Located off the northeastern tip of Sulawesi in Indonesia, Bangka is a small island that’s slowly earning a reputation as a dive hotspot. For years, Bangka Island's reefs, pinnacles and walls were only explored on day trips from the more popular diving hubs of Bunaken National Marine Park, Lembeh Strait and Manado. But with the establishment of several eco-friendly resorts on Bangka Island and nearby Gangga Island, this spectacular region is far more accessible.
Bangka Island lies in the Pacific Ocean (between the Celebes Sea to the west and the Molucca Sea to the east) and forms part of an archipelago that also includes the nearby islands of Gangga and Talisei. The local population relies primarily on fishing and farming to make a living, giving the area an authentic, laid-back atmosphere. Bangka is located in the heart of the Coral Triangle, a globally recognised centre of marine biodiversity.
Since the opening of its first dive resort back in 1987, Bangka has grown in popularity amongst scuba enthusiasts and there are now more than 30 known dive sites in the surrounding waters. The area is particularly renowned for its magnificent soft corals and dramatic pinnacles, as well as its frequent sightings of dugongs, which come to feed on the seagrass beds.
In this article, we’ll explain everything you need to know about diving Bangka Island, including what you can expect to see and the best time to visit. We’ll also introduce some of the best dive sites around Bangka Island and eco-friendly places to stay, helping you plan a sustainable dive vacation in Indonesia.

Diving Bunaken National Marine Park and Lembeh Strait from Bangka Island
Bangka Island is strategically positioned between Bunaken National Marine Park (to the southwest) and Lembeh Strait (to the southeast), two of the most spectacular dive destinations in Indonesia. Bunaken is famed for its dramatic coral walls that plunge precipitously into the abyss and waters of exceptional clarity.
In contrast, Lembeh Strait has earned a reputation as the "Critter Capital of the World," luring adventurous underwater photographers in search of the rare and the unusual. The unique muck diving sites of Lembeh harbour a staggering diversity of bizarre and captivating marine life, including frogfish, mimic octopuses and intricately patterned nudibranchs.
Bangka's location between these two premier dive destinations makes it an ideal base from which you can embark on day trips to both Bunaken National Marine Park and Lembeh Strait. Most dive resorts in Bangka Island can arrange full-day trips to explore further afield, with three dives at either location.

Best time to dive around Bangka Island
The best times to dive around Bangka Island are from March through June, as well as September and October when the weather and sea conditions are at their absolute prime. During these peak dive seasons, the visibility underwater is exceptional, often stretching for 30 metres or more, and the waters are relatively calm.
In contrast, the wetter months from November through March can sometimes result in reduced visibility and slightly rougher seas, though there are still plenty of sheltered dive sites that remain accessible. The windiest time of year, from July through August, may expose some dive locations to larger swells. That being said, most dive operators are skilled at finding calmer, more protected areas to ensure safe and enjoyable dives throughout the year.

FAQs about diving around Bangka Island, North Sulawesi
When is the best season to dive in Sulawesi?
While you can dive year-round in Sulawesi, the wet season from November through April is characterised by increased rainfall and potentially stronger currents. The dry season, which spans from May to October, brings drier conditions and calmer seas, making for especially pleasant diving experiences. That being said, the tropical climate of Sulawesi means that some precipitation is always a possibility, no matter the time of year.
One factor to keep in mind is the prevalence of strong winds that can pick up around July and August. During these months, more exposed dive sites around Bangka and Gangga may see choppier surface conditions, which could impact the overall experience and accessibility of those locations. Lembeh usually experiences a longer wet season, but as the strait is sheltered, this only really affects access to the outer reef sites.
What is the water temperature in North Sulawesi?
North Sulawesi experiences a tropical climate with water temperatures ranging from 28 to 30 degrees Celsius (82 to 86 degrees Fahrenheit) throughout the year. For most divers, a 3mm wetsuit is adequate, although it’s worth bringing an extra skin if you’re visiting between October and December when cooler thermoclines can be expected.
How do you get to North Sulawesi?
There are regular domestic flight connections to Sam Ratulangi International Airport in Manado from various Indonesian airports, including Jakarta, Bali and Makassar. The only international flights to Manado are currently from Singapore (Scoot Airlines) and Guangzhou (China Southern Airlines).
Can you dive Bunaken and Lembeh from Bangka Island?
Bangka is perfectly situated between Bunaken National Marine Park and Lembeh Strait - two of the most popular dive destinations in North Sulawesi. Most dive resorts on Bangka Island offer full-day excursions that include three dives at either of these amazing locations or you can arrange a multi-destination dive trip to stay in all three.
