This northern Ontario park consists of winding Lake Abitibi, parts of the Abitibi and Black rivers, and a 12-kilometre peninsula extending into Lake Abitibi. Following the natural contours of the waterways, the park features coniferous forest, swamps, eskers, kettle basins, and waterfowl nesting areas. An esker is a narrow, winding ridge of gravel or sand, deposited by the melting waters under a glacier. Owing to the shallowness, muddiness and extreme wave action of Lake Abitibi, caution is advised when navigating. A guide is recommended for lake travel.
