Acadia National Park
See main listingThe crown jewel of Maine state parks sprawls across 47,000 acres of woodland, granite peaks, and rocky shores near Bar Harbor. The park stays open year-round, though services thin out dramatically between October and May. Winter visits are quieter and doable, but plan for limited food options in surrounding towns.
Hiking is the main draw. The Gorge Trail to Cadillac Mountain's summit is a serious undertaking, combining rock scrambling with elevation gain, and isn't for casual strollers. Expect multiple hours and bring your knees' sense of humor. Thunder Hole, a natural rock inlet where waves crash with a thunderous boom, is another iconic stop, though timing matters. Visit about an hour or two before high tide for the best show. On calm days, the effect fizzles, so check conditions before making the trip.
