Manta Point Nusa Penida

Manta Point Nusa Penida — Bali, Indonesia

Manta Point on the southwestern coast of Nusa Penida — a large island 20 km southeast of Bali — is the most reliable manta ray cleaning station in Bali's waters and one of the best in all of Indonesia.

The Cleaning Station

The manta cleaning station at Nusa Penida operates on a rocky reef at 5–12 meters depth. Reef manta rays (Mobula alfredi) approach the station in the mornings, hovering over resident cleaner wrasse that pick parasites from their gills and skin. The behaviour is patient and repetitive — a manta may circle the same 10-meter radius for 20 or 30 minutes before departing, often to be replaced immediately by another.

On good days (usually when the current is running from the south, pushing warm, plankton-rich water over the reef), multiple mantas — sometimes five or more — can be at the station simultaneously. The shallow depth and calm behaviour of cleaning mantas makes this one of the most accessible large-animal encounters in diving. An Open Water diver with 20 dives has a realistic chance of a manta descending to within arm's reach.

The Cold Water

Nusa Penida is subject to the cold upwellings that make the waters around it so productive. Water temperature can drop from 28°C to 18°C or less within a few minutes on a dive — cold enough to end a session for anyone in a thin wetsuit. A 5mm wetsuit is the practical minimum; many divers wear 7mm.

The same upwellings that make the water cold also explain why the manta cleaning station here operates year-round. The productivity is consistent enough that the mantas have established a permanent relationship with this reef.
