John A. Latsch State Park State Park spans 408,712 acres in Minnesota — a designated recreation destination with the full set of facilities the state park system provides. The park is not lake-dense — 2 lakes nearby in our dataset — but Halfmoon Lake (D) is the standout among them.
State parks pair well with the LakeGrade dataset: the park itself usually has interpretive signage explaining the local lake system, but the per-lake grade tells you which actual lake in the system to head to.
