Want to explore the best dive sites in Bunaken? Discover everything you need to know about diving in North Sulawesi, including the best time to visit and eco-friendly dive resorts for a sustainable scuba vacation.

Established as one of the country’s first marine protected areas back in 1991, Bunaken has well and truly asserted its reputation as one of Indonesia’s top dive destinations. 

It encompasses the main island of Bunaken, together with Siladen, Manado Tua, Mantehage and Nain, as well as the surrounding reefs and dramatic underwater cliffs.

Bunaken National Marine Park is particularly famed for its wall dives. Some plunge hundreds of metres into the depths below. Blanketed in a dazzling array of hard and soft corals in every imaginable colour, these walls are a magnet for divers.

On a dive trip to Bunaken, you can observe a staggering variety of tropical fish, sea turtles and reef sharks. The above water scenery is equally captivating, with pristine beaches where sea turtles come to nest. 

Beyond Bunaken, the park also encompasses the muck diving sites of Manado Bay. Here, unique critters like frogfish, mandarin fish and mimic octopus can be spotted in the nutrient-rich, silty environments.

Just outside the park boundaries, the stunning reefs of Bangka Island are renowned for their soft coral gardens and dugongs. Additionally, the “critter capital” of Lembeh Strait is within easy reach. 

In this article, we’ll explain everything you need to know about diving in Bunaken National Marine Park, including what you can expect to see and the best time to visit. We’ll also introduce some of the best dive sites in Bunaken and eco-friendly resorts, helping you plan a sustainable dive vacation in Sulawesi.

Best dive sites in Bunaken National Marine Park

Manado Tua Dua

Also known as Tanjung Kopi (“Coffee Point”), this thrilling dive site lies off the coast of a volcanic island just west of Bunaken. The currents here can be strong, pulling both up and down. So it’s best for advanced divers.

But with the water movement come large numbers of dogtooth tuna, giant trevally and Napoleon wrasse, as well as eagle rays and whitetip reef sharks.

Barracuda Point

Featuring a sloping coral reef that descends into a deep channel, Barracuda Point lies just off the coast of Sipadan Island. It’s named after the large numbers of barracuda that are usually spotted here, along with schools of jackfish, bluefin trevally and giant trevally.

Grey and whitetip reef sharks patrol the blue, making this one of the best dive sites in Bunaken.

Sachiko’s Point

Sachiko’s Point is a quintessential Bunaken wall dive, with a shallow reef that plunges to well below recreational dive limits. Gorgonian sea fans decorate the wall while green sea turtles can usually be seen feeding on the reef.

Schools of trevally and bluefin tuna are among the highlights when the currents are strong. 

Mandolin Reef

Located off the west coast of Bunaken, this magnificent reef dive features a stepped wall that descends hundreds of metres. While the currents can be strong, attracting schools of tuna and whitetip reef sharks, the macro life is also wonderful.

Keep your eyes peeled for tiny crabs hidden amidst the sponges and bubble corals. 

Likuan

Comprising three vertical walls covered in coral, this site offers more than one dive. There are plenty of caverns and crevasses to explore, with a variety of nudibranchs usually found inside.

In terms of bigger stuff, you can often spot whitetip reef sharks patrolling the walls and green sea turtles feeding in the shallows. 

Muka Kampung

Famed for its macro encounters, this sloping rubble reef is located on the southeastern tip of Bunaken Island. In addition to nudibranchs, crabs and shrimp, it’s a great spot for sightings of sea snakes, eagle rays and Napoleon wrasse. In our opinion, it’s definitely one of the best dive sites in Bunaken.

Diving Bangka Island and Lembeh Strait from Bunaken

Bunaken National Marine Park lies within easy reach of Bangka and Gangga islands, two up-and-coming dive destinations off the northern tip of Sulawesi. They are notable for their magnificent reefs, pinnacles and walls. In total, there are more than 30 dive sites to explore.

Some Bunaken dive centres offer full-day trips to discover the underwater wonders of Bangka and Gangga. Alternatively, you can stay at one of the islands’ eco-friendly resorts before or after your trip to Bunaken. 

Lembeh Strait lies on the other side of northern Sulawesi’s tip. In our opinion, it’s a little too far to visit as a day trip from Bunaken.

But it’s easy to plan a multi-destination dive trip in North Sulawesi if you want to spend a few days wall diving in Bunaken and a few days muck diving in Lembeh Strait.

If you prefer to base yourself in one area to explore all of north Sulawesi’s best dive spots, we’d recommend staying on Bangka or Gangga (they are more centrally located).

Best time to dive in Bunaken National Marine Park

North Sulawesi enjoys a tropical climate, with water temperatures consistently between 28 and 30 degrees Celsius (82 to 86 degrees Fahrenheit) all year round.

Most divers find that a 3mm wetsuit is sufficient. But it’s a good idea to pack an additional skin if you’re planning to visit from October to December. Cooler thermoclines may occur during that time.

FAQs about diving in Bunaken National Marine Park

What is Bunaken known for?

When is the best season to dive in Sulawesi?

Diving in Sulawesi is possible all year long. But the wet season from November to April brings heavier rainfall and potentially stronger currents.

In contrast, the dry season from May to October offers drier weather and calmer waters, making it a particularly enjoyable time for diving. However, due to Sulawesi’s tropical climate, some rain can occur at any time of the year.

It’s also important to consider that strong winds are more prevalent in August. During this month, dive sites in Bunaken and Bangka that are more exposed may experience rougher surface conditions. This can affect the diving experience and accessibility.

Lembeh tends to have a longer wet season. But since the strait is sheltered, this mainly impacts the outer reef sites.

When to go to Bunaken?

Bunaken National Marine Park is a fantastic diving destination that can be enjoyed throughout the year, thanks to its relatively protected location.

However, the prime time for diving is typically during the dry season, which runs from April to October, offering clear skies and excellent visibility.

The wet season lasts from November to April. But don’t worry – rainy spells are often followed by sunny breaks.

About the authors

We are a team of passionate divers and surfers with decades of combined experience in the water and travelling to all corners of the globe. After years of chasing waves and descending into the deep blue, we’ve created this resource to highlight sustainably run surf camps, eco-friendly dive resorts and conservation-focused ocean trips to help inspire your next adventure.

Eco Ocean Escapes was born out of a love of the ocean, an obsession with travel and a concern about the impacts of our adventures on the environments we explore. Despite the benefits that surf and dive tourism can bring to local communities, we recognised that ocean-based adventures are not always managed in a sustainable manner.  

Through our articles, we hope to inspire those seeking a responsible surf or dive trip that is all about supporting local communities, preserving our coastal environments and the incredible marine species that inhabit our oceans.
