Cambridge Junction Historic State Park is a historical preservation area 3 mi south of Brooklyn in Cambridge Township, Michigan, that includes Walker Tavern, a major stopping place for stagecoaches traveling between Detroit and Chicago in the early nineteenth century. The tavern is operated seasonally by the Michigan History Center. The 80-acre state park includes two additional historic structures: a reconstructed barn with artifacts and exhibits about people, travel and work in the mid-19th century, and the 1929 Hewitt House Visitors Center which focuses on early auto tourism and has displays about well-known 20th-century roadside tourist attractions in the Irish Hills. Additionally, a 1-mile hiking trail encircles the park, crossing both wetlands and forested areas.
