Suanggi Island

Ambon · Banda Sea · Indonesia

Suanggi Island is the kind of place that barely exists on a modern diving itinerary, accessible only to the few dozen divers each year who book passage on Banda Sea expedition liveaboards. Named after a feared spirit in Maluku folklore, Suanggi has been avoided by local fishermen for generations, and this cultural taboo has inadvertently created one of the most pristine marine environments in the Coral Triangle. I reached Suanggi on day seven of a twelve-day liveaboard expedition out of Ambon, crossing open Banda Sea swells for hours before the island's dark volcanic profile materialized on the horizon. The island is small, uninhabited, and densely forested, rising steeply from deep water. We moored temporarily and dropped in on the southern seamount where volcanic rock rises from several hundred meters depth to within 8 meters of the surface. The seamount walls are sheer volcanic rock covered in soft corals, enormous gorgonian fans, and pristine hard coral formations untouched by human activity. The current was running hard, and we descended quickly to 25 meters. Within minutes, the first hammerheads appeared: three scalloped hammerheads at our depth, followed by a larger group visible deeper in the blue. The pelagic roster extends well beyond hammerheads. Thresher sharks with impossibly long caudal fins have been spotted on multiple expeditions. Silvertip sharks patrol deeper sections, mobula rays pass in small squadrons, and oceanic manta rays appear during plankton-rich periods. Dogtooth tuna, wahoo, and giant trevally hunt aggressively in the current-accelerated water. Diving Suanggi is not comfortable. The currents are powerful, the depth profile unforgiving, and the nearest recompression chamber is a day's sailing away. But for experienced divers seeking the last frontiers of Indonesian diving, Suanggi delivers encounters and reef conditions that have vanished from all but the most remote corners of the ocean.
