The preserve contains an extensive 160-acre savanna and woodland restoration project.
It is home to the West Branch DuPage River, which underwent significant natural channel design restoration to improve water quality and aquatic habitat.
The site was historically part of the farmland and floodplain area before being acquired for conservation.
The park provides critical nesting habitat for several species of grassland birds that are declining in the region.
The preserve's trail system serves as a key link in the Illinois Prairie Path network.
McDowell Grove Forest Preserve spans 465 acres along the West Branch of the DuPage River in Naperville. The site features a 2.5-mile segment of the West Branch Regional Trail, which connects to the larger DuPage County regional trail system. Visitors have access to a boat launch for non-motorized watercraft, such as canoes and kayaks, on the river. The preserve includes a picnic shelter with electricity and multiple open turf areas for recreation. The landscape consists of a mix of restored tallgrass prairie, wetlands, and deciduous woodlands. Fishing is permitted along the riverbanks, subject to Illinois Department of Natural Resources regulations. A historic stone shelter, constructed during the 1930s, serves as a notable architectural feature within the park. The preserve acts as a significant corridor for migratory birds and local wildlife.
