On our recent trip to Indonesia, we had an opportunity to visit North Sulawesi and experience some incredible diving in this region while staying at the Gangga Island Resort & Spa. We were pleasantly surprised by the diving conditions. Not only that, the biodiversity of marine life in this area is vast. We highly recommend this region to any scuba diving enthusiast!

Diving in North Sulawesi 

North Sulawesi province is situated on the Minahasa Peninsula on the island of Sulawesi, east of Borneo. It covers an area of over 13,000 and has a population of just over 2.4 million. 

Unlike other parts of Indonesia, this region is pristine, away from modernity. So, you can say that this is the perfect spot for scuba divers. And also, those looking for a true off the beaten path experience.

As we discovered during our trip, North Sulawesi is home to some of the best diving in Indonesia. Certainly, strong currents bring nutrient-rich water from the ocean depths. It creates a thriving marine environment for a variety of inhabitants ranging from small critters to massive schools of fish.

The most popular diving destinations in the area include Bangka Archipelago, Bunaken National Park and Lembeh Strait. 

Bangka Archipelago

Located at the juncture between the Indian and Pacific Oceans, Bangka Archipelago consists of the islands of Bangka and Gangga. Additionally, with smaller islands of Lihaga, Talisei, and Tindila.

This part of North Sulawesi boasts more than 30 world-class diving locations with a wonderful variety of marine life. Expect to see green sea turtles, schools of trevally and colourful reef fish along the many walls. Bangka and Gangga Island dive sites also feature a great selection of critters.

Bunaken National Marine Park

Covering over 75,000 hectares, Bunaken National Marine Park offers a chance to see nearly every species of coral fish native to Indonesia. And, thanks to its great visibility (20-30 meters), it is considered one of the best places in the world for diving

Marine life in Bunaken National Marine Park includes eagle rays, jackfish, tuna, sharks, barracudas, turtles, and napoleons among others. Furthermore, there are at least 30 dive sites found in the area of Bunaken National Marine Park. Even more, Bunaken have plenty of unique diving opportunities for every level. 

Lembeh Strait

Lembeh Strait offers a very unique diving experience, as it is a destination known primarily for muck diving. With an average of 10-20 meters of visibility, Lembeh Strait’s 25 dive sites offer an amazing array of marine life.

What this area lacks in reefs, it makes up for in the sheer diversity of critters. Nudibranchs, eels, pygmy and giant seahorses are just some. Additionally, there’s frog-fish, Pegasus sea moths, cockatoo wasp-fish, leaf scorpion-fish as well as many others.

Sustainability Practices

Roughly 60% of the staff members are locals, and Gangga Island Resort & Spa works to help improve the health, education, and skill development of the local communities. They use profits from the resort to fund scholarships and to renovate and help construct local schools. The village on the island now also has a hospitality school, which helps prepare more locals for employment at the hotel and beyond. 

Gangga Island Resort spreads awareness on the importance of protecting marine life, and they work with the Biorock program to help regrow reefs, as well as employing sea gardeners to help with beach clean-up. We loved learning about the Biorock coral reef program and the opportunity to see the fruits of their labour first hand on an afternoon dive just in front of the resort.

While most visitors come to North Sulawesi for diving, some also enjoy exploring the regions on the ground activities. 


Manado is the capital city of North Sulawesi and the second-largest city in the region.  Surrounded by highlands, volcanic mountains, and the sea, the scenery even from the city is a sight to behold. The 4th largest statue of Jesus Christ in the world stands over the city like a guardian! Additionally, there are tons of beautiful churches to explore and get pictures of. 

The Highlands

Another day trip offered at the Gangga Island Resort & Spa is to the highlands, where you can see The Waruga, Lake Linow, Woloan, the lake at Tondano, and Tomohon. The tour departs at 7:30am and returns at 6pm. 

Tangkoko National Park

Tangkoko National Park is located about 80 kilometres or 2 hours from Manado. Surprisingly, it’s hassle-free to take a trip there! This is because Gangga Island Resort offers a tour to the National Park from the resort. 

The park is home to some unique animals, like the black-crested macaque and Tarsius tarsier. The day trip from the resort lasts 9 hours.
