A rocky portion of the coastline in Acadia National Park.

Acadia National Park is the only United States national park in New England and the easternmost national park on the mainland. It is on the coast of the Down East region of Maine, near the town of Bar Harbor.

Understand

Acadia NP encompasses more than 47,000 acres (19,000 hectares), 30,300 of which are on Mount Desert Island. 2,728 acres of the park lie on Isle au Haut and 2,266 more on the Schoodic Peninsula in Winter Harbor.

Acadia is one of the smaller national parks in the country, yet it attracts around 4 million visitors per year.

History

It was designated as Sieur de Monts National Monument in 1916 by a presidential proclamation by Woodrow Wilson. Congress renamed the park Lafayette National Park in 1919. Congress again enacted a name change in 1929 to the name we now use, Acadia National Park. It was the first NP established east of the Mississippi River.

In October 1947, Acadia and some adjacent lands were ravaged by fire.

Landscape

A quick look at any topographical map of Mount Desert Island will indicate the powerful and lasting effects of the last ice age on the island and the current landscape of Acadia. As the last glacier receded over 18,000 years ago it left behind the elongated mountains and lakes we see today. The moving ice was also the culprit behind the "bald" summits of most of the park's hilltops, scraping off vegetation and leaving the beautiful pink granite underneath.

Flora and fauna

More than 273 bird species have been identified in the park, including bald eagles, peregrine falcons, blue jays, finches, and chickadees (the Maine state bird). Mammal species include deer, squirrels, foxes, rabbits, porcupines and bats. Other species include garter snakes, the American bullfrog, and the North American red-bellied salamander.

Acadia's weather is largely a product of latitude and marine influences. On a daily and annual basis, Mount Desert Island temperatures are more moderate than those of inland Maine. The Maine coastal climate has been ranked second only to the Pacific Northwest in annual precipitation. This moisture occurs in every form at Acadia. Ice storms are regular in winter and early spring, and rain is frequent in every month. Fog is common during June, July, and August.

Spring can be foggy with temperatures ranging between 30 °F (−1 °C) and 70 °F (21 °C). Wear light-colored clothing, long sleeve shirts, and long pants for protection. Annual rainfall is 48 in (1,200 mm).

Summer daytime temperatures range from 45 °F (7 °C) to 90 °F (32 °C). Evenings are cooler. Dressing in layers is advisable for any boating or hiking activities. Ocean water temperatures range from 50 °F (10 °C) to 60 °F (16 °C). Lake water temperatures range from 55 °F (13 °C) to 70 °F (21 °C).

Fall temperatures can range from low 70s during the day to freezing during the night. Come prepared for all types of weather, from sun to fog, from downpours to flurries. Fall foliage often peaks during the first couple of weeks in October. Weather conditions over the summer, such as drought, may alter the time that the leaves peak.

In the winter, due to Acadia's coastal location, snow and weather conditions change rapidly. Temperatures vary from mid-30s to below zero. The park averages 61 in (1,500 mm) of snow annually.

Do

Land activities

There is an extensive network of carriage roads throughout Acadia National Park, which are closed to automobiles and are excellent places to ride your bicycle. The carriage roads are mostly paved with crushed stone and, therefore, are best navigated on a mountain or hybrid bicycle. Another option for cyclists is the ~20 mile (32 km) long Park Loop Road, which encircles much of the eastern portion of the park. The road is open to automobiles, but is a one-way, two-lane road for much of its length. The Park Loop Road appears to have been re-paved in 2008, making for a very smooth, pleasant ride. Bikes can be rented in Bar Harbor.

Acadia has the best day hiking in the Eastern U.S. Walking the miles of trails is one of the best ways to experience the park. Immerse yourself in the flora and fauna of the island on a number of different hikes of various environment, length, and difficulty. These trails are stunning, with high ocean views, accessible tree lines, steep precipices, stone bridges, etc.

Acadia is a great place to birdwatch, with many species calling the park home including bald eagles, peregrine falcons, great blue herons, cranes, ducks, geese, chickadees, woodpeckers, owls, orioles and blue jays can be seen in the park. For an extensive checklist and more info on birdwatching opportunities in Acadia, see the NPS's birdwatching page.

The park is one of the darkest spots on the East Coast and on a clear night stargazers can see the Milky Way in all of its glory. Drive into the park after dark, find a safe place to stop along one of the park roads or parking lots where you're not crowded in by trees or lights, get out and look up. You will not be disappointed.

Water activities

The last glacier of 18,000 years ago carved out the incredible and beautiful terrain of the park, leaving behind some of the cleanest lakes and ponds in the country. Sea kayaking tours and boat rental services are offered from numerous establishments in Bar Harbor and allow access to Mount Desert Island and other destinations.

Fishing is allowed in the park in accordance with the park regulations. While ocean fishing is open to all, fishing in freshwater lakes and ponds requires a Maine state fishing license. Licenses are required for residents aged 16 and up and non-residents 12 and up, and can be purchased at town offices and a few local shops.

Some ponds and lakes are used for drinking water and do not allow swimming; check park office for list of approved swimming locations.

• Sand Beach. Watch out for a strong undertow at this ocean beach accessible from Park Loop Road 
• Echo Lake beach. 

Tours

Those who prefer a guided experience can choose between free park tours or commercial options.

Eat

Operated by the company which holds the franchise for food and shops within Acadia National Park, the Jordan Pond House, offers acceptable but overpriced food for lunch and dinner, but is essential for afternoon "tea and popovers". The setting, with a view of The Bubbles up the pond, is delicious, the popovers hot and eggy. Reservations are a must for tea (and even then you'll probably wait 10 or 15 minutes). (2005)

Backcountry

Backcountry camping is not permitted (and strongly discouraged due to the fragile ecosystem) in Acadia National Park.

Stay safe

• It is unsafe to venture out onto Maine's coastal waters without having the necessary equipment and experience. This is true of kayaking, canoeing, sailing or any other kind of boating. The water is cold and hypothermia can set in in a short amount of time. Dense fog often rolls in very quickly as well as the occasional storm.

If you are determined to go out on your own, it would be foolish and could result in serious fines from the Coast Guard or a Marine Patrol officer to do so without every single passenger:

• wearing a PFD and/or
• having a compass and knowing how to use it and/or
• understanding how to navigate safely around other boats and water hazards

There are numerous companies on Mount Desert Island and elsewhere that offer guided sea kayak, sailing, and power boat tours.
