O'Day Park, O’Fallon’s newest gem, is nestled in the countryside just off Highway DD. The 57-acre park offers the area's first adventure playground, a truly unique play experience for kids of all ages. The park also is home to O'Day Lodge, a premiere meeting, banquet and conference center, and outdoor amphitheater. All this, plus miles of paved and natural paths (some paths are still in development). Group camping for Scout and youth groups also is available.


O'Day Lodge

For those special occasions, educational or corporate events, O'Day Lodge at the southwest tip of the park offers all the amenities including state-of-the-art technology and class or meeting space, and an outdoor amphitheater for gatherings. Depending on the arrangement of the table layout, between 250 and 320 can be seated in the hall. Information and costs for renting the facility can be found on the O'Day Lodge webpage.

Adventure Playground & Pavilions

The pace picks up with the Adventure Playground, where unique play equipment invites kids to climb the rope course, hang together on group swings and giggle on the wooden log climbers and slides.

Watch the kids engaged in water play in the O’Day Creek Experience Area. Take a lunch break at a picnic table. Let your teens meet for some social time in the Teen Overlook. Plan to rent the Family Pavilion ahead of time for a reunion. Find the Terminus at the eastern end of the park and relax in the shady shelter.
