Gros Cap Reefs Light is located near Sault Ste. Marie in Ontario’s Algoma Country. This 59 foot (18 m) tall light tower marks the beginning of the St. Marys River from Lake Superior and is adjacent to Point Iroquois in Michigan. It is in shallow water on southwest edge of Gros Cap Reef. It was first lit in 1953 and has a three story light keepers dwelling with skeletal tower.
Gros Cap is visible from Point Iroquois with binoculars, though it is best seen by from the water by boat.
