Finally did this one from shore. From the entry we went 180 degrees to a red buoy about 100 yards from shore. Once we got to the buoy we descended and headed along the edge of the reef shown in the picture, aka North Reef, in a generally western direction until the air hog (me) was at 1900 lbs. On return we head back the way we came but with a slight twist to the north, surfaced at 700 LBS about 35 meters from the beach. Max depth we got to was 33'. Very active with turtles, on one pinnacle cleaning station there were 5 turtles, bringing the total amount of turtles we saw on this dive to 10. Did not make it out to the actual swim throughs at the caverns but did see some very nice coral formations, some of the best on the island and tons of fish. Humu-humu-nuku-nuku Apua'a are everywhere, even saw them just off the beach while I was putting on my fins. Best to have a dive flag here since there are lots of boats and it is required by law anyway.
