Acadia National Park welcomes visitors 365 days per year and is never "closed."

Winter weather dictates when most visitor facilities, hiking trails, roads and activities open and close for the season. May through October is typically considered our “summer” season when most facilities and roads are open and accessible.

How Your Fees Help Acadia National Park
The fees you pay when visiting Acadia make a difference. Under the Federal Lands Recreation Enhancement Act, Acadia keeps 80 percent of all fees collected and uses that money to improve visitor services and fund critical deferred maintenance projects in the park such as:
  • Maintain and rehabilitate park carriage roads and hiking trails
  • Maintain and repair campgrounds, buildings, and picnic areas
  • Maintain and repair paved roads and parking areas
  • Improve park accessibility for visitors with disabilities
  • Operate and maintain the Island Explorer bus service
  • Provide lifeguards at Sand Beach and Echo Lake Beach
  • Provide unique interpretive programs
  • Support and maintain museum exhibits
Hulls Cove Visitor's Center
A good place to start your exploration of Acadia National Park, as its name implies, is the information center for visitors, located along Route 3 outside the island village of Hulls Cove, about eight miles beyond the Thompson Island bridge. Park your vehicle in one of the 200 available spaces, climb the 52 stairs, and head on in.
The visitor center includes staff available to answer questions, supplies of maps and copies of the park newspaper called the Beaver Log, a well-stocked bookstore, a large relief map of Mount Desert Island that helps orient visitors, a theater that shows a 15-minute video, The Gift of Acadia, on the hour and half-hour during the day, and (of course) all-important restrooms.
