Phnom Penh to Sihanoukville Destination Reviews
EW
Eva WI had booked a bus ride from Phnom Penh to Siganoukville but when we turned up at the indicated boarding station it turned out that the travel agency didn’t exist anymore. 12Go made no attempts to help us nor have the refunded the fee yet, one week after the event. We had to book another bus ride to reach our ferry in Sihanoukville. Even worse, 12Go is ignoring my Emails and not getting back to any of my attempts to get in contact.
Very unpleasant und unprofessional behaviour!

We forgot our laptop bag on the bus and when we realized it the bus had left the terminal, they still managed to bring out bag back 2 hours later. Very trustworthy and bus staff was very respectful and extremely nice. I will definitely travel with you again. Sina.

Jacub SThe coach was on time from Phnom Penh and set off promptly. We were all given a free water and pastry! We had one stop off at a services about 2 hours into the journey for a snack and toilet stop. No complaints other but rather to point out that it arrived 15/20ish minutes behind schedule so don’t book a boat for 11am if it says 10:45 arrival (hope this helps someone!)
Overall comfortable, air conditioned and tinted windows. Easy journey, thank you!

Helen TThe ride itself was great but we arrived late and we only had a 15 minute window for the speedboat. Someone from the bus company must have contacted the Speedboat because they waited for us. It was a stressful run. I'm also not sure why my credit card was charged $6 more than what's on my receipt.

Timo MThe seats in the limousine bus were were small and everything crammed. Luggage was stored in the isles. We had a 1 h delay on aa 3 h ride because the driver was going slowly and there were several unplanned stops to let single local people out (sometimes at 5 min intervals which seemed even more unnecessary).

Travelling by bus essentials
- If you are planning to travel during the high season, weekends, or national holidays, booking your bus tickets in advance is highly recommended. The demand is at its highest, yet very often, the number of coaches serving the route remains the same. The earlier you reserve your seat, the better. On some routes, you need to secure your ticket more than a month in advance; on others, a couple-of-days advanced booking is enough. During such periods, try to book online beforehand whenever possible, as showing up at the bus station without a ticket may result in many-hours of waiting in the queue or leave you downright stranded.
- VIP, 1st, Gold, and similar bus tickets are the most expensive option, but they provide a higher level of comfort. Normally the price of such tickets will include wide soft reclining seats, blankets, water and snacks or lunch, and sometimes some toiletries. Upper-class buses travel faster, make fewer stops during the route, and normally provide more spacious seating to their passengers and a better travel experience.
- Not all buses have an on-board toilet, but generally, for all trips longer than three hours, all operators schedule a bathroom and/or a lunch stop. While operators definitely do their best to keep on-board toilets clean, the smell may be an issue sometimes. For longer trips, booking a seat a bit farther from the toilet may be a good idea. Also, using bathroom stops for your toilet needs is always better than trying to find your balance in an on-board toilet on the run.
- If you travel by an air-con bus, make sure to pack layers. A hoodie, a warm scarf, or a beanie hat may prove a good idea. Air-conditioning on buses tends to be excessive, and running nose and sore throats abound after even not the longest bus rides.
- Always use the security belts even if your bus ride attendant or driver does not insist on it. Your safety comes first – for you, for sure. All buses normally are equipped with security belts, but they may be fixed behind your seat. Take time to find the belt and fix it appropriately.
- To avoid being disturbed by overhead lights, switched on during stops even at night, and too loud music or sound from the on-board entertainment system, have earplugs and a sleeping mask at hand.
- As a courtesy to other passengers, avoid using strong perfumes or smelly foods. Some foods like cheeses or durians are forbidden to take on-board – check in advance. Alcohol is also prohibited on the majority of buses.
- Note that if the bus requires refuelling en-route, passengers will be asked to get off the bus. Operators are not allowed to refuel with passengers on board due to safety reasons. Usually, it takes from 5 to 10 minutes and is often combined with a toilet/lunch stop.
- If not stated otherwise in your tickets, arrive at the bus station 20-30 minutes before departure. It will give you enough time to find the departure platform and check-in. For international trips, you may need more time for check-in and border formalities.
