Wetzel State Recreation Area is an undeveloped protected area in Macomb County, Michigan, spanning about 900 acres. Managed as a recreation area rather than a built park, it remains largely in a natural state. People use the land for hiking, cross-country skiing, hunting, snowmobiling, and radio-controlled flying. Its importance comes from preserving a sizable open tract in a suburban part of southeastern Michigan, where outdoor recreation relies more on the character of the land than on facilities or major development.
