King Bhumibol Adulyadej on Thai bank notesThe main form of currency in Thailand is the Thai Baht (THB).

There are many banks in Koh Samui. Most open from 8:30am until 5:00pm Monday to Saturday, with some opening on a Sunday.

ATMs (cash machines)
ATMs ThailandATMs are everywhere in Koh Samui and work in exactly the same way as they do in your home country but will charge you to withdraw money from your bank account in your native country. There are options to chose English and other languages.

The maximum allowable withdrawal at once is of 20,000 baht. The maximum you can withdraw in 1 day depends on the limit on your card not the ATM.

ATMs in Thailand give you your cash first and then your card unlike in some European countries. Remember to take your card at the end!

Currency exchange offices
Currency exchange offices are open 7 days a week and often till 10 pm.  All the common foreign currencies are accepted in banks everywhere, in cash or in travelers checks.

Like in other holiday destinations, different bank do offer different exchange rates so do some comparisons before exchanging.  Typically you will get a better rate exchanging your money in Thailand than you will changing your money in your home country.

Credit cards
The most widespread cards are Visa, Mastercard and American Express. These cards allow you to withdraw money from any ATM which displays the same logo/symbol as your card, provided you have PIN code, otherwise you also could withdraw money from bank counters (4% commission or more!) or pay with your credit card in miscellaneous shops, hotels and restaurants.

Money transfer
If you urgently need to send or receive money in Koh Samui, Western Union provides a safe, reliable and fast money transfer worldwide.

Travelling to Koh Samui

Thailand has very good infrastructure and is extremely well organized to travel to Koh Samui.

Travel to Koh Samui by air

To travel to Koh Samui by air is the most expensive way to get to Koh Samui but it is the most convenient and certainly the fastest.

Bangkok Airways, Thai Airways and Firefly operate to Koh Samui International Airport from a number of locations including Bangkok, Phuket, Pattaya, Hong Kong and Kuala Lumpur. Koh Samui International Airport is actually privately owned by Bangkok Airways, as such they have a bit of a monopoly on the airport explaining why the cost of travel is so expensive compared to similar journeys elsewhere in Thailand.

If you want to travel to Koh Samui quickly by air but for around half the price, you can fly to Surat Thani Airport and catch a minibus (about 1 hour) to Donsak’s ferry port for a boat to Koh Samui (about 90 minutes).

Be aware that the last ferries leave at 7pm so allow yourself plenty of time to get there, otherwise you'll have to spend the night in Surat Thani.

Travel to Koh Samui by rail

Surat Thani train stationTraveling by train to Koh Samui can be a lot of fun and is great for meeting new people and making friends with other travelers. The train service is impeccable and timetables are generally respected, although it is true trains are not the fastest way to travel (e.g. 600 km over 12 hours) in Thailand. To make the journey bearable there are air conditioned carriages, VIP coaches and sleeper coaches which have beds with fresh sheets for you to relax. There are berths at the top bottom. We advise you to book the bottom bunk (a little more expensive) because it is more spacious and airier, especially if you happen to be over 6ft (183cm).

Food and snacks are available but it is generally a rather poor selection of junk food (cakes, chocolate, noodles, pork buns, soft drinks) and on the expensive side. We suggest you to stock up with food at the stations as there is always a market or food vendors nearby. When you stop at stations, there are almost always people who sell delicious cheap food either on the train or by the window.

All coaches are no smoking.

Book your ticket at least 3 days in advance to guarantee your travel date. Air-conditioned car-sleepers are very cold so either ensure you have something to keep you warm or book 2nd class fan.

Travel to Koh Samui by road

There are bus services to most destinations in Thailand. Bangkok to Koh Samui buses leave from the Southern Bus Terminal. There are VIP, first and second-class buses available. These are all air conditioned. For easier & cheaper travel, you can buy a bus/ferry combination ticket.

It stops almost every time a person holds out the hand by the roadside, no air-conditioning, wide opened windows but you could have very pleasant encounters in it with the local people and you travel really for an absurdly low fare.

Coach (economy)
A well maintained air conditioned bus. A reasonable amount of space between seats and the seats do recline comfortably. Always travels overnight (see below for details).

Coach (VIP)
Seatran Coach to BangkokA nice air conditioned bus with on board toilet. This has fewer seats on board than the economy bus and they also recline a lot further. As a VIP you will receive a few extra snacks included in the cost of your ticket. Coaches always travel to Koh Samui overnight. You leave Bangkok between 5.30pm and 8pm and journey takes around 10-12 hours to Donsak, about 700 kilometers from Bangkok. Once in Donsak, you will travel by car ferry to Koh Samui, which takes about 1 hour and 45 minutes. Then you will be transferred to the bus depot nearby in Nathon, where there will be a taxi rank for you to get to where you need to go on Koh Samui.

On all the coaches, they put on a movie (in Thai language or sometimes in English) or the Thai TV during 2 hours after your departure. All coaches will stop one or several times on the journey at local truck stop restaurants with bathroom facilities. VIP buses mainly have their own bathrooms.

They will take you where you need to go but will stop to pick up other passengers and some times go a longer route to get more customers.

Songtaews operate from early morning to 10pm. Prices starts at around 30-60 Baht per person, but it’s more expensive at night after 6pm. After this time you will have to negotiate the price but typically it will be around 70-100 Baht per person.

Koh Samui is full of officially licensed taxis, which are comfortable, air conditioned and circulate the island. Even though many of them display “Meter” they rarely use it and the fare should be negotiated before getting in the taxi.
