You are no longer allowed to wear scuba gear in the lagoons. Also, no exit or entry to the outside waters from the lagoons are allowed. A security guard put a quick end to our lagoon entry, directed us to a shore entry at one of the points from the lagoons. Shore entry turned out to be very, VERY, sharp volcanic rock, barnacles, and urchin burrowed coral/rock. Got out by careful walking and floating on my back early. Deepest we encountered was about 20 ft. Some interesting coral, standard reef fish. Exit was extremely difficult as waves throw you back into those sharp edges. Took a couple minor cuts (wore a shorty). Much better spots to dive. Would take China wall with 4-6 foot waves over this with 1-2 footers if you can't use the lagoons for entry and exit.
