Need to Know
Parking is also available at the Lake Barrington Village Hall on Old Barrington Road south of Kelsey Road and southwest of Miller Road.
Kelsey Road divides the preserve's two separate northern sections, but a trail tunnel and an at-grade road crossing with a flashing beacon provide safe passage at both locations. Trail connections are also provided to adjacent neighborhoods.
Trails here are open only for hiking and cross-country skiing. Biking is not allowed. Please keep dogs leashed and on the trails at all times, and pick up after them.
Silver maples, cottonwoods and willows line the banks of the Fox River and its floodwater-storing floodplain. Burly old-growth oaks occupy slightly higher ground above the river, and former agriculture fields now being restored to prairie can be viewed.
Prominent geological landforms such as kettles and kames tell of Lake County's not too distant glacial shaping, while providing sweeping views of the river valley and the surrounding area. Centuries-old landscape plantings of catalpa trees, Douglas firs, and a hedgerow of osage orange remind of us those who lived here before us.
Three rare and valuable natural features of the preserve include Wagner Fen, Flint Creek and wooded bluffs. Oak woodlands surround the fen and creek, providing habitat for songbirds, woodpeckers and hawks.
Flora & Fauna
Flint Creek One of the healthier streams in Lake County and in Illinois, Flint Creek's quality rating of a Grade B is considered rare for Illinois. With help from an Illinois Environmental Protection Agency grant, stream banks along the Flint Creek corridor were restored.
