Michigan is the only state to border Lake Michigan on both its Upper and Lower Peninsulas.

Lake Michigan borders four U.S. states: Illinois, Indiana, Wisconsin, and Michigan. However, Michigan is the only state that has shores on both the Upper and Lower Peninsulas, making it unique in its relationship with the lake. The lake’s large shoreline along Michigan offers stunning views, beaches, and access to various recreational activities, contributing significantly to the state’s tourism and economy.
