The closest airport is Midway Airport in Chicago but O'Hare has more flight options.
Driving from Chicago takes about 45 mins depending on traffic and where you're coming from in the city, there is a parking lot at the park and street parking surrounding.
The central Metra train station is downtown Chicago at Union Station at the corner of Canal and Jackson streets. If you take the Metra train, you'll take the BNSF train toward Aurora and get off at the Brookfield stop. You can use the link below to see the schedule or purchase tickets:
