Easy/Moderate Dive. We departed from shore requiring a level of physical fitness. We swam approx. 100 yds out to the first Buoy (channel marker) and proceeded west following the reefs edge for approx. 150 yds to the second buoy (submerged 10 ft below surface). We continued along seam to third buoy for approx. 150 yds (submerged 10ft) and made an immediate right/north turn. We then swam an additional 30 yards to the caverns below and then began our dive. A little exhausting from shore but great for athletic types. Caverns were great for those new to diving.
