The islands blend the exposed rocks and pines of the Canadian Shield with the hardwood forests found further south. The park can only be reached by boat and all of the islands are open to the public. Limited camping and docking facilities, trails and cabins are only available on the largest island, Beausoleil Island.[4]
Beausoleil Island is the largest island in the park and it offers island tent camping, overnight and day docking, heritage education programs, and hiking trails. Wheelchair accessible sites and reserved campsites are also available at the Cedar Spring campground on Beausoleil Island.
