The park protects the island archipelago stretching along southeastern Georgian Bay. Glaciers have divided the park into two distinct natural areas. The ragged northern islands are a rocky expanse of gnarled pines. The southern islands consist of meadows, swamps, wetlands, and forests. Visitors can view rare species of wildlife along walking trails on Beausoleil Island, the park's largest island. Recreational activities on the island include fishing, swimming, bicycling, boating, kayaking, and canoeing. Campgrounds, picnic facilities, and docking areas are available. Access to the park's islands is by boat only from Honey Harbor. The park also offers guided hikes, exhibits, slide presentations, wildlife viewing, and educational programs on the Greater Georgian Bay.
