About this site
Castle Rock sits off Catalina Island, off the coast of Southern California, in waters known for kelp forest diving. This site reaches a maximum depth of around 10 metres and is considered a beginner dive. Divers here have also reported fusilier and trevally moving through the area, though these are more commonly associated with warmer Indo-Pacific waters than the California coast.
