Standing along the shores of Lake Michigan marking the southern entrance to the Manitou Passage. In 1875 one of the first life saving stations was established by the U. S. Life Saving Service at the lighthouse. This was the last manned lighthouse on Lake Michigan, and the last Michigan lighthouse to lose its keeper after it was automated in 1982. It is a unique looking lighthouse with its red gambrel roof and green trim.
