The 109-acre Oldfield Oaks Forest Preserve in Darien features 2 miles of trails through mature oak woodland, natural wetland and restored prairie. It’s a beautiful spot to enjoy spring wildflowers such as trout lilies, jack-in-the-pulpits, spring beauties, trillium and May apples, but it also puts on a spectacular show of color in the fall.
Natural Scene
Oldfield Oaks is an excellent example of an intact, mature oak woodland, a natural wetland, and a restored prairie. With this diverse mix of ecosystems, the preserve is home to a variety of wildlife, from foxes to great horned owls to western chorus frogs. Wildlife conservation efforts such as amphibian monitoring and bird counts take place at the preserve.
The Forest Preserve District has removed weedy invasive brush from several areas of the preserve to allow light to reach the woodland floor. As a result, wildflowers and other native vegetation are once again thriving at Oldfield Oaks.
Driving Directions
The entrance is 0.25 mile east of Lemont Road on the south side of 87th Street/Oldfield Road.
Oldfield Oaks has a 0.6-mile South Loop Trail and a 1.1-mile limestone North Loop Trail, which weaves through mature oak woodlands and restored prairie and has several switchbacks that offer uphill and downhill hiking.
Horseback riding is not allowed at Oldfield Oaks.
