Northwest Michigan Ports of Call have served shippers and summer's people for over 150 years--though at first, in places like Frankfort, goods and people had to debark their schooners in small boats, and pigs and cows were simply shoved overboard to swim for shore.  This tour is filled with opportunities to experience historic boats, fishing villages, harbors and lighthouses. It starts at Ludington and works its way toward the Straits of Mackinac—but any place along this 250-mile shoreline is a good place to start.
