Banda Sea Diving

Diving in Banda Sea
Schooling Hammerheads, Active Volcanos, Whales and Sea Snakes!

What more could you ask for on a dive vacation? The Banda Sea is in the heart of Indonesia and a major freeway for blue whales, dolphins, schooling hammerheads and other pelagics. Covering nearly 200,000 sq.mi. from Timor to West Papua, Banda Sea itineraries go by several names including the Forgotten Islands, the Ring of Fire, Spice Islands and the Banda Islands. The Banda Sea is what liveaboard diving is all about. With dive sites only accessible by liveaboard, pelagics and macro life, historical and cultural shore excursions, you couldn’t ask for much more.

What is the diving like in Banda Sea?

Hydrothermal vents, deep wall dives, pinnacles, seamounts, muck dives and shallow patch coral reefs make up the dive sites in the Banda Sea. The Banda Sea is like the beating heart of Indonesia’s marine life. It is the waterway connecting the Indian and Pacific Ocean and a major migration path for cetaceans. Wall dives here are covered in soft corals and barrel sponges large enough to sit in (not recommended). Hydrothermal vents lure sea snakes (kraits) to Manuk Island also known as Snake Island for their abundance in the waters here. 

Best time of year to dive Banda Sea - Water Temperatures

The Banda Sea is typically offered as a transition trip when liveaboards relocate from Komodo to Raja Ampat. Summer months (June-August) bring more rainfall and a bit rougher seas. The rest of the year conditions remain relatively constant but access to diving can be restricted to when liveaboards are operating here. 

Best time to travel: March-April & September-November

Water Temperatures: 79-84° (26-29) Year-round

Visibility: 50-100 ft. (15-30m)

Experience Level: Recommended for advanced divers due to a number of sites having higher current or deeper sites when looking for hammerheads. 

The Best Way to Experience Diving in the Banda Sea and Forgotten Islands?

The best and only way to experience all the Banda Sea has to offer is by dive liveaboard. Traveling from Komodo to Ambon would cover over 1,000 mi and take the average liveaboard 4-5 days of straight travel time. Liveaboards often offer trips from Komodo to Maumere or Alor and then Alor to Ambon. 

Not only does the Banda Sea offer spectacular diving but the topside excursions are spectacular as well. When booking a liveaboard to Banda Sea take the following into consideration: 

  • The faster your boat, the less time you spend in transit and more time you can spend diving or exploring topside
  • Book a liveaboard that will offer multiple excursions (Fort Belgica is a historical and interesting stopping point)
  • Stability is valued on these transit trips as seas can get choppy. Larger liveaboards and a wider beam generally result in a more stable ride.

Top Dive Sites of the Banda Sea

Divers have only scratched the surface of opportunities within the Banda Sea. Due to the shorter season and great distances to travel most liveaboards have yet to truly explore these waters. The following regions describe the different styles of dives offered in each area:

In addition to the muck diving there are also spectacular seamounts, pinnacles reefs, wall and caves.

Banda Islands

Banda Islands, also known as the Spice Islands, are comprised of Banda Neira, Banda Besar and Banda Api along with many other smaller islands. Lava flows from the islands have created volcanic reefs that are lush with soft corals and teeming with fish life. The deeper walls here offer a great chance to spot schooling hammerheads and grey reef sharks. Shallower sites are full of macro-life including the mandarin fish. While you’re here be sure to visit Belgica Fort or a nutmeg plantation. Other excursions include visiting a maritime and cultural museum or local markets. 

Manuk Island

Manuk Island is best known for the abundance of sea snakes here, lending its other name of Snake Island. The Banded Sea Kraits are attracted to the geothermal vents here. Manuk Island is also a bird sanctuary for frigates, boobies, gannets and more.

Pantar Strait and Alor

Pantar Strait and Alor are located to the southwest and close to the flowing waters from the Indian Ocean bringing in nutrient rich waters. 


Dive sites here offer incredible variety for both megafauna and macro. Pelagics here include schooling hammerheads, thresher sharks, reef sharks and mola mola.

Topside Excursions in Banda Sea

The question to ask yourself is not what do I get to see when exploring the Banda Sea, but what do I want to see? How many dives is your group willing to give up in exchange for the incredible excursions available on land?

When going on a dive vacation that is certainly going to be your focus, but it’s also important to take a moment and immerse yourself in the beauty and history of wherever you are visiting. The Banda Sea was one of the most important regions in the spice trade with countries like Portugal and the Netherlands fighting many battles over the riches here. Until the 1800’s the Banda Islands were the only location in the world where nutmeg was grown. 

The following are some of our favorite topside excursions in the Banda Sea:

Fort Belgica & Gunung Api

Fort Belgica is a 17th century Dutch fort which used to be home to nearly 400 soldiers and 50 cannons. It has been fully restored and is open to the public. Gunung Api is an active volcano that acts as a backdrop to Fort Belgica. Hikes can be arranged to explore around the base of the volcano.

Banda Neira - Nutmeg Plantation

Visit a Nutmeg Plantation in the Banda Islands. For centuries countries fought over these islands as they were the only location in the world where nutmeg was grown. The fertile soil in these islands allows them to grow a variety of spices and produce for export.
