Leaving behind the turquoise waters and white sands of Koh Rong for the bustling border town of Krong Poi Pet marks a major transition from island relaxation to overland adventure. Most travelers making this trek are heading toward the Thai border, trading the sound of crashing waves for the neon lights of casinos and the organized chaos of one of Southeast Asia's busiest land crossings. It is a long journey that spans nearly the entire length of Cambodia, requiring a coordinated effort between sea and land transport.
Because Koh Rong is an island, your journey inevitably begins with a boat ride to the mainland, usually docking at Sihanoukville. From there, the route heads north through the heart of the country. While it is a significant distance to cover, the convenience of combined tickets allows you to transition from the ferry to a van or sleeper bus without the stress of navigating multiple booking offices. You can easily secure your spot for this long-haul trip on GoAsia.cc to ensure your connection at the pier is waiting for you.
Koh Rong to Krong Poi Pet by Ferry and Bus
The most common way to tackle this route is via a combined ferry and bus ticket. This integrated service is designed to take the guesswork out of the logistics. Your journey starts at one of the main piers on Koh Rong, where you will board a speed ferry or catamaran for the 30 to 60 minute crossing to Sihanoukville. Once on the mainland, a representative usually guides you to a waiting van or bus terminal.
Ferry and Van Combinations
For those who prefer to travel during daylight hours, the Ferry and Van option is a popular choice. These services typically depart the island in the morning or early afternoon. The total travel time ranges significantly from 9 to 19 hours, depending on the specific operator and the length of the layover in Sihanoukville or Phnom Penh. At a fixed price of $44, this represents the most budget-friendly way to reach the border. While vans are faster than large coaches, they can feel a bit cramped if fully loaded, so it is wise to keep your carry-on luggage small.
Ferry and Sleeper Bus Combinations
If you want to save on a night of accommodation and maximize your daylight hours, the Ferry plus Sleeper bus is an excellent alternative. These departures usually leave the island in the mid to late afternoon. After reaching the mainland, you will board a sleeper bus equipped with reclining berths or flat beds. This is often considered the most comfortable way to handle the 15 hour journey, as you can lie down and rest while the bus traverses the Cambodian countryside. Prices for these premium combined tickets range from $56 to $65.
Koh Rong to Krong Poi Pet by Bus
There is a specific service classified primarily as a bus option that costs $54. This route typically involves a very early morning departure from the island. With a duration of approximately 14 hours, it offers a middle ground in terms of timing and price. Travelers choosing this route should be prepared for a long day of sitting, but the benefit is arriving at the border in a single calendar day, often reaching Poipet in time for a late dinner or a rest before crossing the border the following morning.

Tips for Traveling from Koh Rong to Krong Poi Pet
- Book in Advance: This is a long and popular route for backpackers heading to Thailand. Booking a few days ahead ensures you get a sleeper berth rather than a standard seat for the overnight leg.
- Prepare for the Ferry: Sea conditions between Koh Rong and Sihanoukville can occasionally be choppy. If you are prone to motion sickness, take medication 30 minutes before boarding the boat.
- Pack Snacks and Water: While buses and vans will make pit stops at local gas stations or small restaurants, the selection can be limited. Bring enough water and some dry snacks to last the long stretches between stops.
- Keep Valuables Close: On sleeper buses, always keep your passport, phone, and wallet in a small bag that stays with you in your berth, rather than in the luggage compartment under the bus.
- Check the Drop-off Point: Poipet is a spread-out town. Some buses drop passengers near the border crossing (the "Circle"), while others stop at private terminals further out. Have your accommodation address ready for a local tuk-tuk driver if needed.
- Visa Readiness: If you are crossing into Thailand immediately upon arrival, ensure you know your visa requirements. The Poipet border can be time-consuming, so arriving well-rested is a major advantage.
