Chart 02 — Why the strait
The Pantar Strait funnels open-ocean water between Alor and Pantar in Indonesia’s Lesser Sunda chain, driving currents of up to 5 knots through channels that feed some of the richest reefs in the Coral Triangle. The Selat Pantar Marine Protected Area covers these waters, and the neighbouring Ombai Strait is a deep-water migration corridor for whales and dolphins.
The diving is genuinely expedition-grade: the seamount at Kal’s Dream, the drift along the Great Wall of Pantar, anemone fields at Clown Valley, and black-sand muck bays at Beangabang and Kalabahi where Rhinopias are found more reliably than almost anywhere in Indonesia. From August to November, scalloped hammerheads school in the channels, with mola-mola and thresher sharks as the cold-water bonus when thermoclines rise.
Expeditions run aboard traditional phinisi with 10–20 guests, 3–4 guided dives a day including night dives, out of the gateway port of Kalabahi. Water holds 26–29°C year-round; visibility routinely exceeds 30 m at the July–September peak.
| Route | Nights | Signature | Window |
|---|---|---|---|
| Alor-only loop | 3–7 | Walls, muck bays, hammerhead channels | Apr–Nov |
| Maumere → Alor | 7+ | Flores volcanoes, remote reefs en route | Apr–Nov |
| Banda Sea crossing | 12–15 | Open-ocean hammerhead seamounts | mid-Sep–mid-Nov · Mar–Apr |

Chart 04 — Season log
Apr — Jun
Seas calm, visibility climbs to 20–25 m, macro thrives — shoulder pricing up to 15% below peak.
Jul — Sep
30 m+ visibility, strongest currents, highest odds of hammerheads, threshers and mola-mola.
Oct — Nov
Visibility holds above 25 m, gentler currents, prime Rhinopias and frogfish hunting.
Dec — Mar
Wet-season swell; most vessels reposition — the Mar–Apr Banda shoulder reopens the crossings.
Chart 05 — Field questions
Advanced Open Water (or equivalent) is the working standard — Alor’s channel dives run in current, and operators typically ask for a minimum number of logged dives. Confirm your logbook status when booking; the safety guide covers requirements in detail.
April to November, the dry season. July–September peaks with 30 m+ visibility and the strongest pelagic action; August–November is the hammerhead window; October–November favours macro. Full month-by-month detail in the best-time guide.
From roughly $4,000 per person for a 7-day expedition, $5,500–8,000 mid-range, and $8,000–12,000+ on ultra-premium vessels. Nitrox, gear rental and crew gratuities are the usual add-ons — see the cost guide.
A 20–30% deposit confirms your cabin, with the balance due 60–90 days before departure. July–September departures are best booked 9–12 months ahead. The booking guide walks through every step.
An Alor-only loop through the Pantar Strait (5–7 nights) covers the signature walls, muck bays and hammerhead channels without a long open-water crossing. The routes guide compares every itinerary family.
Yes — the Pantar Strait has world-class snorkeling over shallow reef, and village visits to Takpala, Pura and Ternate fill surface time. The snorkeling guide sets honest expectations.
