One of our most popular spots, offering miles of trails, great bass fishing and secluded picnic spots in the heart of Lake County. Old School's sled hill is one of the most popular features of this preserve and can be seen from I-94.
Gravel trails, a paved roadway trail and a fitness trail are available here.
Please keep dogs leashed and on trails at all times, and pick up after them. Learn about our off-leash Dog Parks (permit required).
The Des Plaines River Trail winds through this preserve and is open to hikers, bicyclists, horseback riders and cross-country skiers. From Old School you can make your way south to Lincolnshire without crossing any major roads.
