Potholes Provincial Nature Reserve

Potholes Provincial Nature Reserve is a remarkable geological site on the Kinniwabi River east of Wawa on Hwy 101. A short interpretive trail takes you through a garden-like setting in the Boreal Forest. Distinctive “potholes” in the bedrock were naturally formed by glacial meltwaters 10,000 years ago and water still flows through these potholes.

Stay for a picnic and soak up the scenery then follow a short interpretive trail that leads to the potholes, sedges and flowering plants growing along the riverbank.
