Cadillac Mountain Star Party

September 8, 2018 @ 8:00 pm - 11:00 pm

Reservations for the Cadillac Star Party are sold out. Only ticket holders will be allowed to attend this event. If you weren’t able to get a reservation, plan to join us at one of our other star parties on Thursday at Sand Beach or Friday at Seawall! Check the schedule for more details. 


The Cadillac Mountain Star Party will take place from 8 to 11 pm on Saturday, September 8. Participants must reserve – in advance – a parking space at Mount Desert Island High School for the event and ride a shuttle to Cadillac Mountain.

Those with reservations are invited to drop in at any time during the ongoing program to visit with more than 50 volunteer astronomers and park rangers who will describe constellations and other night sky features visible with the naked eye and telescopes. The best star viewing time will be after 9 pm. Participants are free to stroll the summit and spend as much time as they like at the star party.

Park at MDI High School for shuttle service beginning at 7:30 pm. Parking for the event is only available at Mount Desert Island High School (1081 Eagle Lake Road, Bar Harbor) by ticketed reservation. Limited reservations are available on a first-come, first served basis for $5.00 per vehicle. Reservations are nonrefundable if the event is canceled for any reason or you are unable to attend. No oversized vehicles, including school buses, motor coaches, and vehicles with trailers, will be able to park at the high school.

Parking on Eagle Lake Road will be prohibited. Parking at the Cadillac Mountain summit is only available for vehicles with people with disabilities (no reservations required). Cadillac Mountain Road will be closed to all other vehicles, pedestrians, and bicyclists at 6:45 pm.

Starting at 7:30 pm, the shuttle will run continuously between Mount Desert Island High School and Cadillac Mountain. The line for boarding the shuttle will form in the high school gym, and restrooms will be available. The last shuttle will depart Mount Desert Island High School at 9:30 pm and the last shuttle will depart Cadillac Mountain at 11:15 pm. Shuttle riders should plan on approximately 20 minutes to travel to summit or back to high school. Please note that pets, coolers, and folding chairs are not allowed since space on the shuttle is very limited.

Visitors are encouraged to dress warmly and minimize flashlight use to preserve night vision. If available, visitors should use a red night vision flashlight or cover a standard flashlight with red cellophane. The Summit Center gift shop and restrooms at the top of Cadillac Mountain will be open during the event.
