Camp counselors supervise and educate children and teens in day and overnight camping programs. They plan and lead activities based on the nature of the camp and their specialties. For example, a summer camp may include swimming lessons, and the camp counselor must be able to teach, supervise, and perform CPR during swim sessions. A drama camp may need a camp counselor to instruct young kids on acting techniques for a stage performance. Camp counselor duties may also include overnight supervision, food service, outdoor training, and basic first aid.
