One island in Maine has mountains, ocean cliffs, and lakes all inside a single park

Maine’s first eastern national park

You drive about 264 miles north of Boston, past lobster shacks and pine forests, and the road ends where granite mountains meet the Atlantic Ocean.

Acadia National Park covers about 49,000 acres spread across Mount Desert Island, the Schoodic Peninsula, and Isle au Haut. In 2025, a record 4,079,318 people came through.

Most of the park sits on Mount Desert Island, where peaks, ocean cliffs, lakes, and forest pack into a stretch of coast that hits different around every bend.

The Wabanaki called it “the sloping land”

The Wabanaki people lived here for thousands of years and called Mount Desert Island “Pemetic,” meaning “the sloping land.”

French explorer Samuel de Champlain showed up in 1604 and named it “Isle des Monts Deserts” after its bare, rocky summits.

Centuries later, George B. Dorr spent 43 years and his family fortune working to protect the landscape. President Woodrow Wilson designated Sieur de Monts National Monument in 1916.

It became Lafayette National Park in 1919 and took the name Acadia in 1929, the first national park east of the Mississippi and the first built entirely from private land donations.

Catch the first sunrise on the Atlantic seaboard

Cadillac Mountain stands about 1,530 feet tall, the highest point on the North Atlantic seaboard.

From roughly Oct. 7 through March 6, this is among the first spots in the continental United States to catch the sunrise.

A 3.5-mile summit road winds to the top, with pullouts looking over Frenchman Bay, the Porcupine Islands, and open ocean. You can also hike up via the 4.3-mile North Ridge Trail.

During peak season, you need a vehicle reservation to drive to the summit, so plan ahead.

27 miles of coastline from your car window

Park Loop Road runs 27 miles and connects the most popular landmarks on the eastern side of the park.

Much of the road is one-way, so it guides you past Sand Beach, Thunder Hole, Otter Cliffs, and Jordan Pond before climbing toward Cadillac Mountain.

Pullouts pop up every few minutes for photos, short walks, and trailhead access.

If you want to skip the parking hassle, the free Island Explorer bus system runs along the loop and throughout the park all season long.

Walk the only sandy beach in the park

Sand Beach is Acadia’s one sandy beach, a crescent tucked between granite cliffs and evergreen forest. The sand feels different underfoot because it is partly made of crushed shells.

From there, you can pick up Ocean Path, an easy 2.2-mile one-way trail that runs south along the cliffs. The trail takes you past Thunder Hole and Monument Cove before ending near Otter Cliffs.

Every turn opens a new angle on the shoreline, and you are right on the edge the entire walk.

Waves shoot 40 feet out of a rock cavern

Thunder Hole is a narrow inlet where incoming waves compress air inside a small cavern and produce a deep boom you can feel in your chest. Under the right conditions, water shoots up to 40 feet in the air.

Keep walking south and you reach Otter Cliffs, which rise roughly 110 feet above the ocean. North of Rio de Janeiro, you won’t find Atlantic headlands much higher than these.

Rock climbers come here for routes up to 60 feet on sheer granite faces with the sea crashing below.

Popovers at the pond house since 1893

Jordan Pond sits among the clearest and deepest lakes in Acadia, with the rounded twin peaks known as the Bubbles framing the far shore.

A 3.2-mile loop trail circles the water and gives you one of the most photographed angles in the park. The Jordan Pond House has served guests since 1893, and people line up for its warm popovers with butter and jam.

The area also works as a launching point for carriage road walks, with several trailheads branching out from the pond.

57 miles of car-free roads Rockefeller built by hand

Between 1913 and 1940, John D. Rockefeller Jr. financed and directed the construction of 57 miles of carriage roads, with 45 miles still maintained inside the park today. No motor vehicles allowed.

You share them with hikers, cyclists, and the occasional horse-drawn carriage.

Rockefeller also oversaw the building of 16 handcrafted stone bridges that span streams, gorges, and waterfalls.

Each bridge is steel-reinforced concrete faced with native granite, shaped to look like it grew out of the landscape. These roads are considered the finest example of broken-stone road construction in America.

Climb sheer cliffs on iron rungs bolted into granite

The Beehive Trail and Precipice Trail are among the most thrilling hikes in any national park. You climb sheer cliff faces using iron rungs, ladders, and narrow ledges with nothing but air beside you.

The Beehive rises about 450 feet in just under a mile, with views over Sand Beach and Frenchman Bay from exposed granite. The Precipice Trail goes up Champlain Mountain via iron rungs bolted into the rock.

It closes each spring and summer to protect nesting peregrine falcons. Skip both in wet weather or if heights are not your thing.

The only lighthouse on Mount Desert Island

Bass Harbor Head Lighthouse went up in 1858 and stands 56 feet above the water on a rugged cliff at the southern tip of Mount Desert Island.

It is the only lighthouse on the island and one of the most photographed in New England. You may recognize it from the America the Beautiful quarter in 2012.

Ownership passed from the U.S. Coast Guard to the National Park Service in 2020.

A short trail and wooden stairway lead you down the cliff face to a shoreline viewpoint where the light tower rises right above you.

Peregrine falcons, tide pools and humpback whales

Acadia supports about 40 mammal species and over 330 bird species, including bald eagles, loons, and barred owls.

Peregrine falcons went locally extinct here but came back through a reintroduction program and now nest on the park’s cliffs each spring.

At low tide, you can crouch over pools at Wonderland Beach and Ship Harbor and find sea stars, sea urchins, crabs, and anemones.

Whale watching cruises from nearby Bar Harbor take you into the Gulf of Maine, where humpback, minke, and finback whales surface.

Harbor seals bask on offshore rocks and show up on boat tours or from the Schoodic Peninsula.

The quiet side most people drive right past

The western half of Mount Desert Island goes by the “quiet side,” and the name fits. Fewer crowds, slower pace.

Somes Sound, a glacier-carved inlet, splits the island down the middle and is the only feature of its kind on the U.S. Atlantic coast.

Over on the mainland, about an hour from Bar Harbor, the Schoodic Peninsula draws the fewest visitors in the park. Waves crash against the rocky coastline at Schoodic Point with real force.

For true solitude, take the mail boat from Stonington to Isle au Haut, where primitive trails wind along remote coastal headlands.

Explore Acadia National Park in Maine

You can reach Acadia from Bar Harbor, the gateway town on Mount Desert Island, about 50 miles southeast of Bangor. The park stays open year-round, but many roads and facilities run on a seasonal schedule.

From late June through Columbus Day, the free Island Explorer bus picks you up around Bar Harbor and drops you at trailheads, beaches, and villages throughout the park.

Check the official website before you go for road openings, vehicle reservation windows, and current admission fees.
