Camp O Day commemorates the founding of Camp Ondessonk.  First celebrated in 2021 and held annually on June 28, the date that the first campers came through the Camp gate in 1959, Camp O Day celebrates the tradition of giving back to Camp Ondessonk.  This one-day effort encourages gifts of time, talent, and treasure to ensure Camp Ondessonk will “teach what matters most” for years to come.

Since that first summer, Camp Ondessonk has provided the opportunity to experience firsthand the beauty of God’s creation. Located in the Shawnee National Forest of Southern Illinois, Ondessonk’s summer camp programs provide an experience that encourages campers to have fun, grow spiritually, make friends, grow in self-confidence and self-esteem, and develop values. All of Camp’s programs focus on providing a fun and enriching experience for participants by encouraging them to participate in a wide variety of new and exciting activities.
