This nature reserve east of Wawa gets its name from glacial potholes and troughs scooped out of bedrock forming the riverbed of the Kiniwabi River. Stop for a picnic, soak up the scenery or follow a short interpretive trail for a close look at the potholes, and sedges and forbs (flowering plants) growing along the riverbank.

Bringing your own supply of firewood to the park this summer? Please read this.
