Siem Reap to Sihanoukville Night Sleeping Bus 2026-2027: Ultimate Top-Bunk Pickup Plan with Tuk-Tuk Handoff | Journey Cambodia
Skip the 11-hour daytime bus. Sleep through it. Wake on the Sihanoukville coast by 8 AM, hit the Koh Rong ferry pier before lunch, single verified $34 sleeper, blankets and water already on your bunk.
Giant Ibis sleeper coach, AC cabin, onboard toilet, 1.8-meter bunks, bottled water, cold towel, blanket, pillow, power outlets at every bunk, reading lights on the top tier, and two to three driver-swap stops. Pickup behind Old Stadium on Khmer Pub Street. Drop-off on Phe Street, Sangkat 3, next to the Autonomous Port.
If you are staring at 510 to 525 km of road between the temples of Siem Reap and the southern beaches of Sihanoukville, and the thought of an eleven-hour day bus is what kills your plan, you are the everyday rider I write this for.
The proven overnight sleeper coach pulls out of the Giant Ibis Siem Reap Bus Terminal at 10:00 PM with onboard toilet, blankets, water, towel, and power outlets at every bunk, then drops you at the Sihanoukville Ticket Office on Phe Street by 8:00 AM for $34.
Want me to lock tonight’s sleeper for two and flag the top-bunk window with the reading lights before anyone else grabs it?
And just so you know my bias up front. I have ridden the day bus out of Siem Reap twice. The heat, the stops, the way a seven-hour day bus eats a real afternoon… it wore me down. So when friends and readers ask how to bridge the two halves of Cambodia by sleeper, my answer is the same: the Siem Reap to Sihanoukville Night Sleeping Bus runs almost every night, the bunk with the reading lamp is the secret weapon, and the morning drop-off sits one tuk-tuk hop away from the ferry pier.
This page walks you through booking, pickup, the bunk choice, the overnight ride, the morning drop-off, and the tuk-tuk handoff to the ferry pier. I pieced it together from my own trips, recent Giant Ibis confirmations, and the booking card each coach publishes. A few figures sit in a range (510 to 525 km, 10 to 11 hours), and I will flag those in the Key Details section so nothing surprises you on the highway.

READY TO BOOK?
So there you go. The overnight sleeper coach out of Siem Reap is not a glamorous ride, but it is the cleanest handoff between the temples and the southern coast. You save an entire daylight day, your wallet stays at a $34 verified fare, and you wake close to the ferry pier ready for the morning boat. If you travel with family or a partner, lock in top bunks first and grab the reading lamps before anyone else. Anyone telling you to take a 7:00 AM day bus has probably never slept through Highway 6. Lock your sleeper tonight and I will keep the booking on file with a verified voucher.
