Koh Rong to Siem Reap Destination Reviews

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.

They advertised with 9 hours, it was 13…. First we went with the boat, that was fine. We came to the officie but nobody was there evertything closed. Without further information… luckly at 08:00 AM a driver came at took us to the head station. From there we went to phnom penh. With trafic, and a transfer to another bus (20 min waiting). Then to the next officie. Driver said nothing got out, then we wait for 20 minutes, nothing. So i got out, asked the driver, he said another 10 min waiting for people. Those 10 minutes were again 20+ minutes. After being 1,5 hours in phnom penh with all the waiting we went to siem reap. From 06:30 til 19:30, a bummer when they said the arrival time would be 15:30… but the bring you from A to B. Longer than expected and with mosquitos and cockroches in the car…

We were late almost 4 hours, instead of getting at 19:55, like the app listed, we arrived after 23:30, while we were at phnom penh, waiting for the van to siem reap, the staff ignored us when we questioned them on when it will arrive, and eventually they took me on a scooter, with no helmet and while i carry all my luggage to a different company to take me to siem reap. Aweful time management, aweful service, dangerous at some parts and not suggested to anyone
