Koh Rong to Siem Reap Destination Reviews

I got on the ferry from Koh Rong at 9am- 30 minutes early, this journey was smooth sailing and arrived onto the mainland at around 10:30. I found the booking office where I was met by the guy saying I would have to wait until 12:45 for the bus to Siem Reap- 2 hours away! There had be nothing mentioned when booking about having to wait for the buses or any timings for the day. If I had known I would have had to wait I would not have gotten a ferry so early, as no time was saved! The mini van arrived at around 12pm and the 4 of us got on it, it was comfy enough. The mini van repeatedly stopped for no reason, we picked up and dropped of random passengers throughout. We arrived into Phnom Penh at 4pm at the bus office, minimal English was spoken by the staff so I was very confused as to when the bus to Siem Reap would be considering I was meant to arrive to Siem Reap at 6:30pm. A family car then arrived to take me, the drivers were lovely but spoke no English so I was extremely confused as to why we kept on stopping and picking up/ dropping off others the whole way. At one point there were 9 people in a 7 seater car! It was definitely a unique and local experience, we stopped for food at around 9pm. We arrived into Siem Reap at 11pm, so 5 hours after the said time of arrival! I have no idea how a car was the transport to take me considering I was told it would be a sleeper bus. Just be prepared for the journey to take a lot longer than expected and feel very confused the whole time.

I booked my ticket so that I would arrive in Siem Reap for 7.30pm however when I reached my transfer in Phnom Penh they told me I would have to wait until 4.30pm for my bus meaning that I wouldn’t arrive until around 10pm. When I questioned this as there was an earlier bus leaving which would have got me to Siem Reap on time the employee just looked at me and laughed. There was no explanation as to why my arrival time was pushed back 2.5hrs and this caused a lot of stress as I was unsure if my hostel reception would still be open on my arrival. I understand that sometimes things change but to have someone laugh in my face and give no explanation was not acceptable in my eyes.

Arrived at 11.30 pm instead of 8.30pm due to waiting for a change of bus in Phnom Penh (staff were very friendly there), bus was also definitely a downgrade from the photos shown of 12togo as seats weren’t vaguely similair or comfy. Very little communication from the driver

Terrible experience. We were told the wrong pickup point for the ferry, then when we managed to get on the bus after this the driver somehow made a 5 hour drive into a 9 hour drive.

The van was way overpacked—people’s luggage had to be stacked up in the aisles. The booking also doesn’t mention that the van stops in Phnom Penh first before continuing onto Siem Reap. Seats weren’t very comfortable either.

Our ferry and bus were late and took longer than they should’ve. We arrived 5 hours later than we were meant to. The van is very cramped.

This ride was uncomfortable, poorly planned and overpacked. There was probably 20 people in a 10 seater van, someone was on a plastic chair for one seat and there were packages on our bus. We also arrived over 6 hours later than they said before we booked. Do not recommend this company - avoid at all costs. We also had to swap vans in Phnom Penh which was not communicated to us in any way. It was a 10 hour journey and we didn’t stop anywhere where we could buy any food or drink, on the 2 times we did actually stop. When exiting the vehicle, everyone was climbing and clambering over each other because the van was so packed.

The trip was 4 hours longer than said (13, not 9). We had to change the van and made a detour for that. The van was way too full with everyone’s backpacks on the floor.
