Acadia National Park
Acadia is one of the smaller national parks in the country, yet it attracts nearly 3 million visitors per year. It is important that those who do visit and explore this wonderful park follow some basic guidelines in order to keep the park as clean, natural, and undisturbed as possible. Please review the Leave No Trace principles if you're planning a trip, and remember them while you are having a great vacation. Help keep Acadia the way it should be.
Originally designated as Sieur de Monts National Monument in 1916 by presidential proclamation, 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, along with some adjacent lands, was ravaged by fire.
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 and 70 degrees F. Wear light-colored clothing, long sleeve shirts, and long pants for protection. Annual rainfall is 48 inches.
Summer daytime temperatures range from 45 to 90 degrees F. Evenings are cooler. Dressing in layers is advisable for any boating or hiking activities. Ocean water temperatures range from 50 to 60 degrees F. Lake water temperatures range from 55 to 70 degrees F.
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 inches of snow annually. For the latest in weather information, call the local weather phone line at 207-667-8910 or call the park at 207-288-3338.

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 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. Cyclists will be happy to note that the Park Loop Road appears to have been recently re-paved (as of August 2008), making for a very smooth, pleasant ride. Bikes can be rented in Bar Harbor.
Acadia is a great place to birdwatch, with many species calling the park home.

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)

- 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.
