Summer Island is an island in Lake Michigan, 2.5 miles (4 km) miles off the southern tip of the Garden Peninsula in the U.S. state of Michigan.[1] It can easily be seen from Fairport, on the southern end of Delta County Road 483, the locally maintained extension of M-183, but is not accessible to the public.
The island is part of the Niagara Escarpment archipelago in northwestern Lake Michigan. Its highest point is 710 feet (217 m) above sea level, and 129 feet (40 m) above the level of the lake. One of its most prominent shoreline features is Gravel Point, a northern headland that stretches toward the Garden Peninsula mainland. More than half the island is owned by the state of Michigan and administered as part of Lake Superior State Forest.
