Our goal is to help families build stronger bonds and be involved in the community, all while having fun. We offer sports for youth and adults, from traditional sports to esports!

Traditional Youth Sports

The Y offers year-round team sports for kids of all ages and skill levels. Every child plays at least half of every game. We welcome Y members and non-members to participate, practice and play.  Most sports are offered in 8-week sessions with one game and one practice per week for children K-8. Preschool sports typically have one practice per week with a scrimmage at the end of the season. Keep your eyes open for future registration dates.


Esports is a competitive sport through a video game requiring the use of strategy, collaboration, communication, and problem-solving skills to achieve individual or team success. And it’s bigger than ‘just gaming’. Esports allows teens to be engaged in a non-traditional sports program. Esports will be available for youth ages 9 - 17. Youth will compete against other YMCA Participants in a supervised setting. Learn more about Esports or register for available leagues at the Bayer YMCA, Carondelet Park Rec Complex, or O'Fallon Park Rec Complex

Martial Arts

The Y offers a wide range of martial arts classes for youth and adults alike. Y instructors are among the best in their respective martial art, providing an encouraging, non-intimidating, and family-friendly environment for students of all ages -- while making it fun! Students learn to strengthen their bodies and the value of hard work, discipline, honor, integrity, and respect. RiverChase YMCA has 4-week Martial Arts sessions throughout 2023. Click here to learn more and register for martial arts.

Adult Pick-Up Basketball

Adult Pick-Up Basketball is for those age 18 and up looking to have a place to work hard, play hard and have fun in a weekly full-court meetup. Check out our gym schedule for available pick-up times.


Pickleball is offered in our gym for open play. Equipment is provided. Check out our gym schedule for available times!

Child Care

The values and skills learned early in life are vital building blocks for a successful adulthood, and we believe all kids deserve a strong start and a safe place to grow. Parents trust the Y’s child care programs to support and nurture their children from infancy through the teen years and help them become strong, capable and engaged young people.

Summer Camp

At Y camp, kids have the opportunity to explore, find new talents, try new activities, gain independence, and make lasting friendships and memories. And, above all, it’s so fun! We offer camp throughout the entire summer! Our camps are designed for a wide variety of conventional interests that include arts & crafts, group games, nature exploration, swimming, field trips and more. Camps are themed weekly. Most camp activities are held outdoors with indoor activities provided based on the day and theme. Day campers are divided into groups by the grade level they are entering in the fall. Registration opens on December 26 for the following summer.
