Bangka Island (North Sulawesi)

Bangka Island sits off the northern tip of Sulawesi, a small island whose reefs are famous for extravagant soft corals and dramatic pinnacle scenery. It makes a natural complement to the nearby muck diving of Lembeh and the walls of Bunaken.

The diving is a riot of colour. Rocky pinnacles and slopes rise from the sand between 5 and 30 metres, blanketed in soft corals, sea fans and sponges in vivid reds, purples and oranges — the reason the area draws underwater photographers. Divers find schooling fish, reef sharks, turtles and eagle rays on the pinnacles, alongside abundant macro life including pygmy seahorses, nudibranchs and frogfish on the slopes. Visibility varies with the current, typically 10–25 metres.

Conditions favour competent divers. The pinnacles can be swept by current, which fuels the soft-coral growth but makes an Advanced Open Water certification and good buoyancy valuable; sheltered reefs suit Open Water divers. The warm 28–30°C water keeps exposure protection minimal, and dives are guided from resort boats.

Bangka is a small-resort destination. A handful of dive resorts sit on and around the island, reached by road and boat from Manado in North Sulawesi. Its position allows itineraries that combine Bangka's soft-coral pinnacles with Lembeh's critters and Bunaken's walls in a single trip. Diving is possible for much of the year, with the calmest seas and best conditions generally from March to November. Bangka suits divers and photographers drawn to colourful reef scenery. A contested plan to mine the island for iron ore was overturned to protect its reefs, a rare win for dive-led conservation in Indonesia.
