After years of working with community members, park advocates and others, Acadia finalized an annual seasonal vehicle reservation system at Cadillac Summit Road.

Know Before You Go

• Advanced Vehicle reservations are required to drive to the top of Cadillac Mountain’s Summit Road between May 21 - October 26, 2025.

• The vehicle reservation costs $6

• Hiking or biking to the top of Cadillac Mountain is free, no reservation required.

• There is a separate $35-per-car park entrance fee, which provides access to the park for 7 days.

• The Island Explorer Shuttle does NOT reach Cadillac Summit Road.

• Visitors can select either a Sunrise vehicle reservation with a 90-minute entry window, or a Daytime vehicle reservation, with a 30-minute entry window.

• If your chosen date is sold out, please note that 30% of vehicle reservations are made available 90 days ahead of each date, and 70% of reservations for each day are held back until 10am EST, two days prior. This is to help facilitate last-minute trips but be warned that demand is high for these reservations and the supply sells out quickly.

• Pro tip: Download and print or save to your phone your reservation ticket PDF with your QR code, before you enter the park. Cell phone service is unreliable in the park, and a ranger must scan your reservation QR code to access Cadillac Summit Road.

• Note: the reservations provide a timed entry, but there is no required departure time until the park closes at 10pm EST.
