Acadia National Park is the best place in the north-eastern United States for coastal hiking, where granite mountains meet the Atlantic Ocean, pine forests slope to rocky shores and stone bridges cross historic carriage roads. The park lies mostly on Mount Desert Island in Maine, and it has trails for every level, from flat shoreline walks to iron-rung cliff climbs. This guide to Acadia National Park hikes explains where the park is, how to get there, how to get around, where to stay, the best trails, fees and reservations, the best time to go and how many days to plan.

Where Is Acadia National Park?
Acadia National Park is on the coast of Maine, in the far north-east of the United States, about 4.5 hours by car from Boston and 1 hour from Bangor. Most of it is on Mount Desert Island, with other sections on the Schoodic Peninsula and Isle au Haut. The park was the first national park east of the Mississippi River, created in 1916 through the donations of local landowners. It has 26 mountains, including Cadillac Mountain at 466 metres, the highest point on the US Atlantic coast, plus lakes, forests and a rugged coastline. The nearby town of Bar Harbor is the gateway.
How to Get to Acadia
The nearest airports are Hancock County-Bar Harbor Airport (BHB), with limited regional service, and Bangor International Airport (BGR), about an hour away, with flights from several US hubs. Portland (PWM) is about 3.5 hours by road and Boston Logan (BOS) about 5 hours. Most visitors drive, and a rental car is useful. In summer, seasonal bus services link Bar Harbor with Bangor, and Concord Coach buses run from Boston to Bangor. Check the park website for the latest transport options and any reservation requirements.
How to Get Around the Park
- Island Explorer bus: A free seasonal shuttle that connects Bar Harbor, trailheads and villages across the island. It operates from late June to early October, and it is a great way to avoid parking problems.
- Car: The Park Loop Road is a 27-mile scenic drive linking Sand Beach, Thunder Hole, Jordan Pond and Cadillac Mountain. Parking fills early at popular spots.
- Bicycle: More than 45 miles of carriage roads, built by John D. Rockefeller Jr. and closed to cars, are ideal for cycling and walking. Bike rentals are available in Bar Harbor.
- Walking: Many trails start near Bar Harbor, and some areas are walkable from town.
Where to Stay
Bar Harbor
Bar Harbor is the main base, with hotels, inns, shops, restaurants and boat tours. It is lively in summer, and it is the closest town to the park entrance. Book early for July to October.
Southwest Harbor and Northeast Harbor
These smaller villages on the quiet side of the island offer cosy inns and calm harbours, close to Acadia Mountain and Bass Harbor.
Camping
The park has campgrounds at Blackwoods and Seawall, which require reservations in season. Private campgrounds are plentiful.
The Best Acadia Hikes and Sights
Cadillac Mountain
The highest peak on the island offers panoramic views of Frenchman Bay and the Porcupine Islands. You can drive to the summit on a narrow road, which requires a timed vehicle reservation in the high season, or hike up the North Ridge Trail, about 4.4 miles return, or the South Ridge Trail. Sunrise from the summit is famous, and from October to March it is the first place in the United States to see the sun. Dress warmly, as it is windy and cold, even in summer.
Jordan Pond Path
A flat loop of 3.3 miles circles a clear glacial lake with the Bubbles, two rounded mountains, reflected in the water. The path is easy and suitable for families, and part of it crosses a boardwalk. Afterwards, visit the Jordan Pond House for tea and popovers on the lawn, a tradition for over a century.
Ocean Path and Sand Beach
Ocean Path runs for 4.4 miles along the coast from Sand Beach to Otter Point, passing Thunder Hole and tall cliffs. You can walk as much as you like and return by bus or car. Sand Beach is a small beach of crushed shells between granite cliffs, and the water is very cold.
Thunder Hole
Thunder Hole is a small inlet where waves surge into a rock chamber and release a booming sound and spray. It is best at half tide when the sea is rising, and conditions can be dangerous in big surf, so stay behind the barriers.
Precipice and Beehive Trails
These two trails are for experienced walkers who are comfortable with heights. The Precipice Trail climbs the east face of Champlain Mountain using iron rungs, ladders and narrow ledges, and it is closed for part of the year while peregrine falcons nest. The Beehive Trail is shorter but also exposed, with iron rungs on a granite cliff. Do not try either in wet weather. Both are very popular, so go early.
Bass Harbor Head Light
This small lighthouse stands on a cliff on the quiet side of the island, and it is one of the most photographed in Maine. A short path leads to rocks with views of the tower, which is best at sunset. The parking area is small, so go early.
Somes Sound and the Carriage Roads
Somes Sound is a fjord-like inlet that nearly divides Mount Desert Island in two. Trails such as Acadia Mountain and the Beech Mountain loop offer views of its steep sides. The carriage roads, with their stone bridges, are lovely for gentle rides or walks.
Tips for Hiking in Acadia
Acadia’s trails are short but steep, and the weather changes quickly, so carry layers and a rain jacket. Start early to avoid crowds and to find parking, particularly at Jordan Pond, Sand Beach and Cadillac Mountain. Wear boots or trail shoes with grip, since granite is slippery when wet. Bring plenty of water, snacks and sun protection, as many trails are exposed. Check tide times if you plan to walk the bar to Bar Island, which is accessible only at low tide. Leave no trace: stay on the trails to protect the thin soils and fragile plants, and pack out all rubbish. Insect repellent is helpful in early summer. If you are afraid of heights, choose the Ocean Path or the carriage roads over the iron-rung trails.
Eat Lobster and Local Food
Maine is famous for lobster, and Bar Harbor and the villages have lobster pounds, shacks and restaurants serving lobster rolls, steamed lobster and clam chowder. Wild blueberries, blueberry pie and ice cream are local favourites.
A Sample Three-Day Plan
On the first day, drive the Park Loop Road in the morning, stopping at Sand Beach, Thunder Hole and Otter Cliffs, walk part of the Ocean Path and have lunch in Bar Harbor. In the afternoon, hike around Jordan Pond and finish with popovers. Watch the sunset from Cadillac Mountain if you have a reservation, or from Bass Harbor Head Light. On the second day, climb the Beehive or the Gorham Mountain trail early, then cycle the carriage roads past stone bridges and lakes and relax with a lobster dinner. On the third day, take a boat tour to see puffins, whales or lighthouses, or drive to the Schoodic Peninsula for quieter coastline and fewer crowds. Leave a flexible morning for fog, which can hide the views but gives the coast a moody atmosphere.
History and Nature
Acadia sits in the traditional homeland of the Wabanaki people, who lived and travelled along this coast for thousands of years. In the nineteenth century, painters and wealthy families brought attention to the island. The park protects tidepools, spruce forest and rare birds such as peregrine falcons. Visit the Abbe Museum in Bar Harbor to learn about Wabanaki culture, and try tide pool exploring at low tide with care, as the organisms are fragile. The Nature Center near Sieur de Monts has gardens and exhibits for families.
Acadia FAQ
Which hike is best for beginners?
Jordan Pond Path, Ocean Path and the carriage roads are easy and scenic.
Do I need a reservation?
Some activities, such as driving up Cadillac Summit Road, require a timed reservation in season, and campgrounds need advance booking. Check the park website.
Is Acadia crowded?
Yes in July, August and October weekends. Go early, use the shuttle and try less-visited areas such as the west side or Schoodic.
Can I swim?
The ocean is very cold, even in summer. Echo Lake offers warmer swimming in lakes.
Are pets allowed?
Dogs are allowed on most trails on a leash, except on trails with iron rungs and in some areas. Check the rules.
Is Acadia worth visiting compared with other national parks?
Acadia is smaller than parks in the American West, but it is special for its combination of mountains, sea and charming villages. It suits travellers who love coastal scenery and easy-to-moderate hikes more than remote wilderness. It also works well in autumn, when foliage is spectacular.
Where can I see sunrise?
Cadillac Mountain is the classic spot, but other great viewpoints include Schoodic Point, Bass Harbor Head and Otter Cliffs. A reservation is needed for the summit road in season, and a sunrise hike on the North Ridge Trail avoids that.
Fees and Reservations
Entry requires a park pass, which can be bought per vehicle for a week or as an annual pass, and it is checked at some locations. Timed vehicle reservations are required to drive to the summit of Cadillac Mountain in the high season, and they are sold through the official recreation website. The Island Explorer shuttle is free. Prices and rules change from year to year, so check the National Park Service website for current fees and permits.
Best Time to Visit
The best time is from late May to October. Summer is warm and busy, with long days and boat trips. September and early October offer clear skies, fewer crowds and autumn colours, with peak foliage in mid-October. Spring is quiet, though some roads open late. In winter, the park is cold and snowy, with cross-country skiing and snowshoeing on carriage roads, and the Park Loop Road partly closed.
How Many Days Do You Need?
Two days cover the highlights, such as Cadillac Mountain, Jordan Pond, Ocean Path and the Park Loop Road. Three to four days allow more hiking, biking and a boat trip. A week lets you explore quieter areas and nearby towns.
Tours and What to See Next
Boat tours from Bar Harbor offer whale watching, puffin viewing and lighthouse cruises, and ranger-led programmes run in summer. Many visitors continue to Portland and the Maine coast, or to New England towns. For more US hiking, read our guides to the Angels Landing hike and the Half Dome hike.
