This is a dive site rather than somewhere you walk to, out past the passage on the south side where the lagoon drains out to the open sea. Big coral heads with sand between them, blue water going dark below, and enough current that you go when the boat says to go rather than when you feel like it. Two dives in a morning and I would have done a third.
