A junior camp counselor assists senior counselors and other camp staff members as they plan and oversee activities for campers. As a junior counselor, you typically work under a leader who is in charge of a group of campers and plans recreation activities for them. Junior camp counselors are usually teenagers. Your duties and responsibilities can vary depending on the needs of the senior camp counselor. You may be responsible for planning specific activities or monitoring a smaller group of campers within the larger group. This is usually a temporary position during the summer.
