The Mill Cove Environmental Area is located near U.S. Route 15—soon to be designated Interstate 99—between Tioga and Mansfield, Pennsylvania, just north of U.S. 6. Mill Cove is on the Mill Creek arm of the Tioga Lake. Gated access is provided via Mill Creek Road.
Most of the Mill Cove Environmental Area is wooded. Several acres are cleared to accommodate primitive tent camping and other group activities. A driveway provides access through the site along Mill Creek.
