The ULTIMATE Guide to Exploring Acadia National Park in Maine

The secret is out about Acadia National Park Maine, with 2021 and 2022 smashing visitor records since the park opened more than 100 years ago.

It’s hard to stand out among the more than 4,600 islands that dangle from the Maine coastline, but you’ll see why Acadia National Park is known as the Crown Jewel of the North Atlantic Coast. You don’t have to pick between a mountain, forest, or shoreline here — you get them all in 47,000 acres.

About Acadia National Park Maine

The history of Acadia National Park is man’s love story with nature. It was first the Native Americans, then the French, who fell in love with this land. While historical marks seal those influences, it was the footprint of one man, George B. Dorr, who serenaded Acadia into our hearts forever.

“Few forests in the world, indeed, outside the rainy tropics, clothe themselves with such abundant life, and there are none that bring one more directly into touch with nature, its wildness and its charm.”

George B. Dorr, “Father of Acadia”

Dorr’s friend, Charles Eliot, had the idea while Dorr had the finances. When Eliot died suddenly in his late 30s, Dorr was left to continue the effort. A determined Dorr pressed on with congressional testimony, more land acquisition, and the then-unheard-of proposal to donate private land for public use.

In 1916, President Woodrow Wilson protected the land, and through several iterations of names and titles, it became Acadia National Park as part of the National Park Service (NPS) on Jan 19, 1929. The name “Acadia” is a tribute to the French influences and translates to “Heaven on Earth.”

“There is no other place along the Atlantic coast where so wide a range of geologic facts are shown or where such valuable material is offered for research. It will give a healthy playground to multitudes of hard-working men and women.”

Excerpt of writing from President Woodrow Wilson in the early 1900s

Dorr then teamed up with John D. Rockefeller, another wealthy conservationist who foresaw the erosion of nature from automobiles and orchestrated the very carriage roads that remain today where motor vehicles are banned.

The land became a playground for the affluent, with extravagant cottages and hotels dotting the rocky landscape. What luxuries the World Wars and the Great Depression didn’t destroy, a massive fire in 1947 did.

Land lovers Dorr and Rockefeller were the only wealthy to remain with the intent to build a legacy. In fact, Dorr exhausted his fortune preserving the trails. Acadia was his only true love because he never married to focus on this exquisite piece of land, and his love lives on today.

Acadia National Park Map: The Lay of the Land

Acadia National Park seemingly switches ecosystems as quickly as the breeze, and the Great Fire of 1947 even changed the landscape from what Dorr’s generation fell in love with.

“The fire of 1947 increased diversity in the composition and age structure of the park’s forests. It even enhanced the scenery. Today, instead of one uniform evergreen forest, we are treated to a brilliant mix of red, yellow, and orange supplied by the new diverse deciduous forests.”

Fire of 1947, NPS

Acadia National Park is primarily located on Mount Desert Island, which you can only access by driving through Trenton Maine. The city of Bar Harbor is outside the park limits but is a welcoming neighbor. On the larger island, there are several points of entry and interest:

Other islands included in Acadia National Park’s footprint include Isle au Haut, the Schoodic Peninsula, and the elusive Baker Island, which is accessible only via NPS tours.

Things to Know Now Before Your Acadia Visit

Exploring Acadia National Park comes with some nuances that every traveler needs to know to make the most of their time. Check these out before your visit.

Park Passes

Whether you’re in a car, on a bike, or walking, you’ll need a printed park pass. Buy and print your pass before you get to the park for immediate trail access. Park passes can also be purchased at the Hulls Cove Visitor Center or Schoodic Institute on the peninsula during seasonal hours.

NOTE: You can’t use a mobile device to show a code.

Cadillac Summit Road Reservations

Reservations are now required to drive Cadillac Summit Road, which spans 3 miles to the top of the park’s highest peak. With a newly repaved road open in spring 2023, it will offer a smoother ride for those who have a summit pass. The Island Explorer does NOT go on Cadillac Summit Road.

Camping Reservations

Acadia National Park campers also need to make camping reservations. Each campground has a different timeline for when bookings open, so set an alert to get your spot.

NOTE: You can download the app to get your park pass, camping pass, summit drive pass, and climbing permit.

Park Alerts

Use the park’s website or mobile app to check alerts throughout the year, which could include weather warnings, road closures, wildlife protection, or restoration activity. You can check the Storm Safety section before you head to the park each day you’re here.

Get Familiar With GPS

Spotty mobile service and the natural landscape make using a common mapping system obsolete. We recommend getting familiar with GPS coordinates to reach the right locations for different trails, lakes, and shorelines.

Things to Do at Acadia National Park

You’ve made it to Hulls Cove Visitor Center. Now what? You have a whole landscape of dynamic options ahead of you.

The general layout of the park is split between the east side — which is closer to Bar Harbor — and the west side — which is more remote and less crowded. If you’re taking the Island Explorer, check the routes to plan your path.

Acadia National Park Scenic Drives

Park Loop Road is the main scenic route through the park, making the most of your time by crossing paths with the main attractions. The 27-mile loop will take you to by Sieur de Monts, Sand Beach, Otter Point, Jordan Pond, and Cadillac Mountain.

From Park Loop Road, you’ll intersect with the 3-mile drive to the summit of Cadillac Mountain, which you’ll remember requires reservations from late May through late October. Summit reservations are only available at, not at the park.

You will need to choose between a summit sunrise trip or a daytime trip because those reservations are sold separately. Cadillac Mountain gets the first glow of the sun in the continental United States from early fall through early spring, making the sunrise trip very popular.

The Schoodic Loop goes 6 miles on a one-way road around the Schoodic Peninsula. Several picnic areas, rest stops, and scenic vistas are along the road.

Acadia National Park Hiking

Acadia National Park Maine hiking options cover the forests, lakes, coastlines, and summits. Also, you can choose trails that go out and back or loop around, with historic hiking options available.

Summit Hikes

The summit hikes offer incredible views and challenging pathways, but scrambling, climbing, and cliff walking are included in some of the more popular paths. If you are bringing your dog, please note that some of the more treacherous trails are off-limits to four-legged friends.

Coastal Hikes

Coastal hikes include places on Mount Desert Island and the nearby Schoodic Peninsula. You can parlay a coastal hike into tide-pooling, which is best experienced 90 minutes before and after low tide. With any coastal walk, watch out for slippery rocks and never turn your back on the sea.

Hiking Ocean Path will take you to Thunder Hole, where the rumbling sound of waves crashing at high tide reverberates through your whole body. A stairwell or switchback trail offers access close to the water, and you should arrive up to two hours before hide tide for the best chance of hearing the thunder roar.

Sensory Alert: Visitors with sensory issues might find this experience overwhelming. If that’s the case for you, we recommend that you bring earplugs.

Camping in Acadia National Park

Acadia National Park camping is growing in popularity, and you’ll need reservations for any campsite. Backcountry camping is not allowed, and the campgrounds close in the winter.

Duck Harbor Campground on Isle au Haut is only accessible by boat and is off-limits to dogs. Plus, lean-to shelters on Isle au Haut.

TIP: If you’re staying at Blackwoods Campground, book a horse carriage ride with Carriages of Acadia.

Lighthouses of Acadia National Park

Now that you’ve checked the sunrise at Cadillac Mountain off your bucket list, plan for a sunset view at Bass Harbor Head Lighthouse with its signature red light. The lighthouse is on the opposite end of the park from the main entrance near Bar Harbor.

NOTE: Parking is very limited, and the Island Explorer doesn’t stop here.

Two more lighthouses are overseen by Acadia National Park Maine. Baker Island has a lighthouse, but you can only get there with seasonal tours led by park rangers. The Bear Island Lighthouse can be viewed from tour boats on the water.

Islands of Acadia National Park

Many more options dot the landscape or bring people indoors in and around Acadia National Park. For example, Cranberry Isles is a town made up of five islands and is an extension of the park’s pristine nature while still being its own municipality.

Islesford is on Little Cranberry Island and has a seasonal historical museum with rotating exhibits. Isle au Haut is 26 miles southeast of Mount Desert Island and is open year-round through mailboats that provide passenger ferry service. You’ll find another lighthouse here, which is open for tours.

Stargazing & the Northern Lights at Acadia National Park

When darkness cloaks Acadia National Park Maine, all eyes go to the sky for some of the best celestial views that you can find in North America. There are several ideal spots for stargazing at Acadia National Park:

  • Cadillac Mountain: Check with the park ranger’s office for limited vehicle access to the summit at night.
  • Seawall Picnic Area: This is a great spot to see sweeping sky views close to Southwest Harbor or Bass Harbor.
  • Jordan Pond: The pond’s east side has the best viewpoints, but the path is a little bumpy and rocky, so watch your step.
  • Sand Beach: Sand Beach becomes Sky Beach at night, with plenty of space to spread out and enjoy the show.
  • Ocean Path: Park at Sand Beach near Thunder Hole to see great views to the north, south, and east. Bring a comfy chair for the rocky ground.

Bring a flashlight with a red filter or bulb so that you can still see where you’re walking but won’t create light pollution for others. For those hoping to see the northern lights (aurora borealis), plan your trip between December and March for the best chances.

NOTE: The Space Weather Prediction Center updates potential sightings around the clock.

Wild Gardens of Acadia National Park

Even 80 years after his death, nature lover George Dorr is still giving you flowers. The Wild Gardens of Acadia are on Mount Desert Island in the Sieur de Monts Spring region. More than 400 species of plants can be found on winding and whimsical paths.

The Sieur de Monts Nature Center is also nearby, which is as much a tourist attraction as a research facility for the ongoing studies being done on land, sea, and underwater.

Carroll Homestead

Near Southwest Harbor, guests can go back in time at the Carroll Homestead, where three generations of the family settled, worked, and lived on the land. The home is seasonally open for tours as a rare piece of living space that hasn’t been gobbled up by the wear and tear of weather and time.

Winter in Acadia National Park

Crisp air and blankets of snow create a kaleidoscope of new experiences in Acadia. While there are some accessibility limits, new portals open in winter that summer lovers don’t get to experience.

NOTE: The Bar Harbor Chamber of Commerce is the winter location for the visitor center. Visitor centers have scattered opening and closing dates before and after winter.

Walking in a Winter Wonderland

The 45 miles of carriage roads in Acadia National Park Maine were specifically designed for winter activities like cross-country skiing and snowshoeing. Volunteers groom the trails for guests, with access points available at the Brown Mountain Gatehouse and Hulls Cove Visitor Center.

Park Loop Road is partially closed off in the winter, leaving lanes of hiking, biking, and cross-country skiing trails for adventurers. A 1.4-mile route on Otter Point curves along the coastline with cliff views, with the path starting and ending at the Fabbri Picnic Area.

NOTE: Check with the Friends of Acadia Facebook or Twitter pages to see daily ski and trail conditions. You can use #SkiAcadia to get updates too.

Winter at Sand Beach

The winter storms of New England reshape the coastline in an endless seasonal cycle. The Sand Beach tide markings become an elegant dance of water, snow, and sand.

Be sure to weave the sand through your gloves to see small pieces of shell forming the brown brightness in a sea of blue and a landscape of white.
