Are you planning a visit to Acadia National Park? Before you get here, it's important to know the difference between an entrance pass for the whole park, and a vehicle reservation just to drive up to the summit of Cadillac Mountain. You can buy both before you leave home at Recreation.gov.
Vehicle Reservations Required for Cadillac Summit Road
Acadia is among the top ten most popular national parks in the United States, with more than 4 million visits a year. Visitation has surged almost 60 percent in a decade, leading to severe crowding at many park destinations. In 2019, the National Park Service completed a five-year process to approve a comprehensive Transportation Plan that may take a decade or longer to implement fully. Actions are decided with an adaptive management strategy that continually monitors, evaluates, and refines solutions toward best possible outcomes.
Cadillac Summit Road
Cadillac Summit Road offers a three-mile drive to the top of the highest peak in the park. Along the way, there are several scenic pullouts to enjoy the view. Parking is available in two locations at the summit, where restrooms, a gift shop, and scenic overlooks connected by paved walks can be found. There is no Island Explorer bus service on the Cadillac Summit Road. Sunrise times range from 4:45 am in mid-June to 6:15 am in mid-October.
The narrow, two-lane road winds to the 1,530-foot summit of Cadillac Mountain. Drivers should use caution when traveling the road and yield to pedestrians. Recreational vehicles and trailers are prohibited.
Paved pullouts are located along the road for short-term parking to enjoy the views. Do not cross traffic to pull out on the opposite side of the road. Parking is available at two locations at the Cadillac Summit.

Recreational vehicles, trailers, and vehicles over 21 feet long (including bike racks and hitch attachments) are prohibited on Cadillac Summit Road.
