Silver Springs State Fish and Wildlife Area was one of five new state parks opened in northern Illinois from 1969-1971. As part of more than 20,000 acres (80.94 km2) added to the Illinois state park system during this period, Silver Springs opened to alleviate traffic at other state parks in the area. At the time, the Illinois Department of Natural Resources (IDNR), which oversees the state park system, was attempting to provide the Chicago area with the most state park facilities in Illinois. The spring is located along the hiking trail.<br />
