Off the coast of Manado, at the northeastern tip of Sulawesi, lies one of the finest dive destinations on the planet. Bunaken National Marine Park is famous for its sheer vertical coral walls — cliffs of coral dropping hundreds of meters into the blue, wrapped in some of the richest reef life in the Coral Triangle. Green turtles drift past in the shallows, schools of fusiliers shimmer over the drop-offs, and the visibility regularly stretches past 30 meters.
This Bunaken diving guide covers the park's best dive sites, the marine life you're likely to see, snorkeling options, how to get there via Manado, where to stay on the island, the best season to dive, and realistic 2026 costs — for divers and non-divers alike.
Bunaken's signature dive: sheer vertical coral walls dropping into the deep blue, covered in sponges, gorgonians and hard corals.
About Bunaken National Marine Park
Bunaken National Park was established in 1991 and covers roughly 890 square kilometers of sea around five islands: Bunaken, Manado Tua, Mantehage, Nain and Siladen. The park sits at the heart of the Coral Triangle and hosts an extraordinary density of life — several hundred coral species and thousands of fish species have been recorded here.
The signature feature is the wall diving. On Bunaken's southwestern side especially, the reef edge plunges almost vertically from about 3 meters to several hundred meters deep, forming dramatic coral canyons, overhangs and caves. Diving here feels like flying along an underwater cliff face, with the deep blue on one side and an explosion of color on the other.
Top Dive Sites & What You'll See
Most dive operators on Bunaken run two morning dives plus an afternoon or night dive, rotating through the park's classic sites.
Lekuan I, II & III — The Famous Walls
The Lekuan sites on Bunaken's southwest coast are the park's poster dives: near-vertical walls carpeted in hard corals, giant barrel sponges and sea fans, with coral canyons cutting through the reef top. Expect big schools of fusiliers and trevally, Napoleon wrasse, and the occasional passing reef shark or eagle ray in the blue. Lekuan III's wall, with its dramatic crevices, is many divers' single favorite dive in Indonesia.
Mandolin, Fukui & Sachiko's Point
Mandolin offers a gentler sloping reef with superb macro life — frogfish, leaf scorpionfish and nudibranchs hide among the corals. Fukui is a cleaning-station hotspot where turtles queue up for the local cleaner fish. Sachiko's Point mixes wall and slope with strong fish action. Night dives at sites like Lekuan reveal hunting moray eels, Spanish dancers and bobtail squid.
The Big Animals: Turtles, Dugongs & Dolphins
Bunaken's green and hawksbill turtles are legendary — it is genuinely unusual to finish a dive day without multiple turtle encounters, especially at the shallow cleaning stations. The park is also one of the few places in Indonesia where dugongs are regularly sighted, usually around Mantehage's seagrass beds. Pods of dolphins frequently play in the boat wakes on the crossing from Manado, and whale sightings are recorded in season.
Green and hawksbill turtles are everywhere in Bunaken — snorkelers at the shallow reefs meet them almost every day.
Snorkeling in Bunaken
You don't need a dive certification to enjoy Bunaken. The shallow reef tops — especially Pangalisang on the island's east side — are world-class snorkeling: coral gardens in gin-clear water, clouds of damselfish and anthias, and turtles surfacing beside you. Most resorts and day-trip operators offer snorkel trips with gear included, and the house reefs of the island's resorts are excellent for independent snorkeling straight off the beach or jetty.
How to Get to Bunaken
Fly into Sam Ratulangi International Airport (MDC) in Manado, with direct flights from Jakarta, Surabaya, Bali and Makassar, plus international connections from Singapore. From Manado, public boats and resort transfers depart from the Marina harbor area — the crossing to Bunaken Island takes about 45 minutes by public boat or 20–30 minutes by speedboat. Most island resorts include the transfer in their packages if you arrive on their scheduled boat. Day trips from Manado are also widely available: dive centers in the city run daily boats to the park's sites.
Where to Stay
Staying on Bunaken Island itself is the classic choice — you wake up on the reef, dive the morning sites before the Manado day boats arrive, and watch the sun set behind Manado Tua. Options range from simple family-run homestays (around Rp 250,000–500,000 per night, often with meals) to comfortable dive resorts with house reefs, pools and full dive centers. Staying in Manado city is cheaper and suits divers who want nightlife and restaurants, with daily dive boats reaching the same sites. For a quieter upscale alternative, Siladen Island has boutique resorts on a white-sand island within the park.

Best Time to Dive Bunaken
Bunaken is a year-round dive destination, but conditions peak in the dry months of April to October, when seas are calmest and visibility is at its best — often 25–35 meters. The wet season (November–March) can bring windier days and slightly reduced visibility on the exposed western walls, though diving continues throughout. Muck diving at nearby sites like the Lembeh Strait is actually excellent in the wet months, making a combined Bunaken–Lembeh trip a smart year-round plan. Easter and year-end holidays are the busiest periods, so book accommodation early.
How Much Does Bunaken Cost?
As a rough 2026 guide:

- Snorkeling day trip: around Rp 150,000–350,000 per person including gear and park fees.
