About Island Lake

Island Lake is a relaxed, friendly village of about 8,000 residents in Chicago’s northwest suburbs, sitting right on the border of Lake and McHenry counties. True to its name, the community centers around an 84-acre lake complete with a small island in the middle. It gives the area a laid-back lake-town vibe, where locals enjoy quiet residential streets, waterfront parks, neighborhood beaches, and easy access to boating and fishing.

For daily life and schooling, Island Lake blends seamlessly into the surrounding area. Most school-age kids attend the well-regarded Wauconda District 118 schools, while neighboring towns like McHenry and Wauconda offer plenty of shopping, dining, and grocery options. It is a great fit for homebuyers looking for scenic, water-oriented living and a peaceful pace within driving distance of Chicago.
