This popular forest preserve is located less than 30 miles from downtown Chicago and provides hikers and bikers with miles of trails that explore the scenic terrain of rolling woodlands, marshes, ponds, and streams. There is also a waterfall along the hike as well as some overlook spots for the Des Plaines River. The main crushed gravel trail is mostly used for biking and hiking and there are additional connecting side trails within the preserve that also be used to explore the area. The trails are multi-use and popular with bikers, horseback riders, and runners also so watch out for others while on the trail.
