To get from Sorong to Waisai, take the Express Bahari fast ferry from Sorong’s public harbour (Pelabuhan Rakyat). The crossing takes about two hours. As of 2026 there is a 14:00 sailing every day, plus a 09:00 sailing on some days. Private speedboats are quicker but cost much more. The ASDP car ferry takes around five hours.
If you’ve booked Raja Ampat day dive tours out of Waisai, your first dive depends on which boat you catch and when you land at Domine Eduard Osok airport (SOQ). Treat every time and price below as a 2026 snapshot and confirm at booking.
What are the ways to cross from Sorong to Waisai?
You have three realistic options, and they suit different travellers.
| Option | Crossing time | Comfort | When to choose it |
|---|---|---|---|
| Express Bahari public fast ferry | About 2 hours in calm seas | Economy seating or an air-conditioned VIP cabin | Most divers, most days. Cheap and frequent enough if you land before midday |
| ASDP car ferry (KMP Arar, KMP Lema) | Around 5 hours | Basic deck seating, slow | Only when it fits your date, or if you’re moving a vehicle or lots of cargo. It doesn’t run daily |
| Private speedboat charter | Usually shorter than the fast ferry, depending on sea state | Private, but you feel every wave | Late arrivals, big groups with gear, or tight connections. Priced per boat on request |
PT Belibis Papua Mandiri operates Express Bahari. ASDP’s 2026 timetables for KMP Arar show sailings roughly once a week; the 15 May sailing left Sorong at 14:00 and reached Waisai at 19:00. Useful as a backup, not as a dive-trip plan.
When do the ferries leave Sorong, and what do tickets cost?
The 14:00 sailing is the one every source agrees on. The morning boat is less certain:
- Seasonal pattern: A timetable guide updated in August 2026 lists 09:00 and 14:00 on Wednesday, Friday and Sunday during the November-April rotation, with 14:00 only on other days and outside that rotation.
- Daily pattern: Stay Raja Ampat’s travel guide lists 09:00 and 14:00 in both directions daily, with only the 14:00 boat on public holidays.
- Fares: Published fare quotes differ between sources, so check the current fare at the harbour counter.
There’s no online booking as of 2026; tickets are sold at the harbour counter on the day. Carry rupiah even though card and QRIS are reported to work. From October to April, arrive 1 to 2 hours early, because seats sell out.
What if your flight lands too late for the ferry?
Allow time for baggage, the drive from SOQ to the harbour, and the ticket queue. Here’s how landing times translate into same-day crossings:
| Flight lands at SOQ (local time) | Same-day crossing? | What to do |
|---|---|---|
| Before 07:45 | Possible on 09:00 days | Go straight to the harbour. It’s tight if bags are slow |
| 08:00-11:30 | Yes, on the 14:00 ferry | The most reliable window. Buy your ticket as soon as you arrive |
| 11:30-12:30 | Risky | In peak season the ferry may be full. Have a speedboat on standby |
| 12:30-15:00 | Not by public ferry | Private speedboat in daylight, or stay overnight in Sorong |
| After 15:00 | No | Stay in Sorong and take the next morning or afternoon sailing |
Coming from Komodo? Labuan Bajo to Sorong takes about 3.5 hours with connections, so on a 5-day Komodo plus 7-10-day Raja Ampat routing, a night in Sorong is often the calmer choice. Don’t plan to cross after dark; most boat operators won’t.
How do you handle luggage and dive gear on the crossing?
Express Bahari puts large dive bags and suitcases in the cargo area, so pack with the hold in mind:
- Carry-on: Keep your dive computer, regulator, torch batteries, medication, cash and certification card with you.
- Checked bags: Use soft dive bags with a waterproof liner. Luggage in the hold can pick up spray and bilge water.
- Porters: Agree a small tip up front and watch your bags go into the hold.
- Cabin choice: The air-conditioned VIP cabin has its own toilet, which matters in June-September chop.
Where are the marine park card and regency ticket checked?
From 1 January 2026, every visitor pays two separate charges, diver or not, even on a day trip:
- Marine park conservation card, run by the Raja Ampat Marine Park Authority. The Raja Ampat marine park fee for foreign tourists is IDR 1,000,000 per person per year, with children under 12 exempt, under Southwest Papua Governor Regulation No. 32 of 2024, as listed by the Raja Ampat MPA Management Authority (checked 2026-09-16). The Raja Ampat marine park fee for Indonesian tourists is IDR 500,000 per person per year, or IDR 250,000 for Papua-area ID holders from outside Southwest Papua and IDR 150,000 for Southwest Papua ID holders, under Southwest Papua Governor Regulation No. 32 of 2024, as listed by the Raja Ampat MPA Management Authority (checked 2026-09-16).
- Raja Ampat Regency entry ticket, under Regent Regulation 34/2025. It is charged per visit and covers one trip only; confirm the current rate at booking.
Waisai harbour is the first checkpoint: tourism and park desks there sell or check the documents, homestays and dive centres ask to see them, and park patrols can check cards at dive sites. Operators usually process permits in advance, and liveaboards typically bill the fees separately. Carry the card, or a clear photo of it.
How is a day dive tour timed around the crossing?
Plan the crossing as its own day:
- Day 0: Land at SOQ in the morning, take the 14:00 ferry and reach Waisai around 16:00. Check your gear and do paperwork in the evening.
- Day 1 onward: Leave early for the Dampier Strait. Cape Kri and Blue Magic are Advanced Open Water territory; Open Water divers generally stay at 18-20 m on calmer reefs near Waisai.
- Last dive: Finish at least 18 hours before your flight, in line with Divers Alert Network guidance for repeat dives.
- Return: Take the ferry back to Sorong and fly out the next day, or catch a morning sailing if you’re booked on a late afternoon flight.
From October to April the Dampier Strait usually sits at Beaufort 1-3; July to September brings wind and swell that make the crossing harder to time. Komodo Luxury recommends October to April and builds dive schedules around the ferry, with dives guided by licensed partner dive centres.
Frequently Asked Questions
Can I buy a Sorong to Waisai ferry ticket online?
No, not as of 2026. Express Bahari tickets are sold only at the harbour counters in Sorong and Waisai on the day you travel. Some local contacts take WhatsApp reservations, but you still pay in person. During the October-April dive season, arrive one to two hours before the 14:00 sailing, because economy and VIP seats can sell out.
Is the Sorong to Waisai crossing rough enough to cause seasickness?
It depends on the month. From October to April the Dampier Strait is usually calm, and the two-hour crossing is comfortable for most people. From June to September, wind and swell are stronger, and the ride can be choppy. If you’re prone to seasickness, book the VIP cabin, sit toward the middle and take medication 30-60 minutes before boarding.
Can I dive in the morning, take the ferry back and fly out of Sorong the same day?
It isn’t a good idea. The ferry itself sits at sea level, so it’s fine, but the flight is the problem. Divers Alert Network guidance is at least 12 hours after a single no-decompression dive and 18 hours after repeat dives or multiple dive days. Make your last dive the day before, then take the morning ferry with a buffer for your flight.
