The ship calls in Mackinac Island, famous for its historic, summer resort and horse-drawn carriage lifestyle, en route to Canadian waters. Lynn explores the forested and rocky shoreline of North America’s “Inland Seas” via zodiac and kayak, dives under the surface of the water via sub, and delves into indigenous and fur trader history in Thunder Bay, Ontario.
