All visitors must use care. Drinking water is not yet available. The summer water temperature of Lake Superior remains steady at 46 to 48 degrees, even in shallow bays. Prolonged exposure to these temperatures can lead to hypothermia. All visitors should be prepared to spend at least one extra day on the island and leave a travel plan with someone on shore.
Visitors can get to the island via passenger ferry or private watercraft.
The ferry departs from Grand Island Landing on the mainland, located on M-28, about 4 miles west of the blinking light. Look for the Grand Island NRA signs. Weekly, monthly and seasonal passes are also available. Please respect the owners' privacy. Grand Island is closed to rock climbing and rappelling as the cliffs are sandstone.
