Thing to Do
Stargazing on Cadillac Mountain (Vehicle Access Limited)
Vehicle access to the summit of Cadillac Mountain at night is limited to a few months each fall and spring. The Park Loop Road is closed for winter, typically Dec 1-Apr 14. From May into October, daytime access is managed by a Vehicle Reservation System and the road closes each night at 10 pm. Overnight parking is prohibited.
Vehicle reservations are not required to hike or bike to the summit, however. Always bring flashlights or bike lights for night excursions.
Once at the summit, enjoy spectacular views of the stars as you carefully walk along the Cadillac Summit Loop. Bar Harbor, Frenchman Bay, and the Cranberry Islands can also be seen from the trail.
Cadillac Mountain serves as a good location for night sky photography with paved parking areas to provide stable surfaces for tripods. Lights from surrounding towns and vehicles may effect photos.
