Miss your window in Bar Harbor and the ocean traps you there for nine hours

Maine’s island town disappears underwater

You can walk to an island from downtown Bar Harbor, but only if you time it right.

The gravel path vanishes under 12 feet of Atlantic water twice a day, and if you miss your window, you’re stuck for nine hours. That’s the kind of place this is.

A small Maine town on Mount Desert Island where the national park next door pulls 4 million visitors a year, the sunrise hits first, and a Rockefeller built the roads. The tidal bar is just the beginning.

The Wabanaki called it “the sloping land”

The Wabanaki people lived on this island for thousands of years and named it Pemetic, meaning “the sloping land.”

French explorer Samuel de Champlain showed up in 1604 and called it Isle des Monts Deserts, or the island of barren mountains.

The town started as Eden in 1796 and changed its name to Bar Harbor in 1918 after the sandbar connecting it to Bar Island.

By the late 1800s, families like the Rockefellers, Vanderbilts and Astors built summer estates they called “cottages.” A wildfire in 1947 wiped out dozens of them.

Catch the first sunrise in America from Cadillac Mountain

Cadillac Mountain rises 1,530 feet, the highest point on the North Atlantic seaboard. From Oct. 7 through March 6, it’s the first place in the United States to catch the sunrise.

A 3.5-mile road winds to the top, where you can look out over Frenchman Bay and the Porcupine Islands. You need a vehicle reservation from May 20 through Oct. 25, and they sell out fast.

Skip the car and hike the North Ridge Trail instead, a 4.4-mile round trip that gets you there without a reservation.

A gravel path to Bar Island appears twice a day

A natural gravel land bridge connects downtown Bar Harbor to Bar Island, right inside Acadia National Park. You get about 1.5 hours on either side of low tide to cross, and the walk runs about half a mile.

On the other side, a short trail leads to a viewpoint looking back at Bar Harbor and Frenchman Bay. Lose track of time and you’ll wait roughly nine hours for the next low tide.

This sandbar gave the town its name when residents renamed it in 1918.

Thunder Hole blasts spray 40 feet into the air

Waves push into a narrow inlet carved from rock, force air out of an underwater cavern, and the whole thing booms like a cannon. That’s Thunder Hole, and under the right conditions, spray shoots over 40 feet high.

Show up about one to two hours before high tide for the best effect.

From there, the Ocean Path runs 2.2 miles along granite cliffs from Sand Beach to Otter Point, passing Monument Cove and the Otter Cliffs. The first stretch to Thunder Hole covers 0.7 miles and works for all ages.

Bike 57 miles of car-free roads a Rockefeller built

John D. Rockefeller Jr. spent 27 years building 57 miles of carriage roads through Acadia, finishing in 1940. No cars allowed, then or now.

You can walk, bike, ride horses, or take a horse-drawn carriage along roads that follow the shape of the land through forests and past ponds.

Rockefeller also put up 16 stone bridges, each with its own design cut from native granite.

Landscape architect Beatrix Farrand chose the plantings, picking native shrubs and trees to frame the views along the way.

Popovers and jam on the lawn at Jordan Pond House

Jordan Pond House has served tea and warm popovers since the 1890s.

Nellie McIntire started the tradition, bringing out popovers with butter and strawberry jam on the lawn overlooking Jordan Pond.

The original building burned in the 1970s, and a rebuilt version opened in 1982, keeping the same menu and the same view. You sit looking out at the Bubbles, two round-topped mountains framing the north end of the pond.

In summer, the restaurant serves more than 2,000 people a day, so grab a reservation early.

Humpback whales surface right off Bar Harbor

Whale watching boats leave straight from Bar Harbor’s harbor and head into the Gulf of Maine. You’ll likely spot humpback whales, finback whales (the second-largest species on the planet), and minke whales.

Harbor seals, porpoises, dolphins, bald eagles and puffins show up too. The season runs from April through October.

Research interns from Allied Whale at the College of the Atlantic ride along on the tours, collecting data on every whale they see.

Stroll a century-old path past Gilded Age estates

The Shore Path follows the edge of Frenchman Bay for just under a mile, and it’s been open to the public since 1880.

You start at Agamont Park near the town pier and walk past historic inns, former Gilded Age estates, and Balance Rock, a glacial boulder the Ice Age dropped right on the shore.

Views stretch out to the Porcupine Islands, Egg Rock Lighthouse and the Schoodic Peninsula.

The Bar Harbor Village Improvement Association maintains it, and private landowners along the route keep it open to everyone.

12,000 years of Wabanaki history at the Abbe Museum

The Abbe Museum in downtown Bar Harbor covers 12,000 years of Wabanaki history and living culture.

The Wabanaki Confederacy includes four federally recognized tribes in Maine: the Maliseet, Mi’kmaq, Passamaquoddy and Penobscot.

Dr. Robert Abbe founded the museum in the early 1900s, and it became Maine’s first Smithsonian Affiliate in 2013. A second location at Sieur de Monts Spring inside Acadia opens seasonally with archaeological exhibits.

The museum now centers Wabanaki voices in telling their own stories through a decolonized approach.

Drive the 27-mile Park Loop past cliffs and coves

The Park Loop Road runs 27 miles through Acadia and hits every major sight: Sand Beach, Thunder Hole, Otter Cliffs, Jordan Pond and Cadillac Mountain.

Parts of the road go one-way, running clockwise along the eastern coast. You’ll need a park entrance pass at $35 per vehicle, good for seven days.

On the western side of Mount Desert Island, the “Quiet Side” holds small fishing villages like Bass Harbor, Southwest Harbor and Tremont.

Bass Harbor Head Lighthouse sits on a cliff at the island’s southern tip and draws photographers from everywhere.

Iron rungs, freshwater swimming and dark skies

The Beehive Trail sends you up exposed granite ledges using iron rungs and ladders bolted into the rock. If you want calm water instead, Echo Lake Beach gives you freshwater swimming on the island’s quieter western side.

Somes Sound, often called the only fjard on the East Coast, cuts Mount Desert Island nearly in half. The Schoodic Peninsula sits on the mainland and gives you Acadia’s rocky coast without the crowds.

After dark, head to Cadillac Mountain or any high point in the park for dark skies you rarely find in the eastern United States.

Explore Bar Harbor and Acadia in Maine

You can reach Bar Harbor by car on Maine State Route 3. It sits on Mount Desert Island in Hancock County, about five hours north of Boston.

Flights from Boston land at Hancock County-Bar Harbor Airport, and The CAT high-speed ferry runs from Yarmouth, Nova Scotia.

Once you’re on the island, the free Island Explorer shuttle connects downtown Bar Harbor to campgrounds and trailheads throughout the park’s seasonal operating period, so you can leave the car behind and still reach the trails.
