Bangkok to Koh Samui Destination Reviews

The first ten hours of the bus journey were unfortunately not very pleasant. The seats were squeaky, the bus made a beeping sound every two to five minutes, and overall it was not very comfortable. During the scheduled breaks, the stops were not at official gas stations or regular convenience stores, but at shops operated by the company itself. This created the impression that passengers were being subtly encouraged to purchase food or snacks there, which felt somewhat uncomfortable. The remainder of the trip was good and seamless. Both the ferry transfer and the second bus were perfectly fine and much more comfortable.

The bus was late and also not in good condition, it looked like it was from the 1960s, most of the USB ports were broken, some seats could not be reclined, very little leg room. The staff was far from polite and professional. When we arrived at the place where we need to transfer to another bus the staff simply started screaming in the middle of the night and scared the living shit out of everyone on the bus that was asleep or half asleep. They were screaming everyone heading to Phuket get off here, when what they actually meant was Everyone needs to get off the bus so there was a lot if confusion due to bad communication on their end. The screaming staff was the worst I have ever encountered, and can just say if you travel with them don’t expect anything even close to the word of customer service

This honestly wasn't a bad trip like others have claimed, I think some people just have too high of a standard, especially for SE Asia. In saying that, don't pay for VIP, all tickets are the same. No seat allocations so you need to ensure you get on the bus earlier to get a seat you want. Water and snacks were provided. We travelled from Bangkok to Koh Samui and had no issues. You do a transfer to shuttle buses at Surat Thani that takes you to your respective destination or ferry terminal. PSA it's also cheaper to buy tickets online than at the shop, they can't price match 12go

All went good as far as the transportation is concerned. We arrived 1h30 late but that's alright given the length of the trip. HOWEVER, in the night bus I saw a guy (who I suppose was one of the drivers or a member of the staff) crawling in the aisle in the middle of the night (the bus lights were off), and trying to steal from people's bags... Thankfully, nothing was stolen as I reacted when I saw him, but that is not acceptable... WATCH OUT!

Very easy, everyone along the way was helpful. Seats recline enough to get some sleep. They provide a pillow, blanket and some snacks, the bus stops at services to allow people to go to the toilet and get a quick bit of food. The boat is also just as easy. Taxi’s and Tuk Tuk’s are waiting the other side for a lift to your hotel.

Good ride. Only thing to look out for is to go to the right location, which is not directly at Khao San Road, but 7 minutes walking away. Airco, food and a blanket were included!

Note that the travel time is for your reference only and can depend on different factors such as traffic and weather conditions. Heavy rainfalls almost inevitably make the trip longer due to poor visibility or floods. Road and surface repairs which happen quite often, result in detours and longer travel times. Major national holidays, long weekends, or peak season periods may cause delays both in departures and arrivals – plan accordingly to avoid disappointment, especially if you have further connections and a tight schedule.

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.
