Welcome to Olympia Ninja 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. Ask us about our growing and exciting NINJA program!

We currently have over 75 ninjas ages 4 – teens. We have specialized ninja equipment that makes for a fun and challenging environment for our ninja classes.

We also host Ninja Birthday Parties. 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.

We offer the following classes and special activities

  • Ninja Kids (ages 4-6)
  • Ninja classes (Ages 1st grade & up)
  • Competitive Ninja Team
  • Ninja Open Gym: Wednesdays 8:00p-9:00p & 2nd Saturday 12:00p-1:00p

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?
