Halmahera is one of Indonesia’s most rewarding yet least-travelled diving destinations. Positioned between North Maluku and North Sulawesi, it lies right in the heart of the Coral Triangle, an area known for having the richest marine biodiversity on the planet.
Because it is remote and less developed for tourism, Halmahera has remained a hidden gem, offering pristine reefs, vibrant marine life, and a genuine sense of exploration. Mikumba Diving now offers new trips to this remarkable region aboard Jelajahi Laut, giving divers the chance to discover sites that few people have experienced.
Whether you enjoy pelagic encounters, macro life, or dramatic underwater scenery, Halmahera provides an unforgettable mix of everything that makes Indonesia such a world-class diving destination. Below, we highlight the six best dive spots in Halmahera to help you plan your next adventure.
1. Ternate
Ternate is a striking volcanic island with steep walls and consistently exciting conditions. The diving here ranges from fast-paced current dives to slower drifts along colourful coral slopes.
The deep walls attract pelagic species such as sharks, barracuda, and tuna, while the reefs are also home to a surprising amount of macro life, including nudibranchs and pygmy seahorses. Because currents can be strong, Ternate is ideal for divers who enjoy a bit of challenge and want to experience different dive styles in one area.
The combination of large marine life and small critters makes it a highly varied and rewarding place to start a Halmahera itinerary.
2. Pulau Tifore

Pulau Tifore is one of the most iconic stops in Halmahera, known for its enormous schools of fish. Divers regularly encounter swirling “tornadoes” of barracuda, jackfish, and snappers, forming dramatic patterns in the blue.
These huge schools often circle divers from multiple directions, creating a memorable and sometimes overwhelming experience. The visibility is usually excellent, and many dives here involve drifting or hovering quietly at the edge of the reef while waiting for the schools to pass.
You may also see predators such as trevallies hunting through the action.
Who it’s ideal for:
Divers who love wide-angle photography, large schools of fish, and high-energy pelagic moments. Pulau Tifore is particularly enjoyable for those who like drift dives and open-water scenery.
3. Goraici Islands
The Goraici Islands offer a wonderful mix of coral-covered walls, shallow reefs, and sheltered bays, making them suitable for both day and night diving. These islands are rich in marine life, with sightings of blacktip reef sharks along the walls and a huge variety of small creatures tucked among the corals.
Night dives are especially rewarding, with octopus, crustaceans, nudibranchs, and the occasional hunting fish appearing out of the darkness. Because the conditions here are so consistent, Goraici often becomes a favourite stop on the Halmahera route.

4. Patinti Strait

Patinti Strait is known for offering both pelagic excitement and excellent macro opportunities. The Strait acts as a natural channel for nutrient-rich water, attracting species such as:
- Tuna
- Mackerel
- Trevallies
Divers can enjoy thrilling drifts where schools of fish sweep through the blue. In contrast, the protected areas of the strait provide some of the best macro diving in the region.
Here you can find nudibranchs, juvenile fish, seahorses, and shrimps hiding among the coral heads and sandy patches. This blend of big and small life makes the Patinti Strait a favourite for divers who want variety in their underwater experiences.
5. Bacan Island
Bacan Island is famous for its black sand slopes, which create excellent conditions for muck diving. Similar to areas like Lembeh Strait, this site is perfect for divers who enjoy searching for unusual critters.
You can expect to see frogfish, ghost pipefish, cuttlefish, nudibranchs, and other well-camouflaged species. Because the dark sand provides a contrasting background, underwater photographers often consider Bacan Island one of the best places in Halmahera for macro photography.
Here, patience is key: the slower you move, the more you will find.
6. Bau & Morotai Islands
The northernmost sites on the route, the Bau and Morotai Islands, offer more dramatic underwater topography, including:
- Steep walls
- Canyons
- Fast-paced drift dives
These deeper, more open-water sites attract larger pelagic species, with divers occasionally seeing mantas, reef sharks, and big schools of fish. The reefs are healthy and colourful, and the volcanic formations create beautiful backdrops for both wide-angle and natural-light photography.
For divers who love adventurous conditions and the feeling of being in remote, untouched waters, Bau and Morotai are perfect.
