Glacial Park spans some 3,300 acres in Ringwood, Illinois and is fondly referred to by some as the "crown jewel" of the McHenry County Conservation District. It offers a wide variety of outdoor recreational activities including, picnicking, hiking, biking, horse backing, cross country skiing, canoeing, fishing and camping.

In addition to the many special programs, park personnel also guide tours through the park at various times during the year along the 6.7 miles of winding, interconnected, trails. Park personnel in Glacial Park inventory each remnant, natural area site for fauna and flora in order to keep record of native, rare or endangered species.

In all, more than 420 plant species contribute to the beauty and rich biological diversity in the Glacial Park-Lost Valley Marsh area. There are also 222 species of birds found regularly in McHenry County. Canada geese, ducks, frogs, turtles and a variety of bird types are observed regularly around the wetlands, and around feeding time, raccoons and the occasional coyote visit the area in search of food.
