Best Siem Reap to Sihanoukville 2026-2027 Sleeping Bus

Save daylight hours, skip a day of buses, and wake up ready for the coast along Cambodia’s most-used overnight route.

The proven Siem Reap to Sihanoukville Night Sleeping Bus works like this: board around 10:00 PM in Siem Reap, sleep through roughly 510 to 525 km of Highway 6, and step off in Sihanoukville near 8:00 AM. You skip an entire day of grinding road time, with onboard toilets, blankets, cold towels, and bottled water all included. Most buses leave each night, with fares that typically sit near $34 for a single lower bunk. Top bunks hold the reading lights and the power outlets, so lock those early. Tuk-tuks wait outside the Sihanoukville office for the run to the Koh Rong ferry pier.

If you’re staring at 525 km of road between temples and coast, and the thought of an 11-hour day bus makes you cancel the Sihanoukville plan, you’re not alone.

The Siem Reap to Sihanoukville Night Sleeping Bus rolls out of Siem Reap at 10:00 PM with onboard toilet, blankets, water, and power outlets at every bunk, then drops you near the Sihanoukville Autonomous Port by 8:00 AM for $34.

Curious which departure matches tomorrow’s Koh Rong ferry pier check-in?

Pick Up and Drop Off Service

No pickup on the night run. Terminal start, terminal end. Tuk-tuks line up at both ends.

Pick Up — Siem Reap

• Not included. Complimentary pickup service is currently not available for night bus departures on the Siem Reap to Sihanoukville route. Same rule as other Giant Ibis night corridors out of Siem Reap.
• Meeting point: Giant Ibis Bus Terminal, Behind Old Stadium, Khmer Pub Street, Siem Reap.
• Arrival window: Be at the terminal by 21:40 for a 22:00 departure. The Crew Attendant releases bunk assignments at boarding.
• Contact before you go: Terminal phone +855 96 999 3333. WhatsApp or call if your tuk-tuk driver is late.
• From your hotel? Tuk-tuks from central Siem Reap to the terminal run about $3 to $5. Budget 10 to 15 minutes from Pub Street-area hotels. Driver lounge is small, no seats to spare.
• From the airport? Reputable taxi or tuk-tuk runs $7 to $10. Allow 45 minutes and confirm the terminal name before you ride off.

Drop Off — Sihanoukville

• End point: Giant Ibis Ticket Office, Phe Street, Sangkat 3, Sihanoukville (next to the Sihanoukville Autonomous Port).
• Arrive: Roughly 08:00 AM. Step off, collect your daypack, and the tuk-tuk queue is already outside.
• No shuttle, but drivers hover. Once you receive your baggage there are usually several tuk-tuks waiting for the run into town.
• Onward pricing (typical):
  • Downtown Sihanoukville / Serendipity Beach area: short hop, about $2 to $5 by tuk-tuk.
  • Otres Beach: about 7 km south of town. Tuk-tuks typically run around $3 to $5. Negotiate the return too.
  • Koh Rong ferry pier: about 37 km of road from the office (23 miles). Allow 60 to 90 minutes by car or shared minivan.
• Booking onward rides: Cash in small USD notes gets you a faster answer than app-hailing. Drivers prefer it.

What This Means For You

• Plan your own pickup. A $3 to $5 tuk-tuk to the terminal at 21:40 is the cleanest play.
• Don’t trust the small bus terminal lounge. The arrival point in Sihanoukville is small, with very little seating. Move quickly through the office to skip the queue.
• Book the ferry or any onward minivan in advance. Sihanoukville to Koh Rong ferries run about 45 to 90 minutes depending on boat. Buy the day ticket the night before if you can.
• Confirm at booking. Pickup and drop-off streets rarely change, but tuk-tuk rates drift by season. Re-check on the day.

Best Siem Reap to Sihanoukville 2026-2027 Sleeping Bus

So there you have it. The Siem Reap to Sihanoukville Night Sleeping Bus works. It is not glamorous. The bunks are firm, the AC blows cold, and the highway noise sneaks through the rubber window seals. But you wake up having saved an entire day, your wallet has not taken a tour-bus-sized hit, and you are standing near the Sihanoukville Autonomous Port ready to hit the Koh Rong ferry pier by 9 AM.

If you are booking for a family or a partner, lock in the top bunks first. Reading lights, quieter aisle, and an extra inch of mattress space pay off after hour six. And yes, you can do this on a single credit card, online, the night before. Anyone telling you to take the day bus has probably never slept through the Cambodian overnight bus Cambodia open road.
