Sleeping Bear Dunes National Lakeshore occupies a long stretch of northwestern Michigan’s Lower Peninsula along Lake Michigan, protecting towering dunes, sandy beaches, forests, inland lakes, and steep coastal bluffs. The protected area extends across the Leelanau and Benzie county region and includes the Manitou Islands offshore. Its most recognizable feature is the Sleeping Bear Dune, which rises high above Lake Michigan and the surrounding landscape.

Adjoining the idyllic farm of the McGill family are miles of beaches, tussock grass, and wildflower meadows, the nesting grounds of hundreds of Magellanic and gentoo penguins, upland and kelp geese, crested and flightless steamer ducks, tussock birds, and night herons. After viewing the birds, take a spot of tea in Mrs. McGill's kitchen.
