Waterfalls, fossils, potholes, underground stream outlets, the nests of ravens and rare black swifts, unexpectedly lush plant life and the startling effects of frost action - these are just some of the wonders of Maligne Canyon. Some geologists speculate that parts of the canyon were originally deep caves that have since been uncovered by glacial scraping and water erosion.

Parks Canada has developed a self-guided interpretative trail along the canyon with signs describing the geological history of the area.
