In the heart of the Coral Triangle, where marine biodiversity is at its peak, lies a destination every diver should have on their list: Bunaken National Park.
Located on the northern tip of Sulawesi Island, this sanctuary is not just a place to dive, it’s a stunning underwater world of coral walls and spectacular marine life.
If you’re a fan of large vertical walls and turtles, brace yourself. In this guide, we’ll tell you everything you need to know to plan an unforgettable diving adventure in one of Indonesia’s first and most important marine parks. For us, it’s a must-see destination.
Why should you dive in Bunaken?
Imagine a place where more than 70% of all fish species in the Indo-West Pacific meet. That’s Bunaken.
The key to this wealth lies in its unique geography: the coastline of its five islands (Bunaken, Manado Tua, Siladen, Mantehage, and Nain) plunges directly into depths of over 1,500 meters, creating spectacular vertical coral walls.
This park, protected since 1991, is famous for its incredible health and density of life. The generally gentle currents nourish the more than 390 types of coral and attract thousands of fish, turning every dive into a spectacle.
Bunaken’s marine life: an underwater spectacle
The biodiversity here is simply overwhelming. You’ll immerse yourself in a vibrant ecosystem where you’ll encounter:
- The city of turtles: The nickname is no exaggeration. Bunaken is world-famous for its huge population of green and hawksbill turtles. They’re so common you’ll lose count. You’ll find them resting on the ledges, feeding, or swimming gracefully in the blue water.
- Large pelagics and sharks: Although not its main attraction, the park has a healthy population of whitetip and blacktip reef sharks. The currents also attract large schools of barracuda, tuna, and horse mackerel.
- Macro Paradise: If you’re passionate about photography and small-scale wildlife, the reefs are teeming with fascinating creatures. You’ll find countless species of nudibranchs, pygmy seahorses, ghost pipefish, cuttlefish, and frogfish.
- Marine Mammals: Deep waters are a migratory route for cetaceans. It’s very common to see pods of dolphins from the boat, and at certain times of the year (March, July, and August) it’s possible to spot sperm whales and pilot whales.
The best diving spots in Bunaken
With more than 50 listed sites, it’s impossible to get bored. Most dives are done as “drift dives,” gently drifting along the walls. Here are some of the sites you can’t miss:
- Lekuan I, II, and III: Known as the “City of Turtles,” these are the most iconic spots. Vertical walls that extend into the abyss, covered in giant sponges and gorgonians, await you. Sightings of dozens of turtles and reef sharks are practically guaranteed.
- Fukui Point: A unique spot, with a gentle slope instead of a wall. It’s famous for its coral gardens, a colony of garden eels, and, most importantly, for five giant clams measuring over a meter.
- Mandolin Reef: A stepped wall with overhangs and small caves, ideal for drift diving in moderate currents. The reef’s upper reaches are a paradise for macro photography.
- Sachiko’s Point: A deep wall with one of the park’s largest concentrations of reef fish. A perfect spot to see large Napoleon wrasse and turtles.
- Mike’s Point: Named after underwater photographer Mike Severns, this wall is exposed to currents that can be strong, attracting large pelagic fish such as tuna and horse mackerel.
- Poopoh / Bethlehem: If you like unusual creatures, these muck diving sites off the coast of Manado are for you. Their volcanic sand bottom is home to frogfish, mimic octopuses, and quirky cuttlefish.
When is the best time to travel to Bunaken?
You can dive in Bunaken year-round thanks to its excellent conditions. The water temperature is warm and stable, between 27°C and 30°C. Visibility is spectacular, averaging 25-30 meters, but can reach 40 meters.
The best time to visit is during the dry season, which runs from April to October. During these months, the seas are generally calmer and the weather more stable.
???? Tip: July and August are peak season. If you’re looking for a quieter, less crowded experience, we recommend traveling in months like May, June, September, or October, when conditions are still fantastic.
Planning your trip: How to get there and where to stay
Reaching this paradise is easier than it seems. The gateway is Sam Ratulangi International Airport (MDC) in Manado, which receives direct flights from Singapore and connections from Jakarta or Bali.
From Manado, you’ll need to take a boat to the island of your choice. Most dive resorts will arrange this transfer for you, which is the most convenient option.
As for accommodation, you have several options depending on the type of experience you are looking for:
- Bunaken Island: This is the diving hub, with the widest range of accommodations, from simple homestays to mid-range dive resorts. The atmosphere is social and 100% focused on diving.
- Siladen Island: If you’re looking for tranquility, luxury, and white-sand beaches, this is the island for you. It’s ideal for a more exclusive getaway, with high-end boutique resorts.
- Manado Coast: Staying on the mainland gives you more flexibility to combine diving with land excursions, such as visiting the Tangkoko Nature Reserve or climbing nearby volcanoes.
At Karang Travel, we know the best resorts in the area and can help you choose the one that best suits your travel plans and budget.
Beyond diving: other activities in the area
Although diving is king, the region offers other worthwhile adventures:
- Tangkoko Nature Reserve: About two hours from Manado, this is the best place in the world to see the spectral tarsier, the world’s smallest primate, and the curious crested black macaques.
- Hike Manado Tua Volcano: For the more active, a 4-5 hour hike to the top of this extinct volcano will give you stunning panoramic views of the entire archipelago.
Practical information for your trip to Bunaken
- Park Fee: To contribute to conservation, all visitors must pay an entrance fee of IDR 150,000 (approximately €10), valid year-round. Your dive resort will arrange this fee.
- Currency and ATMs: The currency is the Indonesian Rupiah (IDR). It is essential to carry sufficient cash, as there are no ATMs on the park islands. You will need to withdraw money in Manado.
- Travel and Diving Insurance: Insurance specifically covering diving activities and emergency medical evacuation is mandatory. Safety comes first.
Bunaken is a captivating destination, a fragile paradise that reminds us of the importance of responsible travel. If you dream of endless coral reefs, close encounters with turtles, and an authentic diving experience, this corner of Sulawesi awaits you.
