Permits & Reservations
The Cadillac Mountain sunrise timed-entry reservation is Acadia's most competitive permit — a Recreation.gov lottery that sells out months in advance for peak summer dates. Midday visits to Cadillac do not require a reservation. The Otter Cliffs group climbing permit is the other Recreation.gov-administered permit in the park; individual climbers do not need one.
Reservation
Vehicle reservation required to drive Summit Road to the Cadillac Mountain summit during the season. Hikers on the North Ridge, Gorge Path, South Ridge, or Cadillac North Ridge trails need no reservation — this is a vehicle-only requirement.
Sunrise windows sell out weeks to months in advance. Mid-day and afternoon slots are more available. Book early for the first-sunrise season.
