From fall foliage to clear night skies, Bar Harbor looks its best when the temperatures begin to fall.

US News Travel claims that September through October is the best time to visit Bar Harbor, and it’s no wonder. With the kids back to school and the nights getting chillier, tourism drops by almost half when the fall rolls in. That means no more crowds coveting popular Acadia National Park trails, as well streets of downtown Bar Harbor. It’s also the best time to check out some Downeast foliage and take in the Milky Way without the summer haze.

Activities & Attractions

Under the Stars Boat Cruise

Seek Starry Skies & Storytelling

Held in partnership with Bar Harbor Whale Watch, the Abbe Museum offers a special Under the Stars Boat Cruise every evening from September 25 to 28 during the Acadia Night Sky Festival. Departing at 7 p.m., the 130-foot catamaran Atlanticat cruises among the islands in Frenchman Bay, while John Bear Mitchell, University of Maine professor of Wabanaki and Multicultural studies, shares Maine native stories about the relationship to the night sky and naturalist Zack Klyver provides a short presentation on celestial navigation.

Take Advantage of Newly Opened Trails

While Acadia’s 155 miles of trails are beautiful regardless of the time of year, casual hikers tend to forget the benefits of hiking in cooler weather. For one, the amount of people sharing the trails plummets, and, secondly, you get access to some additional trails that close down in the spring and summer seasons on account of nesting and fledgling peregrine falcons. Since these birds start migrating in August (you can see them soaring overhead yourself during the annual HawkWatch program), you can expect the Precipice Trail and Jordan and the Valley Cove cliffs to open back up to hikers.

Maximize Your Leaf-Peeping Opportunities

Bar Harbor’s window of peak fall colors falls mid-September to mid-October each year. You can stay abreast of the conditions by keeping an eye tuned to Maine’s official foliage tracker. To come back with awe-inspiring Instagram photos of the foliage against Acadia’s rocky coast, sign up for one of the many photo tours in the area that take place in October like Acadia Images’ day-long tours or Tony Sweet’s four-day workshop from October 14 to 18.

Soak Up a Chilly Evening

There are few things better – especially after spending a chilly afternoon checking out the foliage or hiking Acadia – than warming up in a private hot tub. Each of the oceanfront Boathouse Suites at the Harborside Hotel come equipped with a private rooftop hot tub that overlooks Frenchman Bay.
