Significant features of the park include Nipigon Moraine remnant, unconsolidated transverse ridges, provincially rare smooth woodsia (Woodsia glabella), and diabase cliffs and talus slopes. The forests within the park are mostly boreal mixedwood that are generally more species-rich than areas to the east and west. The park also plays an important role as a natural wildlife corridor between the Lake Nipigon Basin and the shoreline of Lake Superior, in particular for woodland caribou.
