The Agawa Canyon is a shallow canyon located deep in the sparsely populated Algoma District in Northeastern Ontario, Canada. It was created 1.2 billion years ago by faulting along the Canadian Shield and then enlarged by the erosive action of the Agawa River. The Agawa Canyon Wilderness Park is only accessible by hiking trail or the Algoma Central Railway, and is located 114 miles (183 km) by rail north west of Sault Ste.
