While having your own vehicle provides the most flexibility for exploring the park and the surrounding areas, there are viable alternatives if you prefer not to drive or don't have access to a car.
Fastest Route: Driving Direct to Acadia
If you're looking for the quickest way how to get to Acadia National Park from Portland Maine, driving directly via Interstate routes is your best option. This route takes approximately 3 hours without stops and offers efficient travel while still providing glimpses of Maine's beautiful landscape.
The Direct Route: Step-by-Step Directions
- From Portland, take I-295 North, which will merge with I-95 North after about 46 miles
- Continue on I-95 North to Exit 182A (approximately 90 minutes from Portland)
- Follow I-395 East briefly to Exit 6A for US-1A East
- Continue on US-1A to Ellsworth
- In Ellsworth, take ME-3 East to Bar Harbor and Acadia National Park
š” Pro Tip: There's an alternative route that's almost the same driving time: Leave I-95 at Exit 113 and follow ME-3 East/US-1 North through Belfast and Searsport to Bar Harbor. This route has slightly more scenery but can add 10-15 minutes to your journey.
Driving Time Considerations
While the base driving time is about 3 hours, plan for these potential additions:
- Summer Traffic: Add 30-60 minutes during peak tourist season (June-August), especially on weekends
- Weather Conditions: Add 30+ minutes during winter snow or heavy rain
- Construction: Maine's short construction season means summer road work is common - check Maine DOT for updates
- Island Traffic: Once on Mount Desert Island, allow extra time to reach park destinations during peak season
I've made this drive dozens of times and find that leaving Portland early (before 8:00 AM) or after the evening rush (after 6:00 PM) provides the smoothest journey with minimal traffic delays.

The Scenic Coastal Route 1 Experience
For those wondering how to get to Acadia National Park from Portland Maine with maximum scenic value, Coastal Route 1 provides an unforgettable journey showcasing Maine's picturesque coastline, charming towns, and maritime culture. This route takes approximately 3.5-5 hours of pure driving time but deserves a full day (or even two) to truly appreciate the attractions along the way.
Why Choose the Scenic Route?
Maine's coastal Route 1 is considered one of America's most beautiful drives for good reason. Along this journey, you'll experience:
- Classic New England coastal scenery with rocky shores and hidden coves
- Charming fishing villages and historic coastal towns
- Iconic lighthouses and maritime landmarks
- Local seafood shacks and farm-to-table dining
- Artisan shops and galleries showcasing Maine craftsmanship
- Authentic Maine culture away from interstate highways
"The coastal route from Portland to Acadia isn't just transportation—it's a vital part of the Maine experience. Taking Route 1 transformed our journey into a series of delightful discoveries that became cherished memories of our trip." – From a review on Reddit's r/acadianationalpark
Scenic Route Itinerary Suggestions
To make the most of your coastal journey, I recommend breaking it into these segments:
Portland to Brunswick (25 miles)
Begin your journey by heading north from Portland on I-295, then transition to the more scenic Route 1 in Brunswick. Don't miss the opportunity to stop in Freeport for the L.L.Bean flagship store and outlet shopping.
Brunswick to Bath/Wiscasset (15 miles)
Continue along Route 1 to Bath, home to the Maine Maritime Museum and Bath Iron Works. Just a bit further is Wiscasset, known as "Maine's prettiest village" and home to the famous Red's Eats lobster shack, where summer lines are legendary but many say worth the wait.
Wiscasset to Rockland (40 miles)
This stretch takes you through Damariscotta, Waldoboro, and into Rockland. Art enthusiasts should visit the Farnsworth Art Museum in Rockland, celebrating Maine's role in American art with works by the Wyeth family.
Rockland to Camden (8 miles)
The short drive to Camden rewards you with one of Maine's most picturesque harbor towns. Take time to drive up to the summit of Mount Battie in Camden Hills State Park for spectacular views of Penobscot Bay.
Camden to Belfast/Searsport (20 miles)
Continue north through Lincolnville to Belfast, a revitalized historic shipbuilding town with a thriving arts scene, and Searsport, known for its maritime history and antique shops.
Searsport to Ellsworth/Bar Harbor (50 miles)
The final stretch takes you through Bucksport, where you can see the impressive Penobscot Narrows Bridge and Observatory. From Ellsworth, it's a straight shot on ME-3 to Bar Harbor and Acadia National Park.
Scenic coastal views are abundant along Maine's Route 1
Must-See Stops Between Portland and Acadia
The journey how to get to Acadia National Park from Portland Maine is filled with exceptional places worth stopping. Based on my experiences and local recommendations, these are the standout destinations that deserve your attention along the way:
Making the Most of Your Stops
If you're planning on taking the scenic route with multiple stops, I strongly recommend making it a two-day journey. Stay overnight in Camden or Rockland to break up the trip and give yourself time to truly appreciate these coastal gems. Both towns offer excellent accommodations ranging from charming B&Bs to waterfront hotels.
For those with limited time who still want to experience some highlights, prioritize Camden (for the Mount Battie view) and either Pemaquid Point or the Penobscot Narrows Observatory, depending on your chosen route.

Public Transportation Options
If you're looking for how to get to Acadia National Park from Portland Maine without a car, there are several public transportation options available, though they require some planning and potentially connecting between services.
Bus Service to Acadia/Bar Harbor
While there's no direct bus service from Portland to Acadia National Park, you can piece together a journey with these services:
Step 1: Portland to Bangor
- Carrier: Concord Coach Lines
- Journey time: Approximately 2.5 hours
- Cost: About $26-30 one-way
- Frequency: Multiple daily departures from Portland Transportation Center
- Amenities: Free WiFi, power outlets, comfortable seating
Step 2: Bangor to Bar Harbor/Acadia
- Option A: Downeast Transportation bus from Bangor to Bar Harbor
- Cost: Approximately $9 one-way
- Schedule: Limited service, typically operates five days a week
- Note: Schedules vary seasonally, with more frequent service during summer months
- Option B: Concord Coach Lines from Bangor to Bar Harbor (seasonal service)
- Cost: Approximately $15-20 one-way
- Schedule: Daily service during peak summer season only
The total journey time using buses is approximately 4.5-5 hours plus connection time in Bangor, which can vary depending on schedules. The total cost ranges from $35-50 one-way.
š” Pro Tip: If using bus transportation, I recommend staying in downtown Bar Harbor rather than trying to find accommodations deeper in the park. Once in Bar Harbor, you can use the free Island Explorer shuttle buses (operating late June through mid-October) to access various parts of Acadia National Park without needing your own vehicle.
Train and Bus Combination
Another option for those traveling from Boston or points south is to take the Amtrak Downeaster train to Portland, then connect to the bus options described above. The Downeaster offers a scenic route with amenities like a café car, but adds an extra connection to your journey.
Important: Public transportation schedules in Maine can change seasonally, with more options available during summer months. Always check the latest schedules and make reservations in advance, especially during peak tourist season.
Flying to Acadia National Park
For those wondering if flying is a viable option when considering how to get to Acadia National Park from Portland Maine, here are your options:
Charter Flights
The only direct air option from Portland to Bar Harbor/Acadia is via charter flight:
- Providers: Maine Instrument Flight, Air New England, and MAC Jets offer charter services
- Aircraft: Typically small planes like the Beechcraft Baron that can carry 4-5 passengers
- Flight time: Approximately 50 minutes
- Cost: Around $1,500 one-way for the entire aircraft (not per person)
- Departure: Portland International Jetport (PWM)
- Arrival: Hancock County-Bar Harbor Airport (BHB)
While this option is expensive, if you're traveling with a group of 4-5 people and value time over money, it could be worth considering. The aerial views of the Maine coastline are spectacular, adding a unique dimension to your Acadia experience.
Commercial Flights via Boston
A more affordable flying option is to take a commercial flight from Boston to Bar Harbor:
- Carrier: Cape Air offers regularly scheduled service from Boston Logan to Bar Harbor
- Flight time from Boston: Approximately 90 minutes
- Cost: Starting from about $199 one-way
- Schedule: Multiple daily flights during summer season; reduced schedule in shoulder seasons
This option requires first getting from Portland to Boston, either by car (2-hour drive), bus (Concord Coach Lines, approximately 2 hours), or connecting flight.
Getting Around After Flying
If you fly to Bar Harbor Airport (BHB), you'll need ground transportation to reach your accommodation and explore the park:
- Rental cars: Available at the airport but require advance reservation
- Taxis/Rideshares: Limited availability; best arranged in advance
- Island Explorer shuttle: Free service connecting the airport to Bar Harbor and Acadia destinations (late June through mid-October only)
My Take: Unless money is no object or you're extremely pressed for time, flying directly from Portland to Bar Harbor is rarely the most practical option. The driving route offers better value, flexibility, and the opportunity to experience Maine's coastal beauty along the way.
Best Time to Make the Journey
When planning how to get to Acadia National Park from Portland Maine, timing can significantly impact your experience. As someone who has made this trip in all seasons, here's my guidance on when to go and what to expect:
Seasonal Considerations
Weekday vs. Weekend Travel
Regardless of season, weekday travel between Portland and Acadia is generally smoother than weekend travel, especially during summer and fall foliage season. If possible, plan your journey for a Tuesday, Wednesday, or Thursday for the most pleasant experience. This applies to both driving and public transportation options.
If weekend travel is unavoidable during peak season, consider leaving Portland very early in the morning (before 7:00 AM) or in the evening after dinner to avoid the worst traffic congestion.

My Personal Experience: Three Years of Portland-to-Acadia Trips
Having made the journey from Portland to Acadia National Park more than a dozen times over the past three years, I've learned a few things about how to get to Acadia National Park from Portland Maine in the most enjoyable way. Here are some personal insights and experiences that might help you plan your own adventure:
My First Trip: The Learning Experience
My first journey to Acadia from Portland was a summer Saturday in July, and I made the classic rookie mistake of leaving mid-morning (around 10 AM). The direct route via I-295/I-95 was congested with vacation traffic, and by the time I reached Mount Desert Island, finding parking at popular park destinations was nearly impossible.
I ended up spending more time hunting for parking than enjoying the park itself. That evening, a park ranger gave me invaluable advice: "Either come very early or plan to use the Island Explorer." This transformed my subsequent visits.
Key Takeaway: Timing matters enormously. For summer visits, arrive early (before 9 AM) or plan to park in Bar Harbor and use the shuttle system.
The Scenic Route Discovery
On my third trip to Acadia, I decided to take the coastal Route 1 instead of the interstate. What was planned as a one-day journey turned into a wonderful two-day adventure as I discovered places like the Pemaquid Point Lighthouse and Camden. Since then, I've made it a tradition to take the interstate route when I'm focused on reaching Acadia quickly, but always take the scenic route on my return journey to Portland.
One September afternoon, I stopped at Camden Hills State Park on a whim and drove to the top of Mount Battie. The view of Camden Harbor and the islands of Penobscot Bay was so stunning that I ended up staying for sunset and booking a last-minute room in town. Sometimes the unplanned detours become the highlight of the trip!
Key Takeaway: Build flexibility into your schedule if possible. Some of the best experiences happen when you have the freedom to explore unexpected discoveries along the way.
Winter Adventure
Last February, I decided to experience Acadia in winter. The drive from Portland was peaceful with almost no traffic, though I had to be cautious about road conditions. Acadia was transformed into a quiet, snow-covered wonderland. Most facilities were closed, but the winter solitude allowed me to experience a completely different side of the park.
I stayed at one of the few open bed and breakfasts in Bar Harbor and spent three days cross-country skiing on the carriage roads and snowshoeing to normally crowded viewpoints that I had entirely to myself. The sunset from Cadillac Mountain with the winter light reflecting off the snow and ice was unlike anything I'd seen in summer visits.
Key Takeaway: Don't discount off-season visits. With proper preparation, winter trips offer unique experiences and perspectives that most visitors never see.
Public Transportation Test
Last summer, I decided to test the journey using only public transportation. I took the Concord Coach from Portland to Bangor, connected to the Downeast Transportation bus to Bar Harbor, and then relied on the Island Explorer shuttles within Acadia.
The experience was smoother than expected, though it required careful planning around bus schedules. The biggest advantage was being able to enjoy the scenery without focusing on driving, and not having to worry about parking. The biggest disadvantage was the limited flexibility – I couldn't easily visit some of the more off-the-beaten-path locations or make spontaneous stops.
Key Takeaway: Car-free travel to Acadia is entirely feasible during peak season but requires advance planning and a willingness to adapt to fixed schedules.
My Personal Recommendation
After numerous trips between Portland and Acadia, my ideal journey now combines elements from each experience:
- I travel during late September when the weather is still pleasant but crowds are reduced
- I take the direct interstate route on the outbound journey, leaving Portland by 7:00 AM
- I spend 3-4 days exploring Acadia, staying in a rental cottage in Southwest Harbor away from the main tourist areas
- For the return trip to Portland, I allow a full day to take the scenic Route 1, with planned stops in Camden and Rockland
This approach gives me the best of both worlds: efficiency when I'm eager to reach Acadia, and a leisurely exploration of coastal Maine when I'm in a more relaxed mindset heading home.
Essential Gear for Your Acadia Adventure
Once you've figured out how to get to Acadia National Park from Portland Maine, you'll want to make sure you're properly equipped for your adventure. Based on my experience, here are some essential items I recommend bringing or purchasing before your trip:
User Reviews: Gear Tested in Acadia
"The National Geographic Acadia trail map was a lifesaver when we wanted to explore some of the less traveled paths on the quiet side of the island. Cell service was spotty, but having the physical map meant we never got lost. It's waterproof too, which came in handy during an unexpected rain shower on the Beech Mountain Trail." - Sarah from Reddit
"Investing in proper hiking boots made all the difference on the iron-rung trails like Beehive and Precipice. The granite can be slippery even when dry, and I felt secure with the grippy soles. Worth every penny for the ankle support alone." - Mike from Amazon reviews
"Don't underestimate how chilly it can get on Acadia's coast, even in summer! Layers were essential for our trip - we started our Cadillac Mountain sunrise hike wearing everything we brought and were peeling layers off by mid-morning. The moisture-wicking shirts were perfect for keeping comfortable through temperature changes." - Jenna from Quora

Frequently Asked Questions
What is the driving distance from Portland, Maine to Acadia National Park?
The driving distance from Portland, Maine to Acadia National Park is approximately 170-175 miles via the fastest route using I-295 and I-95. If you take the more scenic coastal Route 1, the distance increases to about 200 miles. Driving time ranges from 3 hours via the direct route to 5+ hours via the scenic route (not including stops).
Remember that how to get to Acadia National Park from Portland Maine depends on your preferences for scenery versus speed. The direct route is more efficient, while Route 1 offers more memorable views and charming towns.
Is there a bus or train from Portland Maine to Acadia National Park?
There is no direct bus or train service from Portland to Acadia National Park. However, you can take a Concord Coach Lines bus from Portland to Bangor (about 2.5 hours), then connect to either the Downeast Transportation bus or seasonal Concord Coach Lines service to Bar Harbor (about 1.5 hours). The total journey takes approximately 5 hours plus connection time. There is no passenger train service to Bar Harbor or Acadia National Park.
For travelers coming from Boston or points south, you can take the Amtrak Downeaster train to Portland, then connect to the bus options described above. This multi-modal approach requires careful planning around schedules but is feasible for those who prefer not to drive.
What are the best stops between Portland and Acadia National Park for a one-day trip?
If you're making the journey in a single day but still want to experience some highlights along the way, I recommend limiting yourself to 2-3 strategic stops. My top recommendations for a one-day journey would be:
- Camden: Stop for a quick drive up Mount Battie for spectacular coastal views and a brief walk around the picturesque harbor.
- Penobscot Narrows Observatory: A relatively quick stop that offers incredible panoramic views from the tallest public bridge observatory in the world.
- If time allows, add either Wiscasset for a lobster roll at Red's Eats (though be prepared for a wait in summer) or Pemaquid Point Lighthouse for classic Maine coastal scenery.
With these limited stops, you can still reach Acadia with time to enjoy the park in the afternoon and evening. For a one-day trip to Acadia from Portland, efficient planning is essential.
Can I do Acadia National Park as a day trip from Portland?
While technically possible, I don't recommend doing Acadia National Park as a day trip from Portland. The 3-3.5 hour drive each way means you'd spend 6-7 hours in the car, leaving only a few hours to actually experience the park. Even focusing on just one section of Acadia would feel rushed and wouldn't do justice to this magnificent national park.
If you absolutely cannot stay overnight near Acadia, I suggest focusing your brief visit on either:
- A drive along the Park Loop Road with brief stops at key viewpoints like Thunder Hole and Jordan Pond
- A drive to the summit of Cadillac Mountain (reservation required May-October) and one short hike
However, to truly appreciate things to do in Acadia National Park in one day, I strongly recommend staying at least one night in Bar Harbor or another nearby town.
Where should I stay between Portland and Acadia National Park?
If you're looking to break up the journey with an overnight stay, several charming towns make excellent stopping points between Portland and Acadia National Park:
- Camden: Approximately the halfway point and one of Maine's most beautiful coastal towns with excellent accommodations ranging from luxury inns to budget-friendly options.
- Rockland: Just south of Camden, offers a more working waterfront feel with great restaurants and access to the Farnsworth Art Museum.
- Belfast: A bit further up the coast, this revitalized historic town offers a less touristy atmosphere with charming B&Bs and a walkable downtown.
- Boothbay Harbor: Though slightly off the direct route, this quintessential Maine harbor town offers plenty of accommodation options and activities.
For specific recommendations on where to stay between Portland and Acadia National Park, I personally recommend the Camden Harbour Inn for luxury travelers and the Whitehall in Camden for mid-range budgets.
Conclusion: Your Perfect Portland to Acadia Journey
The journey from Portland to Acadia National Park is more than just a means to an end—it's an integral part of the Maine experience that can enhance your overall vacation. Understanding how to get to Acadia National Park from Portland Maine allows you to make informed choices that align with your travel preferences, timeline, and interests.
Whether you opt for the efficient interstate route to maximize your time in Acadia, choose the scenic coastal path to absorb Maine's maritime charm, or utilize public transportation options for a car-free adventure, each approach offers its own unique benefits and memorable experiences.
My most important recommendations after years of making this journey:
- Consider your priorities: Speed versus scenery, flexibility versus relaxation.
- Plan according to the season: Summer requires more attention to traffic and crowds, while off-season travel needs attention to open services and weather conditions.
- Build in buffer time: Even the direct route can face unexpected delays, especially during peak season.
- If possible, take different routes: Consider taking the fast route one way and the scenic route the other to experience the best of both worlds.
- Don't rush: If time allows, consider breaking the journey with an overnight stay to fully appreciate the coastal towns between Portland and Acadia.
Whichever path you choose for your journey from Portland to Acadia National Park, you're in for a treat. The rugged coastline, charming towns, and ultimately the awe-inspiring landscapes of Acadia itself create a quintessential Maine experience that keeps visitors returning year after year.
Safe travels, and enjoy every mile of your Maine adventure from Portland to Acadia National Park!
