The trail winds through parts of Somerset, Cambria, and Bedford Counties, cutting through Gallitzin State Forest, state game lands, and Blue Knob State Park.

The southwestern terminus of Lost Turkey Trail is at a parking lot on Pennsylvania Route 56, across the road from Babcock Picnic Area, about 10 mi southeast of Johnstown.
