The park is named after Pierre de Troyes who may have portaged across Long Point during his Hudson Bay expedition in 1686.

It was formerly a waterway-class park and included the public lands along the Abitibi River all the way to Iroquois Falls.

[3] Notable features of the park include coniferous forest, swamps, eskers, kettle basins, and waterfowl nesting areas.

One site is the portage trail that was likely used by indigenous people and fur traders, as well as by de Troyes' expedition to Hudson Bay in 1686.

The other site is that of "The Lonely Tombstone", which marks the grave of a voyageur who shot himself while taking his gun out of his canoe in 1865.
