Outdoor Education

processingCamp Ondessonk’s mission and vision of getting youth outside doesn’t end when our last summer campers head for home. In keeping with that mission all year-round, Camp Ondessonk serves over 1,500 students a year in our unique and rustic setting.  Since 1988, we have been providing interdisciplinary Outdoor and Environmental Education programs for Catholic and non-Catholic schools from Illinois, Missouri, Indiana, and Kentucky.

Camp Ondessonk is 983 acres of wooded hills, sandstone canyons, and waterfalls adjacent to the Shawnee National Forest. Our unique location provides an ideal setting for experiential learning – that is, learning by doing.

It is advised that schools contact Camp first to inquire about availability and make reservations several months in advance – especially larger groups and for dates during the busier months of April, May, September, and October.  Call (618) 695-2489 or email greg.santen@ondessonk.com.

What We Do

Pakentuck Waterfall Camp Ondessonk ExperienceCamp Ondessonk works closely with educators and group leaders to create a dynamic experiential curriculum providing students with hands-on learning. An Ondessonk Outdoor Education experience promotes group building, communication skills, and leadership development as well as creates a sense of stewardship towards the natural world. Our programs focus on the principles of interdependence, in particular one’s relationship to the natural world as well as a relationship with the people around them. A school program at Ondessonk also promotes a student’s personal growth in the areas of self-esteem, trust and teamwork.

  • Multidisciplinary in nature. Our programming options provide curriculum enrichment to many subject areas on the elementary and secondary levels.
  • Active exploration, drawing on the senses of touch, taste, smell, sight, and hearing.
  • A strong focus on group interaction, cooperative learning, and critical thinking/problem solving skills.
  • The development of skills, attitudes, and concepts focusing on the interdependence between human beings and the natural environment.
