The Grand Traverse Bay Area is a region in Northern Michigan, known for its lakes and lakeshores, for its cherries and grapes and mushrooms, and for its boating and downhill skiing. Technically, the name refers to the shoreline bordering the West Arm and East Arm of the Grand Traverse Bay, but more generally the name is used to refer to all of Grand Traverse and Leelanau Counties and at least the northern part of Benzie County; western Antrim County, which also borders the bay, may be included as well. Traverse City makes an excellent base for exploring the Leelanau and Old Mission Peninsulas to the north, and the Sleeping Bear Dunes National Lakeshore to the west.
