The island lies between Lake George and Lake Nicolet, and to the north of Neebish Island and St. Joseph Island. Pine Island is just east of its southern tip. Vehicle access to the island is via a ferry service at its northwestern tip, connecting east of Sault Ste. Marie, Michigan. The island was part of the Canada–United States border dispute settled by the Webster–Ashburton Treaty, and affirmed to be part of the United States when the treaty was signed August 9, 1842. In 1945 Sugar Island was nominated as a possible location for the headquarters of the United Nations. The island has large undeveloped areas, and both the Bay Mills Indian Community and the Sault Tribe of Chippewa Indians have interests on the island. The Sault Tribe consider it to be part of their ancestral homelands. The University of Michigan Biological Station operates the Chase Osborn Preserve, a  tract near the southern tip of the island. The Preserve is named for Chase Osborn, an island resident who had been the Governor of Michigan. Prominent residents
