About Lower Denison Falls
Lower Denison Falls is a remote, forested waterfall near Wawa, Ontario (approximately 19.1 miles / ~30.7 km from Wawa). It is set on a small river/stream and is best known for a rocky gorge and a series of drops rather than a single tall plunge. Flow and appearance vary seasonally (highest flows in spring). Trail access is rustic and may be unmarked in places; visitors should plan for backcountry conditions.
The Setting
Lower Denison Falls sits at 205 metres within Nimoosh Provincial Park, in the foothills of Ontario. The falls drop 3 metres.
Why This Waterfall Exists
Lower Denison Falls flows over hard metamorphic rock, primarily marble and iron formation, laid down over 2.5-3.2 billion years ago. The softer siltstone and mudstone erodes faster than the resistant marble and iron formation, creating a 9-foot drop where water plunges over the remaining ledge.
