About Camp O
Welcome to Camp Ondessonk!
Since 1959, Camp Ondessonk has provided children and children-at-heart the opportunity to experience first hand 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.
Camp Ondessonk is the Premier Adventure Destination of the Midwest. Our camper fees are extremely competitive and unlike many other summer camps, Ondessonk does not charge additional fees for horseback riding or senior camper electives.
Camp Ondessonk offers programs to many different groups throughout the year. During the fall, winter, and spring we offer outdoor education programs to school and youth groups, challenge and high ropes courses, conference and retreat facilities, and a variety of special interest weekends and Open Houses.
A great camping experience requires more than just a facility and a program. One of Camp Ondessonk’s greatest strengths is the large number of staff and volunteers that work throughout the year to facilitate and support programs. These individuals strive to be positive role models, living lives committed to the spiritual and emotional growth of participants.
Camp Ondessonk is owned and operated by the Catholic Diocese of Belleville, IL. Christian traditions and teachings guide the work of this ministry. People of all faiths are encouraged and welcome to enjoy Ondessonk.
