Potholes Provincial Nature Reserve

Nestled in the boreal forest 55 kilometres east of Wawa on Highway 101, Potholes is a remarkable geological site. The Kinniwabi River was shaped
by glacial action 10,000 years ago. Large holes called “potholes” were naturally drilled into the stream bed by rock fragments powered by glacial meltwaters. The water still flows through these potholes and provides a site of great natural beauty and significant geological interest. A five minute walk along a gravelled pathway takes the visitor to the potholes.
