Good spot for the casual diver (Open water) sightseeing but there are much better spots in the area that are a bit harder to get to. I dove it a few times back in the 70’s & 80’s but I haven’t been back since.

Plenty of kelp. Diversity abundant. Even saw some sea lions at the dive site, but were out of water at the current time and didn’t get to dive with them!

For California, it’s great. The water can be cold at times (especially Jan-May). Vis is 10-40 feet depending on conditions. There are some fish, not a lot when compared to other places, but for So Cal, it’s good. Shore access is easy and there is a refill station right on the shore line. Weekend crowds can be heavy at times. But all in all, a good spot for a weekend. I would recommended to people in So Cal, but not so much for those looking for a dive destination. If your in LA, is a great place for a day trip. But if you are near LAX, you can fly to Loreto Mexico (where you would see more fish) for about the same price (including hotel and food) and in about the same time as it would take you to get to Casino Point.
