Step-by-Step 2026 Arrival Timeline

How to Clear Sihanoukville (KOS) Smoothly: 6-Step Checklist

Follow this chronological sequence from pre-trip document filing through immigration clearance and onward transport.

  1. 13–5+ Days Before Your Trip

    Apply Online for Your Cambodia eVisa ($80 Tourist / $90 Business)

    Submit your passport bio page online. Because KOS has a more compact international arrivals hall than KTI or SAI, holding a pre-approved eVisa lets you bypass the manual Visa-on-Arrival cash desk and catch the afternoon Koh Rong speed ferry on time.

    Traveller Tip: No portrait photo upload or hotel reservation upload is needed when you apply through VisaToCambodia.com.
  2. 2Within 7 Days of Your International Flight to KOS

    File Your Mandatory Cambodia e-Arrival Card ($20 / $35 / $60)

    If your flight into Sihanoukville (KOS) arrives directly from outside Cambodia (such as Kuala Lumpur, Ho Chi Minh City, or regional charter hubs), you must hold a Cambodia e-Arrival QR code.

    Traveller Tip: Save your QR code offline on your phone so you can scan immediately upon walking into the terminal.
  3. 3Landing at Sihanoukville International Airport (KOS)

    Walk or Ride the Apron Bus into International Arrivals

    Located near Ream National Park 20 km east of Sihanoukville city, KOS features a streamlined ground-level arrival path. Follow the signs to International Immigration.

    Traveller Tip: Keep your printed eVisa certificate and e-Arrival QR code screenshot ready before entering the queue.
  4. 4KOS Immigration & Biometric Scan

    Present eVisa + e-Arrival QR & Receive Your Digital v-Pass

    The immigration officer scans your passport and e-Arrival QR code, verifies your eVisa, and captures your fingerprints and photo. Your official Cambodia v-Pass is emailed to you immediately.

    Traveller Tip: Confirm your v-Pass email is received — island resorts on Koh Rong and Koh Rong Samloem ask for your entry credentials at check-in.
  5. 5Baggage Claim & Customs

    Retrieve Checked Luggage & Exit Terminal

    Collect your bags from the belt and pass through customs. Your digital customs declaration is already linked to your e-Arrival QR code.

    Traveller Tip: Grab some small USD notes or local Riel at the terminal ATM before heading to the ferry pier.
  6. 6Transfer to Sihanoukville Ferry Pier or Kampot

    Connect to Koh Rong Speed Ferries or Coastal Resorts

    Take an official airport taxi or pre-booked minivan 25–35 minutes west to the Sihanoukville Autonomous Port / Serendipity Tourist Pier for high-speed catamarans to Koh Rong and Koh Rong Samloem, or head east along National Highway 3 toward Kampot and Kep.

    Traveller Tip: Most high-speed ferries to Koh Rong depart between 08:00 and 16:30 — if your flight lands late in the afternoon, book a night in Sihanoukville or Otres Beach first.
Detailed Port & Immigration Rules

Essential 2026 Guidance for Sihanoukville International Airport (KOS)

International vs Domestic Flights at Sihanoukville Airport (KOS)

Sihanoukville International Airport (IATA: KOS, ICAO: VDSV), situated in Prey Nob district adjacent to Ream National Park, serves two distinct types of travellers: passengers arriving on direct international flights from regional Asian hubs, and passengers connecting on domestic flights from Siem Reap (SAI) or Phnom Penh (KTI).

If you fly directly into KOS from abroad, KOS is your official Port of Entry into Cambodia: you will clear immigration, scan your Cambodia e-Arrival QR code, present your Cambodia eVisa, and receive your digital v-Pass at KOS. If you first land at KTI or SAI and take a domestic connecting flight to KOS, you clear immigration and scan your e-Arrival QR code at your first arrival airport (KTI or SAI).

  • Direct international flights into KOS require both a Cambodia eVisa (unless exempt) and a Cambodia e-Arrival QR code.
  • Fast clearance at KOS is critical if you are trying to make the final afternoon high-speed ferry to Koh Rong.
  • Sihanoukville connects to Phnom Penh via the modern Phnom Penh–Sihanoukville Expressway (approx. 2 hours 15 minutes by car).
Travelling from Koh Chang / Trat (Thailand) to the Cambodian Coast?The Cham Yeam / Hat Lek (Koh Kong) land border between Thailand and coastal Cambodia is closed in 2026. Travellers coming from eastern Thailand cannot cross overland into Koh Kong or Sihanoukville — you must fly into KTI, SAI, or KOS.

Connecting from KOS Airport to Koh Rong, Koh Rong Samloem & Kampot

Most leisure travellers arriving at Sihanoukville International Airport (KOS) are heading straight to the white-sand beaches of Koh Rong, the tranquil bays of Koh Rong Samloem, or the riverside pepper plantations of Kampot and coastal Kep.

Having your Cambodia Tourist eVisa ($80 USD) and e-Arrival Card QR code ($20/$35/$60 USD) completed before your flight ensures you walk out of the KOS terminal in minutes rather than waiting behind tour groups at the paper Visa-on-Arrival counter.

  • KOS to Sihanoukville Autonomous Port / Ferry Pier: 20 km (25–35 minutes by taxi, $15–$20 USD).
  • Ferry Pier to Koh Rong / Koh Rong Samloem: 40–50 minutes by high-speed catamaran.
  • KOS to Kampot Town: 85 km east via National Route 3 (approx. 1 hour 30 minutes by private taxi, $35–$45 USD).
