Why Visit Acadia Byway
The Acadia Byway Maine, often called the Acadia All-American Road, is more than just a drive; it's an immersive journey through the heart of Acadia National Park and its surrounding communities. We consider it an essential experience for anyone exploring coastal Maine. This scenic loop offers unparalleled access to some of the most iconic landscapes in New England, where granite peaks dramatically meet the Atlantic Ocean. The byway stitches together ocean shoreline, coastal forests, and charming villages, providing a microcosm of Maine's natural beauty and cultural heritage.
Driving the Acadia Byway allows you to experience the park's diverse ecosystems firsthand. You'll witness the raw power of the ocean at Thunder Hole, stroll along the unique pink sands of Sand Beach, and marvel at the panoramic vistas from atop Cadillac Mountain. Beyond the natural wonders, the byway connects you to historic sites like the Jordan Pond House, famous for its popovers and tea, and the picturesque Bass Harbor Head Light Station.

It offers a convenient and comprehensive way to explore the park's highlights, making it ideal for first-time visitors and seasoned Acadia enthusiasts alike. The accessibility of its attractions, combined with the sheer beauty of the landscape, solidifies its place as a top US travel destination. You'll find yourself stopping frequently to capture photos, take short hikes, or simply soak in the breathtaking scenery.

Who It's Best For
The Acadia Byway caters to a wide array of travelers, making it a truly versatile destination. Our team finds it particularly well-suited for:

Getting There & Parking
Understanding how to get to Acadia Byway and navigating parking is crucial for a smooth visit. The byway itself is primarily formed by sections of Route 3 and the scenic Park Loop Road on Mount Desert Island.
How to Get There
The closest major airport is Bangor International Airport (BGR), about an hour's drive north of Mount Desert Island. From Bangor, you'll take I-95 South, then I-395 East, and finally US-1A South to Route 3, which will lead you directly to the byway and Acadia National Park.
Alternatively, Portland International Jetport (PWM) offers more flight options, but it's about a three-hour drive north to Acadia. If you're driving from points south, you'll generally follow I-95 North to Augusta, then take Route 3 East towards Ellsworth and Mount Desert Island.
Once you reach the Ellsworth-Trenton town line, you're officially on the Acadia All-American Road. Continue on Route 3 South, which will take you across Thompson Island and into Bar Harbor, the main gateway town for Acadia National Park.
Acadia Byway Parking & Fees
A park entrance pass is required year-round to access Acadia National Park, including the Acadia Byway. As of 2026, a non-commercial vehicle pass costs $35 and is valid for seven days. Individual passes for those entering by foot or bicycle are $20. An Acadia Annual Park Pass is available for $70, and the Interagency Annual Pass for $80 is a great option if you plan to visit multiple federal recreation sites. Non-US residents should note an additional $100 per person fee unless admitted with an Annual or America the Beautiful Pass.
Parking along the Acadia Byway and within Acadia National Park can be challenging, especially during peak season (June through October). Designated parking lots are available at popular spots like Cadillac Mountain, Echo Lake, Jordan Pond, and Sand Beach, but they fill up quickly. Parking outside of designated areas is not allowed.
Our top tip for Acadia Byway parking is to arrive early in the day, especially if you plan to visit popular spots like Bass Harbor Head Light Station, where the small lot holds only about two dozen vehicles and is often full by sunset. Consider utilizing the free Island Explorer shuttle bus system, which operates from late May through mid-October (full summer service typically June 23 through October 12, 2026) and connects various park attractions, campgrounds, and village centers, helping you avoid parking hassles.
Cadillac Mountain Vehicle Reservations: From May 20 through October 25, 2026, a vehicle reservation is required to drive to the summit of Cadillac Mountain. This reservation costs $6 and is separate from your park entrance pass. Reservations are released in timed slots (30% 90 days in advance, 70% two days prior) via Recreation.gov and are highly sought after, especially for sunrise. Hiking or biking to the summit does not require a vehicle reservation, but you still need a park entrance pass.
Top Things to Do
The Acadia Byway is your gateway to an incredible array of experiences, offering some of the best things to do at Acadia Byway and things to do in Mount Desert Island. Our team has curated a list of must-see and do activities:
- Drive the Park Loop Road: This 27-mile scenic drive is the centerpiece of the Acadia Byway, linking most of the park's headline sights. Much of it is one-way, guiding you past surf-pounded headlands and through the park's interior. Note that a one-mile section between Kebo Street and Sieur de Monts will be closed to all uses through June 12, 2026, excluding Memorial Day Weekend, for culvert replacement and wastewater system connection. Traffic will be rerouted through downtown Bar Harbor during this time.
- Witness Sunrise from Cadillac Mountain: As the highest point on the North Atlantic Seaboard, Cadillac Mountain offers breathtaking 360-degree views and is one of the first places in the US to see the sunrise. Remember, vehicle reservations are required to drive to the summit from May 20 through October 25, 2026.
- Explore Jordan Pond and Enjoy Popovers: This clear glacial pond is framed by the "Bubbles" mountains. Walk the easy shoreline loop trail, and then indulge in the famous popovers and tea at the historic Jordan Pond House. The restaurant is open from mid-May through late October, serving lunch and tea from 11:00 AM to 5:00 PM, with dinner available later. Reservations are recommended, as parking is extremely limited.
- Visit Bass Harbor Head Light Station: Located on the quieter western side of Mount Desert Island, this iconic lighthouse is perched on a stone foundation atop a rugged granite outcrop. It's a prime spot for sunset views, but arrive early due to very limited parking.
- Experience Thunder Hole and Sand Beach: Along the Park Loop Road, Thunder Hole offers a dramatic display as waves crash into a natural cavern, creating a thunderous roar and spray. Nearby, Sand Beach is a unique pink sand beach nestled in a small cove, perfect for a stroll or a dip in the chilly Atlantic waters.
- Bike or Walk the Carriage Roads: John D. Rockefeller Jr. built 45 miles of historic carriage roads, perfect for car-free exploration. These crushed-stone paths wind through the park's interior, featuring beautiful stone bridges and serene forest scenery. All carriage roads are now open, following springtime closures to prevent damage during the thaw.
- Hike the Trails: Acadia boasts 158 miles of hiking trails, ranging from easy strolls to strenuous climbs. Popular options include the Beehive Trail (strenuous, with iron rungs) and the Ocean Path, which offers relatively flat access to Sand Beach, Thunder Hole, and Otter Cliff. Note that Jordan Cliffs, Penobscot East, Precipice, and Valley Cove hiking trails remain closed until further notice to protect nesting peregrine falcons.
- Explore Bar Harbor: This vibrant town, adjacent to the park, offers a variety of shops, restaurants, and cultural attractions. It's a great base for exploring the Acadia Byway.
These things to do at Acadia Byway provide a rich tapestry of experiences, from coastal wonders to mountain vistas, ensuring a memorable trip to Mount Desert Island.
Best Time to Visit
The Acadia Byway offers distinct experiences throughout the year, but our team generally recommends visiting from late spring to early fall for the most comprehensive access and pleasant weather.
- Spring (May to early June): This is a beautiful time to visit as the park reawakens. Most of the Park Loop Road typically opens to motor vehicles around April 15th, though some sections may have temporary closures for maintenance. The Cadillac Summit Road is usually closed until May 20th, requiring reservations thereafter. You'll find fewer crowds than in summer, and the wildflowers are in bloom.
- Summer (Late June to August): Summer is peak season, offering the warmest weather and full access to all park facilities and services, including the Island Explorer shuttle. However, expect significant crowds, especially at popular attractions and in Bar Harbor. Reservations for Cadillac Mountain are essential. Book accommodations and dining well in advance.
- Fall (September to mid-October): Our team considers early fall to be the absolute best time to visit the Acadia Byway. The crowds begin to thin after Labor Day, the weather remains pleasant, and the fall foliage is simply spectacular, particularly in late September and early October. The Island Explorer shuttle typically runs through mid-October. Cadillac Mountain vehicle reservations are still required.
- Winter (Late October to April): While Acadia National Park is open year-round, many facilities and roads, including most of the Park Loop Road and Cadillac Summit Road, close from December 1st to April 14th. Winter offers a serene, snow-covered landscape for cross-country skiing and snowshoeing, but access is limited.
For optimal weather, fewer crowds, and vibrant fall colors, aim for September or early October. If you prefer warmer weather and don't mind the crowds, July and August are fantastic for enjoying all the park has to offer.
Where to Stay Nearby
Finding comfortable Acadia Byway lodging is key to a relaxing trip. While there are no hotels directly on the byway within the national park boundaries, numerous excellent options are available in the surrounding towns, particularly on Mount Desert Island.
- Bar Harbor: This is the most popular and convenient base for exploring the Acadia Byway. Bar Harbor offers a wide range of Acadia Byway lodging, from historic inns and charming bed & breakfasts to hotels and motels. You'll find options for every budget, along with abundant dining and shopping. Many accommodations are within walking distance to downtown attractions and Island Explorer shuttle stops. Our guide to Bar Harbor provides more in-depth lodging recommendations.
- Northeast Harbor & Southwest Harbor: For a quieter, more laid-back experience, consider these charming villages on the "quieter side" of Mount Desert Island. They offer a selection of inns, vacation rentals, and a more local feel. These towns still provide easy access to the Acadia Byway and park attractions, often with fewer crowds.
- Trenton & Ellsworth (Mainland): If you're looking for more budget-friendly Acadia Byway lodging or prefer to stay off Mount Desert Island, Trenton and Ellsworth on the mainland offer various chain hotels and motels. These towns are a short drive (15-30 minutes) to the entrance of Acadia National Park and the start of the byway.
- Acadia National Park Campgrounds: For those who prefer to sleep under the stars, Acadia National Park offers several campgrounds. Blackwoods Campground on the east side of Mount Desert Island is open year-round, though winter camping is walk-in only with a permit. Seawall Campground on the west side and Schoodic Woods Campground on the Schoodic Peninsula are typically open from May to October. Duck Harbor Campground on Isle au Haut is more primitive and accessible by boat. Reservations, especially during peak season, are highly recommended and can be made up to six months in advance.
No matter your preference, we recommend booking your Acadia Byway lodging well in advance, especially if you plan to visit during the busy summer or fall foliage seasons.
