There are no roads leading to Muskoka Mills. Follow Hwy 69/400 to Crooked Bay. Just north of Crooked Bay, take exit 174 (South Gibson Lake Rd.) Note: there is also a Gibson Lake. If you follow the Gibson River west you will see the junction with the Musquash River which gets its source from "Go Home Lake". The river (now technically the Musquash) continues into a small bay. Muskoka Mills is just at the mouth of where the Musquash empties itself in the Bay.
