Fiborn Karst Preserve
Naubinway, Mackinac County
Hiking Trails
Two self-guided trails offer visitors a look at the geology and history of the area. The Sinkhole Trail is a short loop past many shallow sinkholes and a creek disappearing below ground. The 1.5-mile Barbara Ann Patrie Memorial Trail travels along the edge of the quarry, through second-growth forest and past sinks, and Fiborn Pond.
