Hidden Lake Forest Preserve

About Hidden Lake Forest Preserve

Hidden Lake is one of the few places in the county where visitors can hear spring peepers in the wooded ponds. It’s also home to King’s Grove, a remnant woodland of red, white and bur oaks. It features two lakes and a river, trails, fishing, boating and picnic areas, including a new picnic shelter.
