Crystal Bay

About this site

Crystal Bay off the northeast tip of Nusa Penida is the best place on Earth to encounter the rare mola mola (ocean sunfish) between July and October, when these bizarre disc-shaped giants rise from the depths to be cleaned. The site descends sharply past 40 m and cold upwellings that attract the sunfish can drop visibility and temperature rapidly, demanding careful dive planning. The upper reef at 10–18 m is an outstanding coral garden in its own right.
