Acadia National Park

Most of Acadia sits on Mount Desert Island, a chunk of land that glaciers ground down and rounded off during the last ice age. The moving ice scooped out valleys, carved deep basins that later filled with water to become ponds, and left behind the bald granite summits that give the park its shape. The rock here is a warm pink granite, and where the forest thins near the tops you walk right across the bare stone with the ocean laid out below you.

The crown of it all is Cadillac Mountain, which at 1,530 feet is the highest point along the entire United States Atlantic coast. For much of the year, from fall through early spring, the summit is the very first ground in the country to catch the morning sun, so people climb up in the dark to watch the day begin over Frenchman Bay and its scatter of small Porcupine Islands. Below the peaks, cold clear ponds like Jordan Pond sit ringed by spruce, and along the shore the sea has carved beaches, cliffs, and booming caves out of the granite.

One thing sets Acadia apart from almost any other park. It holds 45 miles of unpaved carriage roads, broad gravel lanes built by John D. Rockefeller Jr. and closed to cars, laced together by handsome stone bridges. You can walk, bike, or ride a horse on them for hours without ever meeting an engine. Between the carriage roads, the ocean paths, and the summit trails, Acadia is a park you explore on foot as much as by car.

• Hulls Cove Visitor Center entrance, off ME-3 near Bar Harbor, is the main way in. It is the front door to the Park Loop Road and the best place to start, with maps, rangers, and the road up to Cadillac Mountain close by.
• Park Loop Road, reached off ME-3 on Mount Desert Island, is the scenic one-way-in-places drive that strings together Sand Beach, Thunder Hole, and the ocean overlooks. It is open spring through fall and closed for the winter.
• The Schoodic Peninsula entrance, off ME-186 near Winter Harbor, opens onto the park's only mainland section. It stays open year-round and sees far smaller crowds than the island.
• Most visitors reach the park by driving up US-1 along the Maine coast, then following ME-3 out onto Mount Desert Island. From Bangor it is about an hour southeast on ME-3; from Portland, allow roughly three hours up the coast.

• Bar Harbor is the lively resort town just outside the park and the gateway to it, with restaurants, shops, and boats heading out for whale watching in season.
• Thunder Hole is a narrow slot in the shore where an incoming wave gets squeezed into a sea cave and booms like distant thunder, throwing spray into the air. It is best on a rising mid tide with some swell running.
• Bass Harbor Head Lighthouse, a small brick tower on the granite ledges of the quiet side of the island, is the most photographed lighthouse in Maine and a short, easy walk to reach.
• Isle au Haut is a remote island piece of the park reached by a mailboat ferry from the fishing town of Stonington, for those who want the wildest and least-crowded corner of Acadia.

Long before it was a park, this coast was home to the Wabanaki peoples, whose name means People of the Dawnland, a fitting name for a place that greets the country's first sunrise. The nations of the Wabanaki, including the Penobscot, Passamaquoddy, Maliseet, and Mi'kmaq, fished the bays, gathered along the shores, and traveled these waters by birchbark canoe for thousands of years. Their deep connection to Mount Desert Island continues today, and the Wabanaki remain an active, living presence on this land, not a story from the past.

In the 1800s wealthy summer visitors, sometimes called rusticators, discovered the island's beauty and began building grand summer homes. As development pressed in, a small group of people who loved the place set out to save it. Led by George B. Dorr, a tireless Boston gentleman who gave much of his own fortune and years of his life to the cause, they gathered up parcels of land and gave them to the public. Their gift became a national monument in 1916, then Lafayette National Park in 1919, the first national park in the eastern United States. In 1929 it was renamed Acadia, the name it carries today.

The park owes much of its character to John D. Rockefeller Jr., who summered on the island and worried that the coming of the automobile would spoil its quiet. Between 1913 and 1940 he financed and helped design 45 miles of broad gravel carriage roads, closed to cars, along with sixteen graceful stone bridges. Built by hand and fitted carefully into the land, they let people move through the park on foot, by bicycle, or on horseback, and they remain one of Acadia's greatest treasures.

In the 1930s the Civilian Conservation Corps came to Acadia, as it did to parks across the country, building trails, fighting fires, and shaping the landscape you walk today. A great fire swept much of the eastern half of Mount Desert Island in 1947, burning many of the old summer estates. The forest that grew back afterward, full of birch and aspen, is part of why Acadia blazes with color each fall.

• Acadia was the first national park east of the Mississippi River, and unlike the great western parks carved out of federal land, it was assembled almost entirely from private land that people donated for the public to enjoy.
• For much of the year, from about October through early March, the summit of Cadillac Mountain is the very first place in the continental United States to see the sunrise.
• The park's 45 miles of carriage roads were paid for and shaped by John D. Rockefeller Jr., and they were built with a broken-stone base and crowned surface so rainwater sheds off, which is why they have held up for a century.
• Sixteen hand-built stone bridges lace the carriage roads together, and no two of them are alike; each was designed to fit its own stream, cliff, or ravine.
• The name Cadillac Mountain comes from a French nobleman, Antoine de la Mothe Cadillac, who once held a land grant here, and yes, the car brand is named after the same man.
• A huge fire in 1947 burned much of the eastern side of Mount Desert Island. The birch and aspen that grew back afterward turn brilliant gold and orange in autumn, giving Acadia some of the best fall color in the East.
• Sand Beach is unusual because much of its 'sand' is actually made of crushed shells and bits of sea creatures ground up by the waves, not just rock.
• The island got its name from the French explorer Samuel de Champlain, who in 1604 called it Isle des Monts Deserts, meaning island of the bare mountains, for its treeless granite summits.

• An entrance fee applies, sold as a per-vehicle pass good for seven days; check the park website for current rates, and note that interagency annual passes are accepted.
• The Hulls Cove Visitor Center is open roughly May through October and is the best place to start, with maps and ranger advice.
• To drive up Cadillac Mountain during the busy season, a timed vehicle reservation is required, especially for the popular sunrise slots, so book ahead through the reservation website.
• The Jordan Pond House, a historic restaurant inside the park, is famous for its popovers and afternoon tea with a view across the pond to the rounded Bubbles.
• The carriage roads are open to walkers, bikers, and horses but closed to motor vehicles, making them a peaceful way to see the park.
• Sand Beach offers scenic saltwater swimming, but the water stays cold, usually around 55 to 60 degrees Fahrenheit even in summer, so it is bracing.
• Bar Harbor, just outside the park boundary, is the nearest town and offers full services, lodging, and dining.

Yes. Acadia charges a per-vehicle entrance pass that is good for seven days, and interagency annual passes are accepted. Check the National Park Service website for the current rate before you go, since prices change from year to year.

The park is open year-round, but many roads and services scale back in the cold months. The Park Loop Road and the summit road up Cadillac Mountain close for winter, usually from around December into spring, and the Hulls Cove Visitor Center is generally open May through October. The Schoodic Peninsula side stays open all year.

In the busy season, yes. A timed vehicle reservation is required to drive up the Cadillac Mountain summit road, and the sunrise slots in particular fill fast. Book ahead through the reservation website. Outside the busy season and once the road closes for winter, the reservation is not needed.

You can drive the Park Loop Road and hit the highlights in a full day. To hike a summit, walk the carriage roads, catch a sunrise on Cadillac Mountain, and get out to a quieter corner like Schoodic Point, give it two or three days. Many visitors happily spend a week.

Summer is warmest and busiest, with everything open. Early fall, from mid-September into October, is a favorite for cooler air, smaller crowds, and brilliant leaf color across the island. Spring is quiet and green. Winter is peaceful and beautiful for those prepared for cold and closed roads.

The classic sights are the sunrise or a wide view from Cadillac Mountain, the ocean drama of Thunder Hole and Sand Beach, a walk or bike ride on the carriage roads, popovers at the Jordan Pond House, and the picture-perfect Bass Harbor Head Light. For fewer people, cross to Schoodic Point on the mainland.

Acadia is fairly pet-friendly. Leashed dogs are welcome on most hiking trails and on the carriage roads, which is unusual for a national park. A few steep ladder trails, Sand Beach in summer, and some public buildings are off limits. Bring water, keep pets leashed, and check the park website for the current rules.

The park has campgrounds on the island and on the Schoodic Peninsula, which fill early in summer and take reservations. There is no hotel lodging inside the park itself. For rooms, inns, and restaurants, the town of Bar Harbor just outside the boundary is the main hub, with other small towns scattered around the island.

Acadia's granite is beautiful but can be dangerous. Wet rocks near the surf, especially at Thunder Hole and Schoodic Point, are extremely slippery, and rogue waves have swept people off the ledges, so stay well back from the water. On the summits, weather changes fast and fog rolls in quickly, so carry layers, water, and watch your footing on the bare rock.

For part of the year, roughly October through early March, Cadillac Mountain is the first place in the continental United States to see the sunrise. It comes down to a mix of how far east the peak sits, how tall it is at 1,530 feet, and the tilt of the Earth in those months. In summer, a few spots farther north and east see the sun first.
