Bunaken
Island Island and marine park famed for coral reefs
Bunaken Marine Park off North Sulawesi is known for steep coral walls, abundant fish life and clear water; divers and snorkelers launch from Manado and nearby island resorts.
Bunaken is a small island off the coast of North Sulawesi in Indonesia and forms a core part of the Bunaken National Marine Park, established in 1991. It is best known for its marine environment and diving sites rather than large-scale built attractions.
Clear water, steep coral walls and reef gardens are the main attractions, with numerous dive and snorkel sites close to shore. The area is used for scuba diving, snorkeling and short boat trips to nearby reefs and is valued for its coral diversity and reef fish.
The island has long been inhabited by local fishing communities; the marine park designation in 1991 formalized protection of the surrounding reefs and helped develop tourism infrastructure. Management of reefs and visitor activities has involved local villages and the national park authority since that designation.
Bunaken lies off the northern coast of Sulawesi near the city of Manado in North Sulawesi province, in the Celebes Sea. The island sits within the marine park that covers reefs and islets around the northern tip of Sulawesi.
- Protected status: Part of the Bunaken National Park protected area, which was established in 1991.
- Access: Regular boat connections link the island to the city of Manado, the usual gateway for visitors.
How to Get to Bunaken #
The common route is to fly to Manado (Sam Ratulangi International Airport) on Sulawesi’s north coast; dive boats and ferries leave from Manado’s port to Bunaken island (about 30-60 minutes by boat). Many resorts and operators offer transfers from the airport.
Tips for Visiting Bunaken #
- Book dive outings to Bunaken and Manado from the port of Manado - local operators are reliable and the park has strict no-take rules to protect reefs.
- Visit the Bunaken island marine park center for a short orientation about reef etiquette - divers and snorkelers are expected to avoid touching corals.
- Bring a reef-safe sunscreen; the park and many operators enforce no-sunscreen policies to protect coral health.
