The William Field Memorial State Park Trail, more commonly known as the Hart-Montague Trail, is a linear state park that runs 22.7 miles from Hart, MI to Montague, MI. The state of Michigan has more "rails to trails" trails than any other state, and the Hart-Montague Trail became the first paved rail trail in the state in 1989. The southern terminus is adjacent to the end of Spring Street in Montague where there is a parking lot.
