This island in the Gulf of Thailand is renowned for its idyllic beaches and for its mountainous rainforest interior. With its luxurious spas it attracts visitors from around the world but also has a vibrant nightlife scene and cheap places to stay that draw the backpacking crowd. If you’re wondering how to travel from Bangkok to Koh Samui, read on for our guide.

Flights from Bangkok to Koh Samui

Koh Samui is over 700 kilometers from Bangkok, so easily the quickest way to get here is by airplane, but flights from Bangkok to Koh Samui can be expensive meaning that flying will not be for everyone. Putting the cost aside for a moment, Koh Samui does have its own airport, situated in the north east of the island, which was originally built by Bangkok Airways as a private airport solely for their use, giving this airline a monopoly on direct flights between the two destinations. If you want to fly direct, Bangkok Airways is the only airline available but the good news is they have frequent flights, departing almost hourly.

With so many daily flights offered by Bangkok Airways it’s usually pretty easy to find a seat on a plane, though this won’t always be the case around Thai holiday periods. Airfares can vary substantially depending on when you book your ticket; it’s always advisable to book as far in advance as you can for the best deals as you’re likely to have to pay as much as double if you try to buy a ticket on the day of departure. Either way, flights with Bangkok Airways are considered to be expensive by Thai standards.

There are a couple of other options for flights between Bangkok and Koh Samui. You could actually fly to Surat Thani Airport or Chumphon Airport. Both are on the mainland and so both of these options will also require you to take a ferry across to the island. Ferry connections are good though, and with low cost air carriers providing flights to both airports, you could save yourself a significant amount of money traveling this way.

Once you arrive at Koh Samui Airport (if you’re catching a direct flight from Bangkok to Koh Samui) there’s plenty of ground transportation to get you on your way to a hotel or resort. Minibuses and private minibuses are a good option, but there are not usually many taxis available at the airport.

An even cheaper option than the low cast airlines is to take the train and ferry from Bangkok to Koh Samui. The biggest disadvantage to traveling by train and ferry is the time that it takes, though you could argue that if you travel on a sleeper train overnight, you’re not actually losing much time out of your vacation. From Bangkok’s new Krung Thep Aphiwat Train Terminal you can catch a train in the evening, travel overnight, then wake up the next morning as you arrive at Surat Thani station. At Surat Thani you’ll get off the train and board a special shuttle bus which will take you to the coast and the Donsak Pier.

Once you’ve arrived at Donsak Pier your trip from Bangkok to Koh Samui becomes even more interesting and exciting! You have the option to take a conventional ferry if you want to sit back and enjoy the journey. It takes around 90 minutes by conventional ferry, or you can take the faster option and travel by high-speed catamaran. This takes just 45 minutes to get to Koh Samui so if you’re eager to hit the beaches and the bars this would be the best option. You could also look at ferries from Ban Don Pier which are operated by Seatran Ferries whereas those from Donsak Pier are operated by Raja Ferry.

Combined train and boat tickets can be bought from Krung Thep Aphiwat Train Terminal in Bangkok so you don’t have to buy separate tickets for each leg of the journey, or you can buy in advance online. However you choose to buy your tickets you really should buy them before your day of travel as these trains do get fully booked.

Bus and Ferry from Bangkok to Koh Samui

One final option for traveling from Bangkok to Koh Samui involves a bus and ferry ride. With this option you’ll take a bus from Bangkok to Chumphon (stopping for a little in Hua Hin). At Chumphon you then get on the high speed catamaran which travels via the islands of Ko Nang Yuan, Ko Tao and Ko Pha Ngan. Going this route is scenic as you’ll get to see more islands along the way but it does take time – the entire journey is around 11 hours of which half of this will be on the boat.

So there are three different options for travel from Bangkok to Koh Samui. Which one you choose is going to depend firstly on your budget, then on how quickly you’d like to get to the island. Flights are great, but they are expensive if you’re traveling on a budget, but we’ll leave that decision up to you.

How do you get from Bangkok to Koh Samui?
