Need to Know
Raven Glen's main entrance has a 2.1-mile gravel trail for hiking, bicycling and cross-country skiing, a separate grass trail for horseback riding only, and a 0.4-mile woodland walk for hiking only.
Raven Glen's west entrance offers a 2.12-mile trail for running, bicycling, horseback riding and cross-country skiing. Trails east and west of Timber Lake do not connect.
Please keep dogs leashed and on trails at all times, and pick up after them.
The northern portion of the site was formerly a campground and contains Timber Lake, two smaller connected ponds, wetlands, and an oak-hickory grove. There are also several woodland areas near Timber Lake and interspersed throughout the wetland areas along the parcel's northern border.
The southern portion of the site was a dairy farm consisting mostly of rolling cropland, a farmstead and a stream. Prior to 1998, Raven Glen Farm was used for dairy operations and houses several buildings that were once considered state-of-the-art for dairy production during the 1950s and 1960s.
Flora & Fauna
With a sandy base, Timber Lake supports the population of rare Iowa darter fish. Fishing is allowed at Timber Lake, but not at White Slough. While the Forest Preserve owns 95 percent of Timber Lake, the northern portion of the lake is privately owned and not accessible for public use.
Ongoing restoration of Raven Glen's savanna, prairie, wetlands and streams enhances the water quality of Timber Lake. It also improves habitat for wildlife, including grassland bird species like the eastern meadowlark and bobolink, and wetland birds such as great blue herons, egrets and other waterfowl.
