Mariner's Cove is the best neighborhood!

​We sure think so, and hope you do, too.

Located in Third Lake, Illinois, Mariner’s Cove is a unique community of 338 homes nestled in an area with abundant recreational opportunities. Mariner’s Cove sits between Druce Lake and Third Lake, and borders the Rollins Savanna Forest Preserve. With 225 acres of water for fishing, boating and swimming, Mariner’s Cove has the feel of an intimate resort area in the heart of bustling Lake County, Illinois.

The community is friendly, supportive, caring and outgoing." - resident of 7 years
