The Sinkhole Pathway, encircling a sinkhole area in a heavily wooded forest, provides a hike unlike any other. The area features karst topography characterized by natural limestone, where underground streams dissolve the rock into a series of large caves. These caves eventually result in sinkholes after collapsing under the weight of sand, rock or clay.

The pathway is 2.5 miles, encircles 5 sinkholes and is popular with hikers. The pathway links to the 70-mile High Country Pathway. The trailhead is 12 miles southeast of Onaway via M-33 South and Tomahawk Lake Highway. The trail can be accessed 0.1 miles down Shoepac Lake Road from Shoepac Lake State Forest Campground.

Backpacking (dispersed camping) is allowed along the pathway, as long as you are one mile away from Shoepac Lake State Forest Campground. View a map of state forests and campgrounds.
