Kusu Island Resort is a remote dive resort located in South Halmahera, Indonesia, within the heart of the Coral Triangle. Set on a small tropical island surrounded by fringing reefs, mangrove forests, and lush rainforest, the resort offers direct access to one of Indonesia’s least explored diving regions. With very limited tourism infrastructure in the surrounding area, divers can experience healthy reef systems and minimal underwater traffic compared to more established Indonesian dive destinations.
The waters surrounding Kusu Island support an impressive variety of marine habitats, ranging from coral-covered reef slopes and walls to channels, seagrass beds, and offshore pinnacles. This diversity creates opportunities for both macro enthusiasts and wide-angle photographers, with encounters ranging from tiny reef critters to larger pelagic species. The resort’s location also places guests within easy reach of numerous dive sites spread throughout South Halmahera’s protected marine environment.
Facilities & Meals
The resort features an overwater restaurant and lounge, a dedicated dive centre, equipment storage facilities, rinse tanks, and boat jetties providing easy access to nearby dive sites. Meals are served three times daily and combine Indonesian flavours with international cuisine. Fresh seafood, locally sourced produce, tropical fruits, snacks, tea, and coffee are available throughout the day, ensuring guests remain well-fuelled between dives and excursions.
Activities
While diving remains the primary attraction, guests can also enjoy snorkelling, freediving, kayaking, birdwatching, and guided island excursions. The surrounding mangrove forests and rainforest areas provide opportunities to explore local ecosystems, while visits to nearby villages offer insight into traditional island life and culture.
The island sits within a protected marine environment where fishing pressure is limited and conservation efforts help preserve reef ecosystems. The underwater landscape includes coral gardens, reef walls, mangrove systems, seagrass meadows, pinnacles, and current-swept channels. These varied habitats support a remarkable range of marine life and create highly diverse diving opportunities throughout the region.
Staying Connected
Wi-Fi is available in selected areas of the resort, although connectivity can be limited due to the remote location. Internet access may vary depending on weather conditions and network availability, making Kusu Island an ideal destination for travellers looking to disconnect from daily routines.
We Think…
Kusu Island Resort is an excellent choice for divers seeking a remote Coral Triangle experience away from crowded dive destinations. Its combination of healthy reefs, diverse marine life, comfortable overwater accommodation, and access to rarely visited dive sites will appeal to photographers, marine life enthusiasts, and adventurous divers looking to explore a lesser-known region of Indonesia.
Getting here
Most international travellers arrive via Jakarta or Bali before connecting to regional airports serving North Maluku. From there, resort transfers are arranged to South Halmahera, followed by a boat journey to Kusu Island. Travel typically requires several flight connections and coordinated transfers, reflecting the resort’s remote location. Guests receive detailed travel guidance from the resort prior to arrival.
Kusu Island Resort offers eight spacious Ocean Villas positioned on stilts above the water. Each villa combines traditional Indonesian design with modern comforts and provides direct access to the surrounding sea.
Ocean Villas
The Ocean Villas measure approximately 72 square metres and feature air-conditioning, ensuite bathrooms, room safes, minibars, comfortable bedding, and large private decks overlooking the ocean. Constructed using natural materials that blend with the surrounding environment, the villas provide a peaceful atmosphere and a high degree of privacy. The open-plan design maximises natural light and sea views, while Balinese-style bathrooms include open-air elements and freshwater showers. Positioned along the shoreline between mangroves and tropical forest, the villas offer sunrise views and immediate access to the water directly from their decks.
Kusu Island is located in South Halmahera, North Maluku, Indonesia, within the globally significant Coral Triangle. This region is recognised as the centre of marine biodiversity, supporting one of the highest concentrations of coral and fish species found anywhere on Earth. The surrounding waters remain relatively untouched by large-scale tourism, helping maintain excellent reef health and ecological diversity.
Diving Location Features
Diving around Kusu Island encompasses a diverse range of underwater environments including coral gardens, reef slopes, walls, caves, pinnacles, mangrove habitats, and current-swept channels. Situated within a protected marine area, the reefs benefit from healthy coral growth and support exceptional biodiversity characteristic of the Coral Triangle.
Marine life ranges from tiny macro subjects such as nudibranchs, pygmy seahorses, shrimp, and crustaceans to larger species including reef sharks, tuna, eagle rays, manta rays, and occasional dolphins. The varied topography and oceanographic conditions create opportunities for both relaxed reef diving and more adventurous drift dives.
Best Time to Dive
Kusu Island Resort offers diving throughout the year, with generally warm water temperatures ranging between 27°C and 30°C. Visibility typically varies between 15 and 30 metres depending on tides, currents, and seasonal weather patterns.
The most favourable diving conditions are usually experienced between October and May when seas tend to be calmer and visibility is often at its best. During this period divers can enjoy excellent reef conditions, abundant fish life, and reliable access to the region’s more exposed dive sites. The months between November and April also provide increased opportunities for encounters with larger pelagic species including reef sharks, tuna, rays, and seasonal visitors moving through the channels.
The remaining months continue to offer productive diving, particularly for macro enthusiasts, as sheltered sites and house reefs remain active year-round with a wide variety of smaller marine life.
Dive Services
The dive centre is located adjacent to the resort’s jetty, providing direct access to both the house reef and dive boats. Most dive sites are located within a short boat journey of the resort, allowing flexible dive schedules and maximising time spent underwater.
Guided diving is standard, with experienced local dive guides selecting sites based on weather conditions, currents, and guest experience levels. Air and Nitrox fills are available, along with equipment rental and support for snorkelling and freediving activities. Dive courses can also be arranged in advance for guests wishing to expand their certifications during their stay.
House Reef (Pulau Kusu)
The house reef offers convenient shore access directly from the resort and provides excellent diving throughout the day and night. Coral bommies, reef slopes, and sandy patches support a surprising variety of marine life, making it an ideal site for photographers and macro enthusiasts. Divers regularly encounter nudibranchs, pipefish, shrimp, octopus, juvenile reef fish, and a variety of crustaceans hidden among the coral formations. Night dives often reveal hunting cuttlefish, crabs, and other nocturnal species emerging from the reef.
Channel Dive Sites
The channels between the islands create some of the region’s most dynamic diving conditions. Nutrient-rich currents attract schools of fusiliers, jacks, surgeonfish, and barracuda, while larger predators patrol the blue water beyond the reef edges. Depending on conditions, divers may encounter reef sharks, eagle rays, tuna, and manta rays moving through these underwater corridors. The combination of strong currents and abundant marine life makes these sites particularly appealing to experienced divers.
Reef Slopes and Coral Gardens
The reef slopes surrounding Kusu Island are covered with healthy hard and soft corals that extend into deeper water. Large table corals, branching corals, sea fans, and sponge formations create habitat for countless reef inhabitants. Schools of anthias and chromis hover above the coral while butterflyfish, angelfish, triggerfish, and wrasse move throughout the reef structure. Turtles are frequently encountered grazing among the coral gardens, while occasional reef sharks cruise the deeper sections of the slopes.
Caves, Overhangs and Pinnacles
Several dive sites feature dramatic underwater topography including caves, swim-throughs, overhangs, and submerged pinnacles rising from deeper water. These structures provide shelter for large schools of snapper, sweetlips, and glassfish, while predators often gather around the exposed sections of the reef. Moray eels, lionfish, groupers, and trevallies are common residents, and the surrounding currents occasionally attract larger pelagic visitors. The varied terrain also creates excellent opportunities for wide-angle photography.
Macro Dive Sites
South Halmahera has become increasingly recognised for its exceptional macro diving. Dedicated macro sites feature sandy slopes, rubble habitats, and protected reef areas where small marine creatures thrive. Divers may encounter pygmy seahorses, ornate ghost pipefish, frogfish, nudibranchs, mantis shrimp, boxer crabs, and a variety of rare crustaceans. These sites reward patient observation and are particularly popular with underwater photographers seeking unusual and difficult-to-find subjects.
