The river begins at an unnamed lake in geographic Fabbro Township.[2] It heads southwest through Sixpack Lake and then under Ontario Highway 546, from which point the highway follows the river valley, where it takes in the left tributary Sister River and the right tributary Kindiogami River. It loops back and forth under the highway, continues southwest, takes in the left tributary Boland River and right tributary West Little White River, passes under Ontario Highway 554, and reaches its mouth at the Mississagi River at geographic Wells Township[3] southeast of the community Wharncliffe. The Mississagi River flows to the North Channel on Lake Huron.
The Little White River Provincial Park is a waterway park that protects a 100 kilometres (62 mi) long section of the river and its banks, from approximately the northern terminus of Secondary Highway 639 to its confluence with the Mississagi River. Additionally it includes the entire West Little White River and its headwater lakes (such as Pointer, Finn, Town Line, Robb, Elbow, Kirkpatrick, White Bear, and Endikai Lakes), as well as Raven Lake Uplands that stretches to the Wakomata portion of the Mississagi River Provincial Park. It was established in 2002 and provides canoe camping and fishing opportunities.[5][6][7]
Features in the park include wetlands, oxbow sloughs, and floodplain swamps with stands of silver maple, black ash, and white elm. The Raven Lake natural heritage area contains bedrock cliff faces, upland rock barrens, deep gorges, ravines, convoluted linear wetlands, and significant stands of white pine growing on the glacier-scoured hills. The park forms a natural corridor between several natural heritage areas, such as the Mississagi River Provincial Park, the Kirkpatrick Lake enhanced management area, and the Endekai Perched Delta enhanced management area.[6]
It is a non-operating park, meaning that there are no facilities or services.[5]
