The Banda Sea crossing is a one-way passage — usually Sorong to Ambon, 11–14 nights — that pairs Raja Ampat’s reefs with the Banda Sea’s volcanic walls and sea snakes. It runs only in narrow transition windows each year, and it is the most exposed itinerary in the region.

Why does this itinerary only run twice a year?
Because it is a repositioning trip. Raja Ampat’s liveaboard season runs October to April; in May–September most vessels move to Komodo or the Banda Sea. Rather than sail the transit empty, operators sell it as an expedition. That is genuinely good value for divers — you are crossing water that nobody visits for its own sake — but it also means the departures are fixed, few and one-way.
| Nights | Leg | Typical sites and activities | Dives (range) |
|---|---|---|---|
| Nights 1–4 | Raja Ampat — Dampier Strait and Misool | Cape Kri, Blue Magic, Magic Mountain, Boo Windows | 10–14 |
| Nights 5–6 | Open-water passage south-east | One dive if timing allows; blue-water day | 0–2 |
| Nights 7–10 | Banda Sea — Koon, Nusa Laut, Manuk, Serua | Volcanic walls, sea kraits, black sand, big blue | 10–14 |
| Nights 11–12 | Banda Neira and the nutmeg islands | Lava flow coral, historic fort, village walk | 4–6 |
| Nights 13–14 | Passage to Ambon | Muck diving in Ambon Bay, then no-fly day | 2–4 |
Itineraries vary between vessels and are reordered constantly for weather. Treat any published day-by-day plan for this route as an intention rather than a contract — and be glad, because a crew that refuses to change plan in the Banda Sea is a crew to avoid.
How does it differ from a standard Raja Ampat trip?
Three ways. First, the dive count per day falls: passage days carry one dive or none, so the total across two weeks is roughly 25–35 rather than the 30–40+ of a grand expedition inside Raja Ampat. Second, the character of the diving changes — the Banda Sea is oceanic, with deep walls dropping into blue rather than the reef slopes and channels of Raja Ampat. Third, the sea state is in a different category entirely.
How rough is it, honestly?
This is the itinerary where we turn people away. There are passages of a full day and night in open ocean with real swell, out of sight of land, on a vessel that rolls. Most guests adapt within 24 hours; a minority do not, and being unwell for two of your fourteen nights is a different proposition from being unwell for two hours.
If you have been badly seasick before, take the sheltered Dampier Strait route instead. If you are unsure, start medication the evening before each passage, sleep low and amidships, and stay on deck in daylight. And note that at the most remote points of this route you are many hours from a port and the nearest recompression chamber — conservative profiles and current dive accident insurance are not optional here.
How do you plan flights for a one-way itinerary?
Sorong’s Domine Eduard Osok airport (SOQ, often written DEO) is the northern gateway; Ambon’s Pattimura airport (AMQ) is the southern one. Both connect through Jakarta or Makassar — roughly 4–4.5 hours Jakarta to Sorong and 2–2.5 hours Makassar to Sorong on the airlines currently serving the route. Schedules change often, so check before you commit.
Two rules: arrive a night early at the embarkation port, and do not book a same-day connection out of the disembarkation port. The final day of the cruise carries no diving in order to respect the 18-hour no-fly interval, and that interval is the reason, not a formality.
What does the crossing cost?
| Cabin standard | Per person, per night | 11 nights | 13 nights | 14 nights |
|---|---|---|---|---|
| Value / simpler vessel | USD 250–350 | USD 2,750–3,850 | USD 3,250–4,550 | USD 3,500–4,900 |
| Mid-range ensuite twin | USD 350–500 | USD 3,850–5,500 | USD 4,550–6,500 | USD 4,900–7,000 |
| Premium double / deluxe | USD 500–650 | USD 5,500–7,150 | USD 6,500–8,450 | USD 7,000–9,100 |
| Ultra-luxury / master cabin | USD 650–800+ | USD 7,150–8,800+ | USD 8,450–10,400+ | USD 9,100–11,200+ |
Rates are indicative market bands for the 2026–2027 season, quoted per person in USD on a shared twin basis unless stated. They move with vessel, cabin, season and group size, and they change — ask us for the live rate on your dates before you plan a budget around them.
Budget separately for two one-way domestic flights rather than a return, which typically costs more than a round trip to a single city, and for an extra hotel night at each end.

Which Raja Ampat fees are not included in the trip price?
Two separate government charges apply in Raja Ampat, and most websites merge them into one wrong number. They are collected by different bodies, cost different amounts and have different validity. Budget for both.
| Charge | Who collects it | Foreign visitor | Indonesian visitor | Validity |
|---|---|---|---|---|
| Marine park conservation card (the “PIN card”) | Raja Ampat Marine Park Authority, under West Papua Governor’s Regulation No. 4 of 2019 | IDR 700,000 | IDR 425,000 | 12 months from purchase; children under 12 exempt |
| Visitor entry ticket | Raja Ampat Regency, paid through the SIPARI platform | IDR 1,000,000 | IDR 300,000 | Per visit, in force since 1 January 2026 |
Neither charge is normally inside a liveaboard fare. Your crew will usually arrange the conservation card on your behalf at the start of the trip and add it to your onboard bill. Fees are set by government and can be revised — confirm the current amounts with us before you travel.
What is included in the fare, and what is not?
| Normally included | Normally extra |
|---|---|
| Cabin accommodation for the full charter | Marine park conservation card (IDR 700,000 foreign) |
| All meals, snacks, soft drinks, tea and coffee | Regency visitor entry ticket (IDR 1,000,000 foreign) |
| Guided dives as per the itinerary, tanks and weights | Nitrox fills and dive courses |
| Dive guides, cruise director and full crew | Equipment rental if you do not bring your own |
| Tenders, kayaks and snorkelling gear | Alcohol and premium drinks |
| Group transfers on embarkation and disembarkation day | Flights, pre- and post-trip hotels, dive insurance, crew tips |
Inclusions vary slightly between vessels. We send you the exact line-by-line list for the boat you are considering before you pay anything.
What makes a Raja Ampat liveaboard genuinely low-impact?
“Eco” on a boat is a set of habits, not a wooden hull. A traditional phinisi is built by hand from dense tropical hardwood at Tana Beru and Bira in South Sulawesi — a craft inscribed on the UNESCO Intangible Cultural Heritage list in 2017 — and its genuine advantage is a long hull life that can be repaired locally. That is a real argument. It is not, on its own, a sustainability claim.
The practices that actually change a boat’s footprint are these: a reverse-osmosis watermaker instead of crates of bottled water, solar and battery capacity that cuts generator hours at anchor, no single-use plastic aboard, a reef-safe sunscreen briefing on day one, mooring buoys or sand-anchoring only — anchoring on coral is prohibited inside the marine protected area — sorted waste carried back to shore rather than burnt or dumped, holding tanks that are never discharged near a reef, and a Papuan and Indonesian crew paid properly. Ask any operator, including us, to answer those eight points specifically. Vague language is the tell.
Who is this for?
It suits divers with 50+ logged dives who are comfortable in blue water and current, travellers who have already dived Raja Ampat and want something almost nobody has, and anyone who values a genuine expedition over a comfortable schedule. Photographers should read the photography liveaboard page before choosing a lens strategy for a two-region trip.
It does not suit newer divers, anyone prone to seasickness, families with children, or travellers who need a fixed itinerary. If you want remoteness without the ocean crossings, the Triton Bay expedition is the gentler alternative.
Frequently asked questions
What is the Banda Sea crossing?
A one-way liveaboard passage, usually Sorong to Ambon, of roughly 11-14 nights, that combines Raja Ampat’s reefs with the volcanic walls, sea snakes and hammerhead chances of the Banda Sea. It is a repositioning itinerary, which is why it runs only in narrow windows.
When does it run?
In the transition periods at each end of the Raja Ampat season – broadly around March-April and again around September-October – when vessels move between their Raja Ampat and Komodo or Banda programmes. Only a handful of departures exist across the whole fleet each year.
How rough is it?
This is the most exposed itinerary offered in the region. There are long open-water passages of a full day or more with genuine ocean swell. If you have been seasick on a short crossing before, this is not the trip to test yourself on.
How many dives will I get?
Fewer per day than on a pure Raja Ampat trip – typically 25-35 across 11-14 nights, because passage days may carry only one dive or none. What you gain is access to sites almost nobody dives.
What will I see in the Banda Sea that I will not see in Raja Ampat?
Steep volcanic walls, extraordinary hard coral on black sand, huge congregations of banded sea kraits at some sites, and, in season, schooling hammerheads at a few offshore locations. Sightings are never guaranteed.
How do I plan flights for a one-way trip?
Fly into Sorong (SOQ) and out of Ambon (AMQ), or the reverse depending on direction. Both connect through Jakarta or Makassar. Book the two legs on a single ticket where you can, and always allow a buffer night at each end.
Do the Raja Ampat fees still apply?
Yes, for the Raja Ampat leg. The marine park conservation card at IDR 700,000 for foreign visitors and the regency visitor entry ticket at IDR 1,000,000 both apply. Banda-area arrangements are handled separately by the vessel.
Who should not book this trip?
Anyone with fewer than about 50 logged dives, anyone prone to motion sickness, and anyone who needs certainty – weather reroutes are common on this itinerary and the crew will change the plan to keep the boat and the guests safe.
How do you book this trip?
Crossings sell out a year ahead because there are so few of them. Send us your travel window, your certification level and how many people are in your party on WhatsApp +62 811 3823 875 or by email at [email protected]. We reply with the vessels available for those dates, the cabin-by-cabin rate, the deposit terms and a plain list of what is not in the price. There is no obligation and no deposit until you have seen the boat and the itinerary in writing.
