Thompson's Harbor State Park is a remote and largely undeveloped public recreation area on Lake Huron covering in Presque Isle County, Michigan. The state park's 7.5miles of pristine shoreline encompass a varying terrain of second growth forest, limestone cobble beaches, and deep sand dunes. The park's flora and fauna include a large population of dwarf lake iris as well as more than one hundred bird species, coyotes, deer, and possibly black bear. The park offers 6miles of trails for hikers and cross-country skiers, rustic cabins, and opportunities for sea kayaking. The park was designated a Michigan "dark sky preserve" in 2016.
