Those in Orange County, California, are there any tide pool areas with large biodiversity and unique organisms?

Have to do a rocky intertidal profile for a project and went down to Shaw’s Cove in Laguna Beach to do my profile. The places where octopus and nudibranch are seen most often were closed off despite it being low tide, so I really wasn’t able to explore much. I mostly saw hermit crabs, green sea anemones, and mussels. My presentation has to be a minimum of 10 minutes long and the information I’ve gathered barely gets it to 5 minutes (even by explaining all the different types of sea weed, kelp, and intertidal zones). I need to have taken the videos and pictures of these organisms and not just taken anything from the internet. That being said, are there any particular areas in Laguna Beach, Newport Beach, or any of the surrounding areas where you’ll constantly see large biodiversity every time you go?
