An appointment is required to enter the Interpretive Center at Cahokia Mounds. Please call 618-346-5160 to schedule a time to visit. If you don’t have a reservation, there is a chance you will not be permitted to enter until a time is available. This is to ensure we are following the Restore Illinois protocols and to allow visiting as safely as possible for you and our staff. We will continue to keep the safety of our visitors and staff a top priority as we navigate the pandemic and ask for your cooperation. As a reminder we are open Thursday through Sunday from 9 until 5. The grounds are open daily from dawn until dusk. We look forward to seeing you at Cahokia Mounds soon.
