This park preserves the nationally significant Rapids Reach of the Athabasca River upstream from Ft. McMurray. Forested valley slopes are critical moose wintering range. Important fish species in this stretch of the river include walleye, lake whitefish, mountain whitefish, Arctic grayling, pike and goldeye. The Rapids Reach is very scenic, with numerous rapids, rock outcrops and slump blocks. The river is deeply incised for the entire length of the park, in places exceeding 150 metres. The incised meanders that have eroded into the bedrock are a significant feature of the park.
