The Banda Sea is where adventure, history, and raw beauty collide. Known as the “Spice Islands,” this remote corner of Indonesia offers a rare mix of world-class diving and centuries-old heritage.
From hammerhead shark encounters and technicolor coral gardens to sunset dives with mandarin fish, every day here is extraordinary. Above the surface, ancient forts, spice plantations, and volcanic landscapes reveal a story of global trade and cultural fusion.
Calico Jack and Anne Bonny are among the few yachts equipped, and experienced, enough to reach these remote islands safely and in comfort. Every October, when the winds allow, our vessels cross open waters to deliver unrivaled Banda Sea expeditions, combining thrilling dives with immersive cultural exploration. Whether you’re chasing schooling hammerheads, diving WWII wrecks, or wandering spice markets, this is Indonesia at its most unforgettable.

Experiences in the Spice Islands and Banda Sea
The Banda Sea is a stunning underwater realm, offering a breathtaking landscape both above and below the water. From its vibrant coral reefs and rich marine biodiversity to the historical significance of the Banda Islands, there’s something for every explorer. The area has a rich history, once a center for spice trade, that continues to captivate adventurers today.
Diving in the Banda Sea and the Spice Islands
Located in the deep waters between Indonesia’s islands, this region is shaped by oceanic currents and open-sea conditions, attracting pelagic species and creating some of the most exhilarating dives in the country.
For a short window each year, divers have the opportunity to explore these rarely visited reefs, and encounter one of the ocean’s most iconic spectacles: schooling hammerhead sharks.
Hammerhead Shark Encounters
During October crossings, large schools can be seen cruising along steep drop-offs and seamounts, a rare and unforgettable experience.
Pristine, Untouched Reefs
Due to its remoteness and limited access, reefs are exceptionally healthy, with vibrant coral coverage, large schools of fish, and minimal diving pressure.
Deep Ocean Diving
Unlike the protected reefs of Raja Ampat, many Banda Sea dive sites rise from deep ocean waters, creating dramatic underwater topography and attracting pelagic species.
Rare & Seasonal Opportunity
Diving in the Banda Sea is only possible during a short seasonal window when conditions allow vessels to safely cross open waters.
Dive Conditions
Diving in the Banda Sea is generally best suited to experienced divers.
• Water temperature: 26–28°C
• Visibility: often excellent, 20–30m+
• Conditions: can be exposed with currents and swell
• Experience level: intermediate to advanced
When to Visit the Banda Sea
Unlike destinations that can be visited year-round, Banda Sea expeditions are limited to just a few departures each season.
For many divers, this is a once-in-a-lifetime journey, combining remote ocean crossings, historic islands, and the chance to encounter schooling hammerhead sharks.
Calico Jack expeditions take place during October and early November, when changing winds create the conditions needed to safely cross these open waters and explore the region.

October – Early November
This brief seasonal window offers the best opportunity to explore the Banda Sea.
During this time:
- Winds begin to shift, allowing safe crossings between remote islands
- Sea conditions become more stable across open water
- Visibility is typically excellent
- Pelagic activity increases, including the chance of hammerhead shark encounters
Banda Sea Off Season
Outside of this window, the Banda Sea is largely inaccessible to liveaboards due to strong winds, swell, and open ocean exposure.
This makes the October crossings particularly special, a short-lived opportunity to explore one of Indonesia’s most remote and least-visited regions, that happens to coincide with one of natures great migrations.

Beyond Diving in Banda
Banda Neira is one of the last resorts of untouched history. Here, for three centuries, some of the most powerful countries tried to establish their domination over the spice trade. This history remains in the architecture of the forts, houses, and household items. Visiting Banda Islands will leave you wondering about the major events that happened in this remote location.
Kayaking amongst the carst lagoons of the Misool archipelago is another fantastic activity to engage in. We can also set up a beach hang-out to spend a lazy day under the umbrella. So, if you (or your partner) are not a diver, there are still plenty of exciting things to do on the Banda Neira cruise!
Visitors Neira can enjoy a variety of inland activities that enhance their understanding of the island’s cultural heritage and natural beauty:
Historical Tours: Explore the remnants of Banda Neira’s colonial past, including Fort Belgica, which offers panoramic views, and other historical spice trade sites.
Nature Walks and Hiking: Discover the island’s lush landscapes through hiking trails, including one that leads to the summit of a nearby sleeping volcano.
Spice Plantations: Visit local spice plantations to learn about nutmeg, cloves, and the role these products played in the island’s history.
Birdwatching: Join birdwatching tours to spot a variety of species, including Wilson’s bird of paradise.
Beach Activities: Relax on tranquil beaches, perfect for beachcombing or picnicking.
Kayaking: Paddle through the serene waters, exploring hidden coves, mangroves, and deserted beaches for a unique perspective on the region’s beauty.
Community Engagement: Participate in local initiatives by helping schools or clinics, and consider bringing school or medical supplies to foster goodwill.
These inland activities complement the exceptional diving experiences in Banda Neira, providing a well-rounded adventure filled with cultural insights and stunning scenery.
Raja Ampat – Banda Neira cruise starts from Sorong and finishes in Ambon, a city in the Maluku Islands that can be reached via flights from Jakarta, Bali, or Makassar. The reverse, Banda Neira – Raja Ampat cruise starts from Ambon and finishes in Sorong. We suggest choosing Garuda Indonesia for your domestic flights, but other carriers are also acceptable. It’s advisable to book your flights in advance, especially during peak seasons.
Our driver will pick you up from the airport or the hotel on the first day of the cruise. The hotel pick-up is usually between 9 and 9:30 am. We will drop you off at the airport or the hotel on the last day of the cruise. They will assist you with your luggage and transfer.
The boat will leave the harbour at 11 a.m. All guests are required to be on board before 10 a.m. For the remote areas like this, we advise arriving one day in advance to be on time for the cruise and to get some rest after the long travel.
Our last dive will be at 12 p.m. on the day before last. We will arrive at the harbour in the late light of the day before the last. The departure from the boat is planned for after breakfast (around 11 a.m.). Yet, if you need to take an early morning flight, we can drop you off any morning. However, for the early departures, please mind that you will need to skip the last dive at noon of the previous day.
