Malaga Cove is one of two spots on the Palos Verdes Peninsula that has easy beach access. The other being White Point. I've dived Malaga cove quite a few times and it's either hit or miss. When it's good, I've found 25ft+ visibility. When its bad, it could be less than a foot. The good thing about Malaga is that it's extremely shallow. You have to go really far out to get over 40 ft and most points of interest are at 25 to 30. You'll encounter plenty of garibaldi, opaleye, sargo, senorita, and a few sheep head. As well as some lobster, if you know where to look. Most divers enter over the rocks by the yacht/dive club and then plan their dive perpendicular to the club. If a high southern swell is up Malaga can be a safe haven for divers. If a Northern swell is brewing, you're better off diving elsewhere.
