My son and I dove North Crescent Bay trying to make it out to Seal Rock. The long swim out was just too far for the conditions. We dropped down to about 40 feet a 100 yards from the rock. The bottom was reef like with some sandy patches. We saw Garibaldi, urchins, cucumbers and some kelp. The vis was about 8 feet, the water temp was 53 at below the thermo cline and the surge was really strong. Get there early parking is limited and there are a lot of steps to the beach. I would like to go again when conditions are better.
