This is part of the falls at Eau Claire Gorge, on the north side of Algonquin Park, Ontario, just past the park boundary. The falls are quite big and the gorge is steep, so you can't get too close, but the trail is a nice walk and the overlook is a nice view.

I actually don't know the name of these falls. I think they would be called Mad Brook Falls, since that is approximately where this was and google maps is showing that brook name. I just found them by accident while exploring Vermont's back roads in the fall. It's a stitched panorama and is about 115 megapixels, so it's ready to be printed large!
