Lovely sea mounts—the Danglebens Pinnacles—fringe the northern edge of the submerged volcanic crater. This large flat reef connects them and shelters finger corals, large bright sponges, nurse sharks, and schools of horse-eyed jacks. Watch for turtles, rare scorpionfish, and shrimp cleaning spotted moray eels. When the current's chill, this shallow, sheltered site is an easy descent, suitable for newbies. Max depth of 50 feet (15m).
