The Acadia Cadillac Mountain Reservation System 2024: All You Need to Know

The tallest mountain in Acadia National Park is Cadillac Mountain.  The drive up Cadillac Mountain is one of the most popular things to do in Acadia National Park – views from the summit are spectacular and this is a popular place to watch the sunrise. 

In order to eliminate congestion on the Cadillac Summit Road and the parking area at the top, the National Park Service has introduced a reservation system for the road. 

The reservation system can be a little complicated.  I am a national park expert and I have written this detailed guide to the Cadillac Summit Road reservations system to make your planning easier and help ensure you can get to the summit to enjoy the views.

Type of entry tickets/ reservations 

Reservations will be required for vehicle access to Cadillac Summit Road that goes to the top of Cadillac Mountain.  

There are two types of timed entry Cadillac Summit Road reservation periods: 

1) Sunrise reservations

This applies for entry in a 90-minute window as follows (times change with the sunrise times):   

  • May 22 – July:  4:00 am – 5:30 am 
  • August: 4:30 am – 6:00 am 
  • September: 5:00 am – 6:30 am 
  • October 1-15: 5:30 am – 7:00 am
  • October 16-27: 6:00 am – 7:30 am

You can enter at any time within this 90-minute timeslot. Sunrise times range from 4:45 am in mid-June to 6:15 am in mid-October.

There is a limit of one vehicle reservation within a seven-day period. 

2) Daytime reservations

You reserve a time slot that gives you a 30-minute window in which to enter the road throughout daylight hours.    

Reservations are required between the following hours (varies by month): 

  • May 22 – July:  6:00 am – 8:00 pm 
  • August: 6:30 am – 7:30 pm 
  • September 1-15: 7:00 am – 7:00 pm 
  • September 16-30: 7:00 am – 6:30 pm
  • October 1-15: 7:30 am – 6:00 pm
  • October 16-27: 8:00 am – 5:30 pm

There is a limit of one vehicle reservation per day.

Some things to note

For both types of timed entry, re-entry is not permitted. 

The reservation is for timed entry only and does not include a parking reservation – or guarantee a parking space. 

Once you enter (on either reservation), you can stay as long as you like – you just need to be out by 10:00 pm when the road is closed for the night.

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

Period reservations are needed for 

The ticketed timed entry Cadillac Summit reservation system will be in place between May 22 and October 27, 2024

How to get entry tickets/ make reservations 

The tickets will be released in two different allotments: 

1) 30% of the tickets will become available at 10:00 am Eastern Time each morning 90 days in advance of each date.  

2) The remaining 70% of them will be released at 10:00 am Eastern Time two days in advance of each date. 

Entry tickets are only available online at the NPS reservation system.  They will not be available at park entrance stations, visitor centers or park offices. 

Cost of tickets/ reservations 

Tickets cost $6 per vehicle (and all its occupants). 

Note that this $6 is in addition to the park entrance fee and is not included in the national park fee.   

When is it not necessary to make a reservation for the Cadillac Summit Road? 

This reservation (and fee) is not required if you hike, ride a bicycle or take a taxi to the summit. The entry ticket is only required for private automobiles, not bicycles, taxis or hikers.  

It is also not required if you enter at night after the last time slot but before the road closes for the night (however, it will be dark with little visibility).

It is also not required for the few weeks that the road is open before and after the timed entry system is in effect (April 15 – May 21 and October 28 – November 30)

NOTE: If you miss out on a reservation, the Cadillac Mountain Shuttle is a privately run paid shuttle service to the top of Cadillac Mountain.
