A job as a camp counselor can be the perfect summer gig for a high school or college student that loves kids and the outdoors. Camp counselors are powerful role models for campers, showing them what it means to be a responsible, respectful, yet fun-loving young adult. But at the most basic level, camp counselors are chiefly responsible for the safety and security of their campers.
A lot of camp counselors are former campers themselves who have graduated to counselors through a formal or informal training program. But you don't have to be a lifetime camper to get a job as a counselor. Most camps will hire any responsible young person with solid recommendations and some work experience with kids (babysitting, life-guarding or tutoring, for example). Pre-camp training sessions teach you what you'll need to know to go a good job. Another great route to becoming a camp counselor is to excel at a particular skill like crafts, tennis, swimming or backpacking, and apply for a position as an activity leader.
The American Camp Association offers some great resources for finding camp jobs.
