National Parks In Maine

1- Acadia National Park

Acadia National Park is a stunning national park in Maine to visit in fall.

Acadia National Park sits along the rocky shores of Maine’s coast.

Most of its 47,000 acres (19,000 ha) is spread across Mount Desert Island, with sections on the Schoodic Peninsula and Isle au Haut.

With shimmering lakes, rolling mountains, and lush forests, Acadia is one of Maine’s most spectacular national parks.

George B. Dorr and Charles W. Eliot made the park a reality through land donations and advocacy at the state and federal levels.

They understood the threats that overdevelopment would pose to this coastal treasure and acted quickly to prevent it.


Philanthropist John D. Rockefeller, Jr., further aided the park’s expansion by constructing carriage roads.

In 1916, President Woodrow named the area the Sieur de Monts National Monument, but it was renamed Acadia National Park a decade later, making it the first national park established from privately donated land.

Wetlands, forests, mountains, freshwater lakes and ponds are among the ecosystems found in Acadia National Park.

The park is covered with trees and shrubs, with over 1,100 plant species, including mosses, mushrooms, lichens, ferns, wildflowers, and even freshwater and marine plants.

It has a diverse range of wildlife. Bats, beavers, coyotes, foxes, deer, otters, raccoons and bobcats are just a few of the animals that have been spotted.

In the park’s intertidal zones, you can find crabs, sea stars, whelks, urchins, periwinkles and mussels.

Seals, dolphins, whales and other marine mammals frolic in the waters off Mount Desert Island’s shore.

Several reptiles, amphibians and bird species live in the park, including peregrine falcons, songbirds, sea birds, herons and harlequin ducks.

Things To Do In Acadia National Park

Climb Cadillac Mountain

On a clear summer day, cycling or driving downhill along Cadillac Mountain road offers a panoramic view of Acadia National Park’s landscape of lakes.

Cadillac Mountain, at 1,530 ft (466 m), is not only the park’s highest peak but also the highest peak along the North Atlantic seaboard.

It is known for its beautiful sunrises, and from late fall to early spring, it’s the first place in the country to see the sunrise.

The short, paved Cadillac Summit Loop Trail, which affords stunning views of the glaciated coastal and island environment, allows visitors to feel the sun’s rays while ascending to the peak.

It connects the park’s attractions and natural wonders, beginning near the Hulls Cove Visitor Center on the island’s north shore in Bar Harbor.

A challenging climb to the peak of Cadillac Mountain is among the highlights, as are other attractions like Sand Beach, Great Head, Thunder Hole, Otter Point and Jordan Pond.

Explore The Carriage Roads

The Carriage Roads are a 57-mile (92-km) network of paved roads built by John D. Rockefeller Jr. between 1913 and 1940.

The paths circling Jordan Pond, Bubble Pond, and Eagle Lake are still popular today for hiking, bicycling, horseback riding and carriage rides.

They highlight the park’s most beautiful views.

Vehicles are not allowed on these carriage roads, which are kept open in winter for cross-country skiing, snowmobiling and snowshoeing.

Explore Schoodic Peninsula

The sun setting along the rocky coast in Maine is a stunning sight.

The scenic Schoodic Peninsula is on a separate peninsula and to the north of the rest of the park, which is mainly on Mount Desert Island.

Despite having features similar to Mount Desert Island, this area is a less visited and more secluded peaceful environment.

It has a rugged landscape of granite headlands, a craggy shoreline, and several hiking trails that take hikers through pine and spruce-fir forests.

Listen To The Waves At Thunder Hole

Thunder Hole is a natural rock inlet where waves crash with a thunderous boom in one of the top Maine national parks.

Thunder Hole is a spectacular location in Acadia National Park, where you can hear the thunderous sound of the waves crashing against the Maine cliff walls.

The sound occurs when the waves crash into a natural entryway carved into the rocks, colliding with the air entering the cave as the waves recede.

Experiencing this phenomenon requires good timing, and when the tide is high, water can spray as high as 40 feet (12 m) into the air.

4- Saint Croix Island International Historic Site

Saint Croix is in the small town of Calais in Eastern Maine, about 90 miles (145 km) east of Bangor.

This 28-acre park showcases the relationship between early French settlers and Native Americans.

In 1604, Pierre Gugua and Sieur de Mons led a group of 79 French explorers accompanied by Samuel Champlain to an island in the Saint Croix River.

They intended to take control of the territory and profit from trades with the local Indian tribes.

Unfortunately, the winter of 1604-1605 on Saint Croix Island was harsh, killing nearly half of the men on the French expedition.

When spring arrived and the health of the survivors improved, they abandoned their settlement and relocated to a more favourable spot, establishing the settlement of Port Royal in the Annapolis Basin in Nova Scotia.

Although the expedition had been disbanded by the summer, French exploration and expansion in North America continued.

Saint Croix Island became an International Historic Site in 1984 and is jointly protected by Parks Canada and the US National Park Service.

The site provides a tranquil environment where visitors can enjoy a picnic while admiring the landscape.

There’s a short interpretative trail with displays that explain the area’s history.

Exhibits, ranger-led tours and short films provide additional opportunities for visitors to learn about the region’s history.

How To Get To Saint Croix Island International Historic Site

Saint Croix Island International Historic Site is on US Route 1, about 8 miles (13 km) south of Calais, Maine. It is accessible via Route 9 from Bangor or US Route 1.

The closest airport is 103 miles (166 km) away in Bangor, where car rental services are available.

5- Roosevelt Campobello International Park

Roosevelt Campobello International Park is somewhat unusual as it’s located on Canadian soil while being jointly administered by both the US National Park Service and Parks Canada.

Roosevelt Campobello International Park is on Campobello Island is in the Bay of Fundy region in New Brunswick, 120 miles (193 km) east of Bangor.

The park pays homage to America’s 32nd President, Franklin D. Roosevelt, and Canada’s long-standing close relationship with the United States.

Franklin D. Roosevelt spent his summers as a child on Campobello Island, where he enjoyed exploring the island.

The cottage on the island where he spent his childhood summers was built in 1897 and expanded to 34 rooms; he later shared the same activities he enjoyed as a child with his wife, Eleanor, and their children.

After Roosevelt became the 32nd President of the United States in 1932, he only visited the island three more times before his death in 1945.

Although Roosevelt visited Campobello Island less frequently after becoming president, his cottage and its beautiful surroundings remained close to his heart.

On 22 January 1964, President Lyndon B. Johnson and Prime Minister Lester B. Pearson signed an agreement to establish the Roosevelt Campobello International Park.

The Franklin D. Roosevelt summer cottage and the Park’s Visitor Center are open from the last week of May to early June each year.

The natural environment and park grounds, however, are open all year.
