The Straits of Mackinac has been a navigation route from time immemorial. With the passage of time, the size and number of vessels traversing the Great Lakes increased exponentially. Natural hazards including storms, shoals, fog and ice floes presented on-going threats to early mariners. Lighthouses were built and used as beacons to facilitate maritime trade. The Straits has over a dozen lights strategically located on and around the islands, reefs and shores of northern Lakes Michigan and Huron. Many of these lights are in operation today while others stand as memorials to the courage of generations past. For an up close-up and personal view of many of the lighthouses in the Straits Area, enjoy a lighthouse cruise during the summer months; you have your choice of a Westbound cruise or an Eastbound cruise or if you have time, enjoy both!
