Vehicle Reservations Planning Underway

Visitors to Acadia National Park will need a vehicle reservation to drive up the Cadillac Summit Road during sunrise and daylight hours for the 2021 summer season. Details about reservation dates, costs, and sales procedures are expected to be announced early in the new calendar year.

Vehicle reservations will not be required for the Sand Beach Entrance corridor in 2021, however. While this popular two-mile stretch of the Park Loop Road was included in an 18-day pilot of the reservation system last October, further implementation and planning has been postponed for this area, as well as Jordan Pond.

Factors contributing to next steps include the availability of the fare-free Island Explorer bus system, which was sidelined due to COVID-19 for all of 2020, as well as a number of significant safety, staffing, infrastructure, and connectivity concerns.

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.

  • Acadia is among the top ten most popular national parks in the United States, with more than 3.5 million visits a year. Visitation has surged almost 60 percent in a decade, leading to severe crowding at most park destinations. The National Park Service has prepared a Transportation Plan to reduce severe traffic and parking congestion so visitors can plan ahead and have a more enjoyable visit.
  • Vehicle reservations are not required for other areas of the park, and are not required for visitors who enter reservation areas by foot or bike.
  • Vehicle reservations are purchased in advance online at, and are non-refundable for any reason, including fog, cloudiness, and other weather.
  • You must have have a valid park entrance pass in addition to your vehicle reservation. The vehicle reservation fee is not discounted for annual and lifetime pass holders.
