Timber Ridge consists of oak woodlands and savannas, restored and natural prairies, recreated wetlands and lakes. Spring Lake is one of only two natural lakes in the DuPage County Forest Preserve District and is not accessible by trails.
The preserve contains many other interesting natural features, including ephemeral ponds that are a haven for amphibians such as the northern leopard frog; rare and endangered plants; and colorful birds like scarlet tanagers and Baltimore orioles.
Kline Creek Farm offers educational programs including harvesting, canning, planting, maple sugaring and more. These programs are seasonal in nature and are available to school, youth and community groups. In the summer, the farm offers a unique, one-week day camp called Farmhands.
Timber Ridge has 2 miles of trails for people on foot, bike, horseback or cross-country skis and is a trailhead for the Great Western Trail and Illinois Prairie Path. (Bikes and horses are not allowed withing the Kline Creek Farm farmstead, though.)
