Lake County was created by the Illinois State Legislature in 1839. Located in the northeast corner of Illinois, Lake County borders Lake Michigan and features many ponds, streams, rivers and lakes that earned the county its name. The county is made up of high-density urban and rural neighborhoods, providing a safe place for families and businesses to call home.

The county provides residents and visitors opportunities to enjoy its natural beauty through the extensive trail network and many forest preserves. The county also is home to many recreational amenities, providing dining, shopping and live entertainment for the family to enjoy.
