Whalon Lake Dog Park

About the Park

Set within the Whalon Lake preserve near Naperville, this off-leash dog area is part of a Will County forest preserve southwest of Chicago, giving dogs room to roam in a natural setting. There is no charge to use it. The listing does not confirm fencing, surface, or set hours, and forest-preserve dog areas sometimes require a seasonal permit, so check the preserve's page before your first visit. That is especially wise for a dog with an unreliable recall, since preserve land tends to be open rather than fully enclosed. Naperville's summers are warm and humid and winters are cold, so time outings to the weather. Bring water and waste bags, and keep to the marked off-leash zone.
