Advance Reservations to Visit Cadillac Mountain
Reservations are not required for most of the park , but if you want to drive to the lookout—the summit of Cadillac Mountain — reservations are required from May
25 through October 22 .
- Vehicle reservations are $6 and are sold in advance online at www.recreation.gov/timed-entry/arcadia . They cannot be purchased in the park.
- 30 percent of vehicle reservations are made available 90 days prior to the date. The remaining 70 percent will be released two days before – at 10 a.m. ET.
- Print or save a digital copy of the vehicle reservation with the confirmation code scanned to verify the reservation. Note that internet connections at the park are unreliable.
- Visitors must have a park admission ticket in addition to purchasing a Cadillac Summit Road vehicle reservation to enter the park. Park tickets are available at the park or online at www.recreation.gov/sitepass .
You can bypass the reservation and reach the summit in a much more comfortable way by climbing it on foot. If you choose to do the South Ridge of Cadillac Mountain Trail, a 7.4-mile loop hike through coniferous forests with beautiful views of Frenchman Bay and the Porcupine Islands awaits you.
This hike ( www.nationalparkstraveler.org) takes you through cool coniferous forests and up the mountain’s granite shoulders with great views of the Bay and Gulf of Maine. Although park officials class this route as “strenuous,” it’s not all that difficult if you’re not attempting to scale the summit. Once past the forest there are large granite expanses to sit and have a picnic on for a while and of course enjoy the stunning views.
