Ok so I did it seeing as no one has ever done this, well the 100 people that looked at my post anyway.
Booked the trip through Eco Dive Centre, very smooth transaction with loads of follow up phone calls and info provided closer to the day. Went aboard Giant Stride from Marina Del Rey, approximately 25 mins to get to the dive site. Suited up and did a giant stride off Giant Stride with my buddy. This was at dusk but we both had our lights on. Descended to 25 - 30ft and found out there was about 2ft of viz. Carried on with the dive despite bad viz and discovered a very untouched eco system. Horn sharks, Lobster, Scorpion Fish and Garibaldi were abundant and were frequently spotted during the 35 minute dive. I can only imagine what this place would be like during a flat spell with good visibility. A great dive none the less and highly recommended.
