Central Sulawesi, Indonesia

The fish that defined an archipelago.

Banggai is a Sulawesi archipelago of 800+ small islands. It gave the world the Banggai cardinalfish — a black-and-white striped reef fish found nowhere else on Earth. We design conservation-aligned diving trips here.

Why divers come to Banggai.

Banggai cardinalfish

Endemic species, mouth-brooding parents (males protect eggs in their mouths). Listed CITES Appendix II in 2007. We dive sites with breeding populations.

Untouched reefs

Almost no commercial diving infrastructure. Visit dive sites where you’ll be the only divers most days. Healthy soft coral gardens, intact reef systems.

Sea nomads (Bajau)

The Bajau have lived as semi-nomadic seafaring people in Banggai waters for centuries. Visit communities living on stilt villages over the reef, by invitation.

Banggai Cardinal Initiative

A small operation built around conservation, not tourism volume.

We run two trips per month, 6 guests max. Our dive guides are trained in conservation protocols. We work with local communities on reef monitoring and the cardinalfish census.
