It has an effigy mound in the shape of a snake, constructed as an earthwork nearly 2,000 years ago by indigenous peoples of the Hopewell culture.

Formerly a Provincial Park, the government returned the site to the Hiawatha First Nation as a historically significant burial ground for the Indigenous people.

In addition to the mounds and campgrounds, the park also has a groomed beach for swimming and several kilometers of walking and biking trails.
