The story

Mantas at the surface.

Manta Bay is a shallow cove cut into the cliffs of southwest Nusa Penida. The bay's bottom sits at 8–15 metres, and on most mornings the resident reef manta population comes here to surface-feed on plankton drifting in on the current.

Encounters are spectacular and casual — mantas circling 1–3 metres below the surface, sometimes brushing past your fins, often hanging effortlessly above you. Open Water divers see the same animals as the AOWD divers at Manta Point, just at half the depth and with calmer conditions.

"Reef mantas, shallow water, no certification gate."

Conditions can be choppy on the surface — Penida's south coast catches Indian Ocean swell. Expect a bouncy boat ride. Visibility varies with plankton bloom intensity.

Topography

How the dive unfolds.
