Activities at an overnight summer camp are an important part of the camper experience. Trying new activities is an important part of every day.

At Catalina Island Camps, we have a wide variety of activities. Read on for more information. Grades listed are for the grade campers just completed before camp, and not the grade they are entering next year.
