Annual Open House

June 4

Join us to commence our 63rd summer of “teaching what matters most.” A BBQ lunch will be served from 12:30-1:30 pm. Families will have a chance to meet leadership staff, take a tour, meet the horses, and participate in a sampling of summer camp activities including archery, climbing wall, arts & crafts, swimming, pony rides, and others. Free admission.

Registration Coming Soon!

Camp Ondessonk has proudly served campers since the summer of 1959.  Ondessonk’s 983-acre site is adjacent to the Shawnee National Forest and is among the most beautiful summer camps in the United States.  The Ondessonk Experience is deliberately designed to immerse participants in a setting not often encountered by the youths of today. This traditional approach to summer camping allows participants to fully experience their surroundings in a fun, adventurous, and supportive environment.

Camp Ondessonk is owned and operated by the Catholic Diocese of Belleville, Illinois.  Christian traditions and teachings guide the work of this ministry.  People of all faiths are encouraged and welcome to enjoy the Ondessonk experience.
