The legend behind the name Sault-à-la-Puce has it that two Québec City men drowned here in 1640 while hunting on the islands. A man by the name of La Puce was sent to confirm their disappearance, hence the curious name. George Heriot immortalized the waterfall and its river in 1812, as he criss-crossed the Côte-de-Beaupré region.
