The Deschênes Rapids are in the Ottawa River at the community of Deschênes near Aylmer, Québec. This is directly across the river from Britannia at the yacht club and the filtration plant near Mud Lake. There are some ruins in the rapids between the Quebec shoreline and the large island. These ruins are a popular photographic spot as well as a place for whitewater kayaking (beside the ruins, not through them since there are apparently dangerous hazards including metal rebar). This KAP outing (kite aerial photography) took place from the shoreline near the ruins on the Quebec side of the river.
