A park ranger shares sea life with children at a summer program. (NPS Photo) Acadia offers a variety of activities throughout the year. During the summer, spring, and fall, 45 miles of carriage roads are ideal for walking, hiking and biking. In addition, over 115 miles of hiking trails offer spectacular ocean and woodland views. Trails range from easy to strenuous. By automobile, visitors can drive the 20-mile Park Loop Road and take the 3.5-mile spur road to Cadillac Mountain, both of which include views of some of the most dramatic scenery along the eastern seaboard.
Most of the Park Loop Road is closed during the winter. A variety of ranger-led programs, including bird walks, boat cruises, evening slide programs, mountain hikes, stargazing, short talks, and nature walks, are available from late May to mid-October. Other summer activities include fishing, boating, carriage rides, and wildlife viewing. During the winter, the carriage roads and the closed portions of the Park Loop Road are ideal for cross-country skiing and snowshoeing.
