    Cruise ship season

    1 May – 31 OctCruise seasonCrowded

    Ships tender into the harbour from May, and the heaviest calls land in September and October with the leaf cruises. The town's thousand-passenger daily cap survived court only for July and August, so the autumn days are the crowded ones. Source ↗

  • Opening

    The CAT ferry to Nova Scotia

    14 May – 14 Oct · usuallySummer season opensBook early

    The fast ferry to Yarmouth runs from mid-May to mid-October and takes three and a half hours across the Gulf of Maine. Outside those dates the only way to Nova Scotia is a very long drive. Source ↗

  • Holiday

    Memorial Day weekend

    23–25 MayNational holidayCrowdedBook early

    Memorial Day, the last Monday of May, opens the summer travel season: over the long weekend campsites and lodging book out, roads are slow, and parking at the most popular spots fills early in the day. Source ↗

  • Nature

    Lobster season

    15 Jun – 15 Dec · usuallyForaging season

    Most of the Maine catch comes ashore between the summer shed and the end of autumn, and prices at the pounds follow the boats. Late summer soft-shell lobster is cheaper and sweeter than the hard-shell you get flown out of state.

    1 Jul – 31 AugSchool holidaysCrowdedBook early

    A town of five thousand hosting several million park visitors a year does most of it now. Rooms are booked months out, and the Island Explorer bus is quicker than looking for a parking space downtown.

  • Holiday

    Independence Day

    3–5 JulNational holidayCrowdedClosures

    The Fourth of July is a federal holiday: banks and government offices close, fireworks draw large crowds to parks and waterfronts after dark, and roads and flights are busy over the long weekend. Claim a viewing spot early. Source ↗

    Labor Day, the first Monday of September, is the last big getaway of summer: the long weekend books out campsites and lodging and fills parking early, and families thin out quickly once it has passed. Source ↗

    Mount Desert Island turns through the first half of October, later than inland Maine because the sea holds its heat. The colour and the leaf-peeping cruise calls arrive in the same fortnight.
