Shallow manta bay profile and year-round sightings context.
Dive Spot Guide•
Manta Bay
Boat-access manta site with sharks and reef fish.
Local operator required
The bay is normally reached by guided boat trips rather than independent shore entry.
Boat-only access, shallow mantas, and weather-sensitive conditions make this a tour stop rather than a casual shore dive.
About Manta Bay
Manta Bay is a boat-access dive and snorkel site off Nusa Penida where steep coastal cliffs funnel plankton into the bay and bring reef mantas close to the surface. It is best treated as a weather-sensitive offshore stop: plan for swell, currents, and a short shallow profile rather than a long reef cruise, with mantas, stingrays, bamboo sharks, and reef fish as the main draw.
