What Makes the Banda Sea a World-Class Diving Destination
For divers seeking adventure off the beaten paths, the Banda Sea is a true hidden gem. Far from the crowds that tend to flock to Indonesia’s more popular dive spots, this remote region offers you the chance to enjoy a peaceful diving adventure among vibrant corals and all sorts of fascinating marine life.
A Volcanic Underwater Landscape
There are three things that make the Banda Sea truly fascinating. As it is located in the Pacific Ring of Fire, its underwater landscape is dotted with volcanic topography, such as underwater ridges or pinnacles that rise from the depths, creating a surreal atmosphere.
Rich Marine Life and Pristine Reefs
The volcanic activity in the region also enriches the waters of the Banda Sea with nutrients, creating ideal conditions for vibrant marine life to thrive. From colorful reef fishes and sea snakes, to pelagic species like hammerhead sharks and manta rays, you can witness all these fascinating creatures here.
What’s more, the Banda Sea’s remote location and lower tourist activity mean that the coral reefs in this sea can thrive and flourish. Many of the dive sites here remain untouched, offering crystal-clear visibility and healthy coral formations. Whether you’re after rare pelagic or untouched reefs, the Banda Sea will offer you a wild and unforgettable diving experience.
Geographical Overview: Where is the Banda Sea?
The Banda Sea is located in the eastern part of Indonesia, nestled among the Maluku Islands. It lies near several notable islands, including Ambon to the northwest, Timor to the south, and Sulawesi to the west.
It’s also bordered by other seas, the Ceram Sea to the north and the Halmahera Sea to the east. These surrounding seas influence the Banda Sea’s ocean currents and help shape its unique marine habitats. The result is a complex network of coral reefs, ridges, and underwater formations that support a remarkably diverse range of marine life.
Historically, the Banda Sea once held great importance as part of the “Spice Islands,” which are known for their valuable nutmeg and cloves during the Age of Exploration. Its strategic location made it a critical hub for global trade, drawing explorers, traders, and colonial powers seeking the coveted spices.
Top Dive Sites in the Banda Sea
So, when it comes to Banda Sea diving, which dive sites should you explore? Here’s a list of the top spots for scuba diving in the Banda Sea!
1. Manuk Island (‘Snake Island’)
The first diving spot to explore is Manuk Island, an island that is famous for its large populations of sea snakes, which earned it the nickname ‘Snake Island’. Scuba divers flock to Manuk Island for the rare opportunity to encounter olive and banded sea kraits in their natural habitat, often coiling around coral reefs and hunting for fish. Aside from the sea snakes, the site also features thriving coral gardens, schools of barracuda, jacks, and occasional appearances from hammerhead sharks.
2. Nusa Laut
A dive in Nusa Laut is something you don’t want to miss. As you submerge yourself into the water, you’ll be greeted with pristine, healthy hard coral gardens and excellent visibility, thanks to the locals’ consistent efforts in protecting the ocean environment. This site, located southeast of Ambon Island and a part of the Lease Islands in Maluku, can only be reached by a liveaboard, but the visit will be very much worth it. Aside from the corals, you can see all sorts of marine creatures, from reef sharks to sea turtles and blue-ring octopuses.
3. Banda Neira
Offering a steep history and exceptional marine diversity, Banda Neira is another dive location within the islands of Banda that you should include on your list. Its underwater landscapes are some of the most pristine and diverse in Indonesia, with nutrient-rich waters that make it ideal for corals and marine creatures. The region is also famous as a hammerhead shark sighting spot, but you can also find creatures like tunas and manta rays, as well as critters like pygmy seahorses and ghost pipefish.
4. Hatta Reef & Hatta Island
Located on the outer edge of the Banda Islands, Hatta Reef and Hatta Island offer a pristine underwater ecosystem with unique landscapes, including coral-covered plateaus and steep drop-offs. The currents are strong, which brings in nutrient-rich waters that attract various species. You can expect encounters with schools of barracuda, giant trevally, white-tip and black-tip reef sharks, as well as green sea turtles, clownfish, and various nudibranchs. What’s more, you can also spot manta rays and migrating whales during certain seasons, and the sight of these majestic creatures gliding through the water is a rare and unforgettable experience that leaves divers in awe.
5. Serua Island
Serua Island is a dive site located near the edge of a volcanic ridge, offering unique underwater landscapes for every diver. Its healthy coral gardens and nutrient-rich waters mean this site is a hotspot for a great variety of sea animals, including pufferfish, as well as schools of tuna and jacks. What’s more, Serua Island is also a standout place to dive with hammerhead sharks. These creatures are often seen cruising through the deep waters, particularly during the hammerhead season.
6. Suanggi Island
With underwater cliffs and vibrant coral walls, you wouldn’t want to miss the chance to dive in Suanggi Island. The strong currents around this island attract many large sea creatures, including hammerhead and reef sharks, as well as occasional sightings of silky sharks and manta rays. Trevallies, anthias, and fusiliers are also commonly seen in large schools around Suanggi, often swirling around divers.
7. Run Island
The Run Island was one of the famous “Spice Islands” in the Banda Sea’s Spice Trade history. However, below its waters, an underwater paradise unfolds. This island offers you the ultimate diving experience, with schools of fish floating around you and opportunities to encounter large pelagic species, like tuna, barracuda, reef sharks, or hawksbill and green turtles. Its thriving soft coral gardens are home to various macro critters, so you might want to bring your diving camera with you to capture these fascinating critters.
Best Time to Dive in the Banda Sea
The best time to dive in the Banda Sea generally ranges from March to April in the dry season and September to December in the wet season. During these periods, the seas are calmer, with excellent visibility and a higher chance of spotting pelagic species. In particular, the months of September to October mark the hammerhead shark season, making it the ideal time to encounter schools of scalloped hammerhead sharks—especially around dive sites like Banda Neira, Suanggi Island, Serua Island, and Hatta Island.

Banda Sea Travel Tips
Due to its remote location, there are several things you need to prepare before going on a trip to the Banda Sea. To help you get started, here are several Banda Sea travel tips you can follow:
1. How to Get to and Around the Banda Sea
To get to the Banda Sea, you’ll need to fly to Jakarta or Bali, Indonesia. From there, you can board a direct flight to Ambon, which is the ideal gateway to reach the Banda Sea.
Once in Ambon, the easiest way to get to the Banda Sea and explore its dive sites and islands is by a liveaboard. Liveaboards not only offer multiple daily dives and full-board amenities, but also efficiently cover the distances between remote dive sites in the Banda Sea.
Because Ambon is a well-known departure point for these expeditions, booking your liveaboard well in advance is essential, especially during peak diving seasons, to secure your spot and ensure a smooth, immersive dive experience.
2. What to Pack
Since getting to the Banda Sea will almost always require a liveaboard, you’ll want to pack for a liveaboard trip carefully to ensure you’re fully prepared for an extended stay at sea. This means bringing all of your essential diving gear and any personal equipment you prefer.
Additionally, remember to pack reef-safe sunscreen to protect your skin from sun exposure without harming the reef. Lightweight, breathable clothing is a must for the warm weather on board. And if you’re into underwater photography, don’t forget to bring your camera gear to capture the stunning marine life.
3. Health and Safety
Going on liveaboard trips to remote regions like the Banda Sea requires some health preparation. Make sure that you have proper diving insurance that covers emergency evacuation and medical expenses. You should also make sure you already have the necessary vaccines and carry a basic health kit with items like motion sickness medication, first aid, and personal medication.
How to Practice Sustainable Diving in the Banda Sea
Preserving the Banda Sea’s underwater world is important to protect its rich biodiversity and ecosystems. Here are some practical tips and best practices for sustainable diving in the region:
1. Respect Marine Life and Coral Reefs
Be mindful of your movement in water to avoid damaging the ecosystem or startling the marine life. This includes maintaining good buoyancy control and maintaining a safe distance to allow the sea creatures to behave naturally. Resist the urge to touch or collect marine specimens.
2. Use Reef-Safe Products
Sunscreens are a must when visiting a tropical country with lots of sun exposure. However, rather than using any type of sun protection, try using reef-safe sunscreens, which are free of harmful chemicals like oxybenzone and octinoxate to prevent water pollution and coral damage (source). Additionally, you can also opt for sustainable dive gear and accessories that minimize plastic waste.
3. Minimize Waste
Minimize waste by reducing single-use plastic. Bring reusable water bottles, bags, and other essentials to reduce plastic waste on board and ashore. Remember to dispose of trash responsibly.
4. Support Local Conservation Efforts
Local communities in the Banda Islands and Maluku Islands are actively involved in various marine conservation efforts, and if you are interested, you are welcome to join and support them, whether by volunteering or donating. Additionally, you can also book liveaboards and dive trips with companies that adhere to sustainable practices and support marine conservation programs.
