Oak Orchard Creek at the Iroquois National Wildlife Refuge is open to paddlers from Knowlesville Road to Route 63 and is approximately 5.5 miles one way (11 miles RT). We suggest launching from Knowlesville Road, but you are also able to launch at Sour Springs Road and Route 63 (be careful for passing traffic). This waterway is not groomed regularly, so expect variable water levels and obstructions including beaver dams and downed trees as you travel through the wooded swamp.
