About McHenry

McHenry is a city in McHenry County, northwest of Chicago, with a history that began with settlers arriving in the 1830s. Its setting near the Fox River and Chain O'Lakes area gives it a recreation-oriented edge, and Moraine Hills State Park is nearby for trails, wetlands, and outdoor access. McHenry is also known locally for Fiesta Days, an eleven-day July festival with music, a parade, carnival, food, car shows, and art fairs. It feels like a river-and-lakes city on the outer edge of Chicagoland.
