers who are flying into Maine's most popular airport. 

What Is the Fastest Way to Get From Portland, Maine, to Acadia National Park?

If you're in a rush to reach Acadia and its well-known natural features, then driving on Maine's interstates is your fastest option. Typically, entering Acadia National Park into a GPS will route you out of Portland on I-295, which merges 46 miles later with I-95. Continue north to Exit 182A and follow I-395 East a short distance to Exit 6A for US-1A. In Ellsworth, pick up ME-3 East to Bar Harbor and Acadia National Park. You can make the trip in almost the same time by leaving I-95 at Exit 113 and following ME-3 East/US-1 North through Belfast and Searsport en route to Bar Harbor. 

How Long Does It Take to Drive?

Following either route described above, you'll reach Acadia in just under three hours from the time you left Portland if you don't make any stops along your drive. The two options differ in time by a matter of minutes, and road work, accidents, and traffic can affect your total travel time.

Is There a More Scenic Driving Route to Acadia?

There definitely is. In Maine, Coastal Route 1 is famous for showing off ocean views and for wandering through some of Maine's most picturesque towns. Drive straight from Portland to Acadia, sticking to Route 1 until it meets Route 3 in Ellsworth, and you can make the trip in about three-and-a-half hours: not much more than if you'd driven on far-less-interesting interstates. But will you really be able to resist stopping to shop at the L.L. Bean flagship and outlet stores in Freeport? Waiting in line at Red's Eats in Wiscasset for a lobster roll? Visiting Rockland's art museums and walking along the stone breakwater out to Rockland Breakwater Light? Pausing in Camden to admire the pretty harbor, shop, and drive to the top of Mount Battie? Taking the elevator to the top of the Penobscot Narrows Bridge Observatory in Stockton Springs to admire the view from the tallest public bridge observatory in the world? There are so many temptations along this scenic route that you can easily spend a full day—or even two days—making your way from Portland to Acadia National Park and making memories all along the way.

Is There a Bus That Goes From Portland, Maine, to Acadia National Park?

Have you heard that Maine saying, "You can't get they-uh from hee-ah"? Well, you can't take a bus from Portland to Acadia… not directly, at least. But if you're feeling adventurous and have some time on your hands—and either don't have access to a car or a license to drive one—there are ways to hack public transportation. You'll first have to take a Greyhound or Concord Coach bus from Portland to Bangor. That will cost you about $26. Bangor is still 45 miles from Acadia National Park, but you can take a Downeast Transportation bus there for $9. Schedules are limited, though, and even if you could connect from one bus straight to the next, you'd be looking at five hours' ride time minimum.

When Is the Best Time to Travel to Acadia National Park?

Try to time your trip for summer or fall, when Acadia is at its most beautiful. While summer weekends can be crowded, midweek is more manageable. Visit in August for the best chance of finding water temperature warm enough for swimming and in late September or early October to see fall colors. Keep in mind that the park is closed in the winter, from November through April.
