Dive-site story
Located on the sheltered western coast of Nusa Penida facing the channel toward Nusa Ceningan, Crystal Bay features a shallow coral plateau that drops off into a deep oceanic channel. The site is world-renowned as one of the most reliable places to encounter giant sunfish when cold upwellings draw them up from the abyss to visit cleaning stations on the reef slope. Inside the bay, conditions remain relatively calm with hard coral formations and macro life, while the outer corners and channel slope demand cautious navigation due to fierce, unpredictable currents.
Famous cleaning stations frequented by oceanic sunfish during the upwelling season
Expansive hard coral gardens across the inner bay shallows
Dramatic underwater drop-off into the turbulent Ceningan Channel
Frequent sightings of banded sea kraits, hawksbill turtles, and pelagic predators
