I had a great experience traveling from Siem Reap to Phnom Penh with Cambolink21 Express. The best part of the journey was the punctuality. The bus departed right on schedule without any unnecessary delays, which made planning my day very easy. ​The driver drove safely and responsibly the entire time, keeping a steady pace while still managing time well. Rest stops were well-timed and quick, so we did not waste any minutes on the road. We arrived at the Phnom Penh station right on time as promised. ​It was a very reliable, stress-free, and punctual service.

We arrived at the supposed pick up location prior to the departure time. We were told the 8.30am bus was not running, so they put us on the 9.30am one. They then put us on a tuktuk and drove us back into town to the Capitol bus office, where we sat waiting for a while. Then a mini van came and drove us to another location where the coach was. We didn’t feel very safe as there was no communication telling us where we were going or what was happening. The bus itself was good, it had ac, foot rests and reclining seats. The bus stopped every 2 hours for a toilet break - bear in mind these toilets are Asian style squat ones with no toilet paper or flushes. What was slightly annoying was the driver stopped at random points to drop off parcels and pick up/drop off locals at unofficial stops (the bus was meant to be direct). We arrived at around 4pm, so it was 6h30min ride. The transport service was provided by Capitol buses not Mey Hong.

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.
