Sahaung Island
Overview
Sahaung Island sits in the Bangka Strait off North Sulawesi's northern tip, a tiny volcanic rock that barely breaks the surface yet hides an underwater world of extraordinary color and diversity beneath its waves. The site is a series of submerged pinnacles rising from a sandy seafloor at 30 metres, each one smothered in soft corals so dense and vibrant that first-time visitors often struggle to process the visual overload. This is North Sulawesi diving at its most photogenic. I descended along the main pinnacle's western face and was immediately engulfed in color. Dendronephthya soft corals in shades of magenta, electric purple, and fiery orange cascaded down every vertical surface, their delicate branches fully extended in the gentle current. Schools of golden anthias swarmed the coral heads in shimmering clouds, darting in and out of the soft coral canopy with mechanical precision. The sheer density of color here rivals anything I have seen in Fiji's Somosomo Strait. But Sahaung's real treasure lies in the small. The gorgonian fans anchored to the pinnacle between 18 and 25 metres are home to multiple species of pygmy seahorse, those impossibly tiny creatures that require a trained eye and a patient guide to locate. My dive guide pointed out a Denise's pygmy seahorse barely a centimetre long, perfectly camouflaged against the orange polyps of its host fan. On the volcanic sand slopes between pinnacles, ghost pipefish hung motionless near crinoids, a painted frogfish sat wedged against a sponge, and a blue-ringed octopus prowled through the rubble. The upper sections of the pinnacles between 5 and 12 metres offered a different mood entirely: hard coral gardens patrolled by sweetlips, fusiliers, and territorial damselfish. Moray eels occupied crevices in the basalt rock. Sahaung delivers the full North Sulawesi experience in a single dive, from wide-angle soft coral spectacle to the most demanding macro subjects in the Indo-Pacific. It is a site that rewards both the patient lens and the wandering eye.

Frequently asked questions
How do I reach Sahaung Island for diving?
Fly into Manado's Sam Ratulangi Airport, then transfer by car approximately two hours north to Bangka Island or Likupang on the mainland coast. Several dive resorts on Bangka Island operate daily boat trips to Sahaung, which is roughly a 15-minute ride from Bangka. Some Bunaken-based operators also run occasional day trips, though the longer boat ride makes Bangka-based accommodation more practical for repeated dives.
Is Sahaung Island suitable for underwater photography?
Sahaung is exceptional for photography. The combination of dense soft coral backdrops, steady macro subjects like pygmy seahorses and frogfish, and moderate currents that allow careful positioning make it a favorite among underwater photographers visiting North Sulawesi. Wide-angle shooters love the soft coral-covered pinnacles, while macro photographers can spend entire dives on the gorgonian fans searching for pygmy seahorses. Moderate currents typically run on a predictable tidal schedule, allowing dive guides to time entries for calmer conditions.
What is the difference between diving Sahaung and nearby Bunaken?
Bunaken is famous for dramatic wall diving with pelagic encounters, while Sahaung offers a completely different experience centered on pinnacle topography, explosive soft coral growth, and world-class macro life. Many divers combine both areas in a single North Sulawesi trip. Sahaung sees far fewer boats than Bunaken, and its volcanic sand slopes host rare critter species not commonly found on Bunaken's limestone walls. The two sites complement each other perfectly for a varied week of diving.
