North Point Marina is an Illinois state recreation area on the Lake Michigan shore in Lake County, spanning 297 acres of protected public land anchored by a large marina. Its defining feature is its scale as a boating facility, with 1,500 slips for mooring boats, making it both a recreation area and a major harbor for pleasure craft. Today it serves as a state-managed waterfront destination where boating is central to the experience, and its significance lies in the combination of protected area status and substantial marina infrastructure.
