Stargazing on Cadillac Mountain

Milky way over a mountain summit and trees

Gaze in awe at Acadia’s night sky from the highest mountain on the eastern seaboard. Because this is a popular location, advance reservations are required to drive up Cadillac Mountain. You do not need reservations to hike or bike to the summit; always bring flashlights or bike lights for night excursions.

Enjoy spectacular views of the stars, the Milky Way, and more from the comfort of your car. If you want to move away from the parking lots and other vehicles, 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. Photos may however be impacted by the lights coming from surrounding towns and vehicles in the parking lot.
