History
In presettlement times, Hawk Hollow was predominantly prairie with a patch of timber in the northwest portion of the preserve, now Gilbert’s Grove. The preserve was under cultivation after settlement, with scattered homesites.
The Forest Preserve District acquired much of the preserve in the 1970s, with smaller parcels added in the 1990s and 2000s.
In spring 2017 a bridge over County Farm Road opened connecting Hawk Hollow to Mallard Lake. The bridge and a mile of new trail completed a missing link in the North Central DuPage Regional Trail, which connects Cook County to the West Branch DuPage River Trail.
The preserve is open daily from one hour after sunrise until sunset. Dogs must be on leashes under 10 feet long, and alcohol is prohibited. Read ourRules & Regulations.
