In its purest form, camp is a sustained experience which provides a creative, educational opportunity in group living in the outdoors. It utilizes trained leadership and the resources of the natural surroundings to contribute to each camper's mental, physical, social, and spiritual growth. While often referred to as summer camp, this experience exists in a number of different programs that are offered by camps on a year-round basis. These include programs that serve youth, adults, and seniors in day and resident camps and conference centers. These programs may be sponsored by agencies, religious organizations, or independent operators.
