Quick Overview

Marengo is a small McHenry County city in northern Illinois, sitting along US-20 about 60 miles northwest of downtown Chicago in the rolling countryside where suburban development starts giving way to farmland, horse properties, and well-maintained forest preserves. With several motorhome campgrounds and parks in the area, including some free options, Marengo offers camping in a scenic rural setting that's still within practical day-trip distance of Chicago and all of its world-class attractions, restaurants, and entertainment. The town sits at the crossroads of US-20 and IL-23, with the Kishwaukee River flowing through the area and providing wooded valleys that break up the agricultural landscape with welcome patches of shade and scenery. McHenry County is one of the more attractive counties in northern Illinois with its mix of gentle hills, meandering streams, and conservation areas that support a strong outdoor recreation scene including hiking, fishing, and bird watching. The Marengo Ridge Conservation Area nearby protects high-quality natural areas including rare prairie remnants and mature woodland habitats that are worth exploring on foot. For RVers, Marengo offers a quieter and more affordable alternative to campgrounds closer to the Chicago metro while still keeping the city's museums, lakefront, sporting events, and dining within reach for a day trip via the I-90 toll road accessible to the south.
