Summer camp is a supervised program for children and/or teenagers conducted during the summer months. Children and adolescents who attend summer camp are known as campers. The traditional view of a summer camp as a woodsy place with hiking, canoeing, and campfires is evolving, with greater acceptance of newer summer camps that offer a wide variety of specialized activities. For example, there are camps for the performing arts, rock music, magic, computers, children with special needs, and weight loss. There are also religiously-affiliated summer camps, such as those run by Evangelical Christian groups. The primary purpose of many camps is educational or cultural development. A summer camp environment may allow children to take healthy risks in a safe and nurturing environment.
