Frequently asked
Is tonight good for stargazing at Katahdin Woods?

What makes Katahdin Woods good for astrophotography?
Katahdin Woods and Waters National Monument was designated an International Dark Sky Sanctuary in 2020, the first in Maine and New England and the first on the eastern seaboard. It holds Bortle Class 1 to 2 conditions, the darkest skies east of the Mississippi River. The monument covers 87,500 acres of the north Maine woods, adjacent to Baxter State Park and the 100-Mile Wilderness section of the Appalachian Trail, creating an enormous contiguous dark landscape. The East Branch of the Penobscot River and its tributaries provide water reflections for foreground photography. The Loop Road Overlook is the primary viewing area and the location of the annual Stars Over Katahdin event each September. Cell service is essentially nonexistent inside the monument.
When is the Milky Way visible at Katahdin Woods?
The galactic core is visible from late April through September. The annual Stars Over Katahdin event in late September celebrates the monument's dark sky designation with telescopes and ranger programs. The northern Maine latitude also makes this a productive aurora viewing location, particularly in fall and winter. Bug season from late May through July is intense in the north Maine woods and worth planning around for extended night sessions outdoors.
