Sophie S2 stars because the boat was on time and good, and the first bus was good.
We went from Koh Rong to siem reap. The boat from KR to sihanoukville was fine and good. The bus from sihanoukville to Phnom Penh was fine, cramped but fine and air coned. The second bus however, was the worst journey I’ve had in my whole SE Asia trip. It was completely unacceptable

Sarah RAll in all it was okay, it was pretty comfortable and I almost slept the whole ride, only the bus stopped very often and we arrived an hour late and it didn’t bring us to the location that we were supposed to get dropped off, it was further outside the city so we had to get a Tuktuk to our hostel.

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.
