    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 ↗

    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 ↗

    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.

    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.

    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.
