Island Lake lies on the shores of Upper Island Lake and Lower Island Lake; the Upper Island Lake Dam controls the flow from the former to the latter, and the waters flow via the Root River to the St. Mary's River.
Island Lake—both Upper and Lower, is home to many cottages and private residences; only Lower Island Lake has public beach access and public parking via Ontario Highway 556. Cameron Road, Old Mill Road, Brooks Road, and Arbour Road are all accessible via 556; the names of many area roads originate from last names of families who were the first to purchase land and build property, some of which still remain in the area, hence "Cameron Road" or "Brooks Road".

Island Lake and surrounding area is regionally famous for spectacular fall colours due to the abundance of forestry and mountains. Telecommunication services in the area are offered by major Canadian company's such as Bell, Rogers, Telus, and other smaller providers; the area has a volunteer fire service and is regularly patrolled by the Ontario Provincial Police.
