The Avalon Harbor Underwater Cleanup is an annual dive event held at Avalon Harbor on Catalina Island. The event was started in the 1970s by the local dive community in an effort to cleanup Avalon Harbor, and this event is the only time diving is permitted in the Harbor. Over the years, this event has grown to become one of the most popular dive events in Southern California.
