A Cadillac sunrise plan falls apart before dawn when the reservation window is missed; how to get Cadillac Mountain sunrise tickets comes down to two timed releases on Recreation.gov. The reservation is for driving Cadillac Summit Road in Acadia National Park, not for standing on the mountain, and it is separate from the park entrance pass.
For 2026, vehicle reservations are required to drive Cadillac Summit Road from May 20 through October 25. Sunrise slots are the hardest to land because the entry window is limited, the summit parking is limited, and the earliest release often disappears within minutes in peak summer.
If a sunrise reservation matters to your trip, plan around the two-day release. Only 30 percent of sunrise reservations are released 90 days ahead, while 70 percent are released at 10 am ET two days before the reservation date.

How Do Cadillac Mountain Sunrise Tickets Work?
Cadillac Mountain sunrise tickets are timed vehicle reservations for Cadillac Summit Road. A reservation lets one vehicle enter during a 90-minute sunrise window, but it does not hold a named parking space.
The sunrise reservation covers the road access window only. Every vehicle still needs an Acadia National Park entrance pass displayed through the windshield, and cell service can be weak near the check station, so a screenshot or printed QR code is safer than relying on the app loading at 4 am.
Cadillac Summit Road is a narrow, winding road to the 1,530-foot summit. Parking is only allowed in marked spaces, RVs and trailers are not allowed, and vehicles longer than 21 feet can be denied entry even with a reservation.
Getting Cadillac Mountain Sunrise Reservations: What Opens When
Cadillac Mountain sunrise reservations open in two batches, and the second batch is the one most travelers should target. The 90-day release gives planners a shot early, but the two-day release has more inventory.
- 90 days ahead: 30 percent of sunrise and daytime reservations open at 10 am ET.
- Two days ahead: 70 percent of sunrise and daytime reservations open at 10 am ET.
- Reservation limit: one sunrise reservation per vehicle every seven days.
- Entry window: sunrise reservations have a 90-minute arrival window.
- Re-entry: the reservation does not allow a second drive up later that day.
Set an alarm for 9:55 am ET, sign in before the release time, and have your date already selected. The sunrise window in June can start around 4 am, so the booking screen is not the place to decide whether your group can handle the wake-up time.
| Ticket Or Access Type | What It Covers | Current Cost Rule |
|---|---|---|
| Sunrise Vehicle Reservation | Timed entry to Cadillac Summit Road for the sunrise window | $6 per vehicle reservation |
| Daytime Vehicle Reservation | Timed entry after sunrise for a shorter arrival window | $6 per vehicle reservation |
| Acadia Entrance Pass | Required year-round in addition to the Cadillac reservation | Separate pass; cost depends on pass type |
| Private Vehicle | One car, SUV, van, or rental vehicle under the size limit | One Cadillac reservation covers the vehicle |
| Motorcycle, Scooter, Or Moped | Road access for each motorized two-wheel vehicle | Each vehicle needs its own reservation |
| Foot Or Bicycle Access | Access to Cadillac Mountain without driving the summit road | No Cadillac vehicle reservation required |
| Taxi Access | Passenger arrival by taxi rather than private car | No Cadillac vehicle reservation required for the passenger |
| RV, Trailer, Or Over-21-Foot Vehicle | Oversized vehicle access to Cadillac Summit Road | Not allowed, even with a reservation |

Step-By-Step Booking On Recreation.gov
The safest booking path is to use Recreation.gov before the release time and save the confirmation before entering Acadia. The park does not sell Cadillac Summit Road vehicle reservations at the gate.
- Create or sign in to your Recreation.gov account before 10 am ET.
- Search for Cadillac Summit Road Vehicle Reservations.
- Select Cadillac Summit Road – Sunrise, not daytime.
- Choose the date that matches your Acadia plan.
- Refresh right at 10 am ET if the release has not appeared.
- Check out fast once a slot appears in your cart.
- Save the confirmation QR code as a screenshot and print it if you can.
A park entrance pass can also be handled through Recreation.gov, but it is a different item. The common mistake is buying only the entrance pass and arriving without the Cadillac road reservation.
What Should You Do If Sunrise Tickets Sell Out?
Sold-out sunrise reservations do not end the Cadillac Mountain plan. A daytime reservation, a hike, a bike approach, or a different sunrise spot can still work.
Daytime reservations are easier to get and still give you the summit views without the pre-dawn crowd. For a sunrise feel without the vehicle reservation, many travelers use Ocean Drive pullouts, Sand Beach, or other east-facing Acadia viewpoints, then drive Cadillac later with a daytime slot.
Hiking is another option, but only for travelers who are prepared for darkness, cold wind, and an early start. The North Ridge Trail and South Ridge Trail are real hikes, not shortcuts from a parking lot, and a headlamp is non-negotiable for pre-dawn movement.
Where To Stay For The Earliest Start
Bar Harbor is the easiest base for a Cadillac Mountain sunrise because the drive to the summit road entrance is short. Staying farther out can work, but every extra mile matters when your entry window starts before breakfast.
Choose lodging around Bar Harbor, Hulls Cove, or the east side of Mount Desert Island if sunrise is the anchor of the trip. Southwest Harbor is quieter, but it adds driving time in the dark and makes a missed alarm harder to recover from.
For early-morning logistics, compare Bar Harbor-area stays on a map before locking in the sunrise date:
Small Details That Make The Morning Easier
A Cadillac Mountain sunrise works best when the boring prep is finished the night before. The summit can feel much colder than Bar Harbor before dawn, and the parking area can fill within the reservation window.
- Pack a warm layer, even in summer.
- Bring a headlamp or small flashlight for walking from the parking area.
- Save the reservation QR code offline.
- Leave earlier than the map app suggests; the check station can back up.
- Use the restroom before driving up if your group needs extra time.
- Do not stop outside marked spaces along the road.
Sunrise times shift from very early summer mornings to later October mornings. Mid-June can mean arriving around 4 am, while mid-October gives travelers a more forgiving pre-dawn start.
Pick The Right Backup Before You Book
The strongest plan is to try for the 90-day release, try again two days ahead, and already know your backup if both releases sell out. Sunrise is worth the effort, but the trip should not depend on one checkout screen.
Use this decision list before you commit your Acadia schedule:
- For the classic sunrise: book Cadillac Summit Road – Sunrise at the 90-day or two-day release.
- For fewer booking nerves: choose a daytime Cadillac reservation and watch sunrise from the coast.
- For hikers: use a summit trail only if your group is comfortable hiking in darkness.
- For families: favor a daytime slot if a 3 am wake-up will ruin the next day.
- For fall trips: October sunrise is later, but demand can still spike during foliage weekends.
The cleanest move is simple: be logged in at 10 am ET two days before your target date, grab the sunrise slot if it appears, and keep a daytime Cadillac reservation or coastal sunrise backup ready.
