**A combination itinerary pairs Alor and Pantar’s current-swept walls with the remote Forgotten Islands arc toward Banda — usually a single liveaboard crossing in the September-October window, when boats like the Seven Seas Alor Sea trip already run this route. As of 2026 it stays a niche, experienced-diver corridor; the 2027 outlook is rising interest, not a guarantee.**
Why pair Alor with the Forgotten Islands for a 2027 shoot?
Alor and Pantar sit at the eastern edge of the Lesser Sunda Islands in East Nusa Tenggara, deep inside the Coral Triangle — an area of exceptionally high marine biodiversity. Point a boat east from Kalabahi Bay and you enter the Forgotten Islands: the thinly visited arc of volcanic specks that runs across the Banda Sea toward Banda itself.
For a photographer or filmmaker, that geography is the whole pitch. One crossing hands you three distinct visual libraries: current-driven gorgonian walls and schooling pelagics in the Pantar Strait, black-sand macro in Kalabahi Bay, and the rarely shot reefs of the Forgotten arc. Few Indonesian routes give you that much range without a flight in between.
Currentline Alor arranges these crossings strictly as an independent concierge — we curate and book through licensed, established Alor operators such as Dive Alor Dive, Nautika Dive Alor and Alami Alor rather than running boats ourselves. That keeps the focus on matching your shot list to the right vessel and the right week.
What does a combination route actually look like?
Most combination trips are liveaboard crossings, because the Forgotten Islands have almost no land-based infrastructure. An Alor-anchored leg usually starts in Kalabahi Bay — the same boarding point used by mainstream Alor Sea itineraries like the Seven Seas trip, which dives sites such as Pasir Merah, a volcanic red-sand slope with gas vents north of Pura Island.
Here is how a crossing tends to break down. Treat these as indicative planning blocks, not a fixed schedule — every operator sequences differently around weather and currents.
| Leg | Zone | Signature subjects | Photo mode |
|---|---|---|---|
| 1 | Pantar Strait | Gorgonian walls, schooling fish, mola mola, dolphins | Wide-angle |
| 2 | Kalabahi Bay | Pegasus sea moths, mimic octopus, seahorses, frogfish | Macro / muck |
| 3 | Forgotten Islands arc | Pristine reefs, gas-vent slopes like Pasir Merah | Reefscape / wide-angle |
| 4 | Banda Sea approach | Big pelagics, deep walls, occasional pilot whales | Big-animal wide-angle |
Land-based diving is realistic only for the Alor portion. One longstanding Pantar dive resort takes just 16 divers in traditional-style bungalows, runs small quiet low-emission boats, draws on its own underground water reserve, and reaches 40-plus dive sites within 30-45 minutes — a strong pre- or post-liveaboard base for macro shooters who want extra bottom time in the bay.
If the muck is your priority, note that Kalabahi Bay’s critters don’t travel far, so macro stays productive year-round. That reliability is why we often bolt a few dedicated underwater photography dive expeditions in the bay onto the front of a crossing before the boat heads east.
When should photographers and filmmakers book this crossing?
Timing is the hard constraint. The Forgotten Islands corridor is a crossing-season route, and Alor’s own best window runs April to November, with October and November bringing the most prevalent currents. As of 2026, seasonal Alor Sea liveaboards concentrate in the September-October window and board at Kalabahi Bay.
| Window | Water temp | Visibility | Good for |
|---|---|---|---|
| April | ~25 C | 25-30 m | Season opens, fewer boats |
| May-Sep | 31-32 C | Down to 15 m in plankton blooms | Warm water; September best for mola mola |
| Jun-Oct (dry) | Warm | Up to ~40 m | Wide-angle clarity in the strait |
| Oct-Nov | ~25 C | 25-30 m | Strongest currents, pelagic action |
| Nov-Mar (wet) | ~25-31 C | Reduced, unsettled surface | Weakest window for a shoot |
Rainy season roughly November to March brings unsettled surface, rain and reduced visibility, so it is the weakest stretch for filming. September is also the best month to spot mola mola, and the dry June-October run can push visibility toward 40 metres — ideal for wide-angle work in the Pantar Strait, where schooling fish, dolphins, pilot whales and occasional orcas reward a wide lens.
One honesty note that matters for filmmakers: blue-whale and hammerhead encounters must be treated as possible, not predictable. There are no fabricated peak dates. One documented scalloped-hammerhead site reaches around 32 metres in very strong current — plan it as a fitness-dependent bonus, never a guaranteed sequence.
What gear, permits, and fitness does the crossing demand?
Alor is for experienced divers, and the Forgotten Islands raise the bar again because you are far from help. Operators typically require minimum PADI Open Water for fun diving but recommend 50-100 logged dives for real comfort in the Alor-Pantar currents. All dives run no-decompression, solo diving is not allowed, and bottom time is usually capped at 60 minutes or when a diver reaches 50 bar.
Lock these before you commit:
- MPA compliance — Alor’s waters are a managed marine protected area, so every diver must attend a mandatory MPA-officer briefing, pay a marine park fee and obtain a permit before any marine activity. Guides need special MPA certification on top of standard agency cards, and diver numbers per site are capped by WWF-determined carrying capacity.
- DAN insurance — dive-accident cover is mandatory. The nearest hyperbaric chamber is in Bali, and evacuation or chamber costs are not covered by standard medical insurance.
- Currents — the Pantar Strait’s strong surface currents demand rapid descent, quick equalising and regrouping around 5 metres. Good fitness is non-negotiable on the deeper, higher-flow sites.
- Gear redundancy — carry spares. Once the boat heads into the Forgotten arc you are far from resupply.
On pricing: there are no current, citable public price tables for these crossings or the marine park fee — only that a fee and permit are required. Any figures we quote are Currentline Alor’s own indicative commercial data, dated as of 2026 and subject to change, never presented as sourced facts.
What is the honest 2027 outlook?
This is an outlook, not a prediction. Through 2026, the signals pointing toward a busier 2027 are real but modest: a fixed, weather-bound crossing window; a small fleet of liveaboards already running Alor-Pantar in September-October; and rising “last untouched gem” search interest as Alor edges toward the mainstream.
None of that guarantees more 2027 departures. Carrying-capacity caps, permit rules and the narrow season all limit how fast the corridor can grow — which is exactly why photographers and filmmakers chasing a specific vessel or week should hold their dates early rather than assume availability closer to the season.
Frequently Asked Questions
How many days do you need for an Alor and Forgotten Islands combination trip?
Most crossings run as multi-day liveaboards because the Forgotten Islands have almost no land infrastructure. Plan on a full liveaboard week at minimum to link Pantar Strait, Kalabahi Bay and the Banda-bound arc. Adding a few land-based days at a Pantar resort before boarding gives macro shooters extra Kalabahi Bay bottom time.
Can you dive Alor and the Forgotten Islands on the same liveaboard, or do you need two trips?
You can do both on one crossing. Seasonal Alor Sea liveaboards board at Kalabahi Bay and sail east through the Forgotten Islands toward Banda, so a single vessel covers the corridor. As of 2026 these run mainly in the September-October window, so book early — carrying-capacity caps and the short season limit berths.
Is the Alor to Forgotten Islands crossing suitable for beginner divers?
No. Alor alone is for experienced divers, with strong currents demanding rapid descent and regrouping near 5 metres, and operators recommend 50-100 logged dives. The Forgotten Islands add remoteness, far from the nearest chamber in Bali, and DAN dive-accident insurance is mandatory. Beginners should log more dives in calmer conditions first.
