      Marengo Ridge Conservation Area is one of McHenry County’s most popular and treasured areas. It contains over 818 acres of oak and hickory woodlands interspersed with spruce, aspen, ash and sumac groves.

      Hikers can explore 5 miles of trails as they wander through majestic oak woodlands and savanna. The 1.3 mile Kelly Hertel Nature Trail meanders through woodlands and crosses several small bridges that cover ephemeral streams that lace the moraine and drain into the nearby Kishwaukee River. The trail becomes steeper, the woods thicken and the path becomes more twisted. Another route is the 1.1 mile Long Hiking Loop flows into the Kelly Hertel Nature Trail for a combined 2.6 mile hike. The 1.25 mile South Hiking Loop trail travels through restored woodlands and prairie.

      In the winter when conditions are right glide through the blanketed woodlands on Cross Country Skis.

      For those who enjoy sleeping under the starry skies, Marengo Ridge offers an exclusive use campground for 1 to 100 people. For a frosty winter excursion Marengo Ridge is also open for winter camping from December–March. In addition, Thomas Woods Campground, located on the east side of the site, has another 29 individual tent sites and 18 RV sites that can be reserved.
