Welcome to Olympia Gymnastics Mid Rivers!

We have been serving the St. Charles, St. Peters, and O'Fallon area since 1983. Formally known as Olympiad Olde Towne in Cave Springs, we moved into our larger 20,000 square foot facility near Mid Rivers mall in September 2008.

We currently work with over 500 gymnasts and ninjas from toddler through teen. Our separate preschool areas with scaled down equipment provides a safe and fun environment for our younger gymnasts. When you schedule a party with us, you get to experience not only a fun time playing in our large bounce house and doing gymnastics, but you also get to have your cake and open gifts in our brightly decorated party room. For more information on our Ninja Program at our Ninja City St. Peters location please visit

We are proud to be a part of the growing St. Charles County community (St. Charles, St. Peters, O'Fallon, Wentzville and Lake St. Louis). We look forward to being a part of helping to build happy, healthy, and confident children for many years to come! Questions? Give us a Call at 636-970-1800 or e-mail us at
