About this spot

Fort Kalamata sits on Ternate Island in Indonesia's Maluku Islands, a region steeped in maritime history and natural richness. The dive site centers on the submerged remains of this historical fort, offering a unique blend of cultural exploration and marine observation. The site attracts divers interested in wreck and historical diving combined with tropical reef environments. The Maluku Islands sit within one of the world's most biodiverse marine zones.

Local community videos document the site's conditions and wildlife, providing divers with real-world footage before planning visits. Diving here is possible throughout the year, making it accessible for flexible travel schedules. The site remains outside marine protected areas, though coral health warrants attention—the region is under coral bleaching watch.

Access to Ternate is straightforward via Ternate International Airport, with dive operators available locally. The combination of historical context, marine biodiversity, and year-round accessibility makes Fort Kalamata a compelling choice for divers seeking something beyond standard reef dives.

Even just looking at the marine charts made me incredibly excited. Today, Halmahera is finally starting to gain recognition as one of Indonesia’s top diving destinations. If any of you would like to explore North Maluku,
