Bald Mountain State Recreation Area is a 4,637-acre (1,877 ha) state park located near Lake Orion, Michigan off M-24. It consists of some of the most rugged terrain in southeastern Michigan. The recreation area is composed of a North Unit and a South Unit, which are not contiguous. The South Unit itself includes two parts separated by M-24, but the section west of M-24 has no recreational facilities or trails and is primarily undeveloped forest and grassy plains segmented by a few through-roads.
