Grand Ledge is a city in the U.S. state of Michigan. The city lies mostly within Eaton County, though a small portion extends into Clinton County to the north. The city sits above the Grand River 12.7 miles (20.4 kilometers) west of downtown Lansing. The population was 7,786 at the 2010 census. The city is named for its sandstone rock ledges that rise 40 feet (12 m) above the Grand River and are used by recreational rock climbers.

Native Americans who lived in the vicinity of the Grand River close the ledges were of Pottawatomi, Chippewa, and Ottawa ancestry. They dug clams in the river, mined coal upon the river banks, hunted for deer, turkey, fox, and bear, and fished for black bass. Their reveal for the ledges translated into English as “Big Rocks”.

Based on early records, Hugh Heward was the first white man to investigate this Place by water and stamp album his findings. His journal describes the sandstone ledges as having tall banks, some pine trees and stifling woods in the impression of the finest places realistic for making syrup, and the existence of several little islands.
In 1847 Henry Trench approved in what would highly developed become downtown Grand Ledge. After a few years he returned east. In 1850 settlers named their village Grand Ledge, and erected a publicize office. By 1869, a railroad reached the north decline of the village. In 1871, the village was incorporated by the confess of Michigan.

Grand Ledge grew as a resort area during the 1870s, spurred by the railroad access. John Burtch founded Seven Islands Resort in 1872, with the Dolly Varden steamer and a little inn on Second Island. Several wells were drilled, and the mineral-laden water they produced was touted for its curative property. In 1877 S.M. Hewings purchased the Seven Islands Resort, and in 1878 he built the Island House Hotel on Second Island. In 1880 Julian Scott Mudge purchased the Seven Islands Resort. To shorten the risk of flooding from Grand River, Mudge built a dam (1887). In 1888 the Railroad Trestle or High Bridge was built to bring the railroad south of the river and Grand Ledge became the second city in Michigan (after Lansing) to gain electric lights. By that get older an estimated 60,000 to 70,000 people visited the Seven Islands Resort annually.
