Round Lake is a lakeside suburb in north-central Lake County where quiet residential streets and century-old oak woodlands sit just a short train ride from Chicago. Daily life here revolves around the outdoors, a close-knit community feel, and easy access to big-city amenities without the big-city pace. Railroad Avenue anchors a small but lively downtown, while the neighboring community of Round Lake Beach fills in the gaps with more dining and shopping options.
Rentals in Round Lake include townhomes, garden-style apartment communities, and smaller multi-family buildings with traditional architecture. The housing stock is largely residential in character, with the kind of spacious layouts that suburban Lake County is known for.
The same rail line that once carried ice harvested from the namesake lake to refrigerate Armour and Company railcars now carries Metra commuters 90 minutes south to Chicago Union Station. College of Lake County in Grayslake is roughly seven miles away, and Naval Station Great Lakes is about 16 miles to the southeast.
Round Lake is the perfect spot to enjoy the sun, go fishing or relax on the beach.
Living in Round Lake is an affordable option with average listing prices at $275,000.
Beautiful memorial fountain can be seen near the ample parking at Round Lake's Metra station.
Nippersink Forest Preserve joins the public sidewalk, with access to surrounding communities.
Visitors enjoy trails, picnicking, birdwatching and nature observation.
The Metra station allows commuters to travel to Union Station in downtown Chicago easily.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
