The short answer

Book longer journeys and tours in advance online with a fee-free card — domestic flights, sleeper trains, ferries and popular day trips. You'll usually get a better choice and price, and the payment goes through in baht at the card network rate.

Keep cash — around ฿2,000 to ฿3,000 in small notes — for metered taxis, tuk-tuks, songthaews, national park fees, tips and the many small tour operators, boat owners and dive shops that prefer it or add a fee for cards.

Use Grab or Bolt in cities, paying by card in the app, and tap a contactless card on Bangkok's MRT and the Airport Rail Link. Whenever a website or card machine offers to charge you in pounds, choose baht.

Domestic flights

Domestic flights are the quickest way to cover Thailand's long distances — Bangkok to Chiang Mai, Phuket, Krabi, Koh Samui, Udon Thani or Chiang Rai in an hour or so. Thai AirAsia, Thai Lion Air, Nok Air, Thai VietJet, Bangkok Airways and Thai Airways all fly domestically, mostly from Don Mueang (the low-cost carriers) and Suvarnabhumi.

Book on the airline's own website or app, or through a booking site, and pay by card. A few things to watch:

• Pay in baht. Airline sites often let you choose the currency. If you choose pounds, the airline converts at its own rate; choose baht and your fee-free card converts at the network rate.
• Check payment fees. Some low-cost airlines add a payment or processing fee depending on how you pay. Check the final total before you confirm, and compare payment methods if a fee appears.
• Add bags at booking. Low-cost fares often exclude checked luggage, and adding it at the airport costs much more.
• Use a credit card for larger bookings. Section 75 protection applies to purchases over £100 paid on a UK credit card — useful if an airline cancels or fails.

For connections, remember that Bangkok has two airports about an hour apart by road. Allow plenty of time if your international flight lands at Suvarnabhumi and your domestic flight leaves from Don Mueang.

Trains, including the sleeper to Chiang Mai

The State Railway of Thailand (SRT) runs long-distance trains from Bangkok's Krung Thep Aphiwat Central Terminal to Chiang Mai, the north-east, the south and the Malaysian border. The overnight sleeper to Chiang Mai is a classic journey in its own right.

• Fares are modest. Bangkok to Chiang Mai on the sleeper typically costs about ฿800 to ฿1,100 in a second-class air-conditioned berth and ฿1,900 to ฿2,400 in a first-class cabin, with lower berths costing a little more than upper ones.
• Book online through SRT's D-Ticket system about 30 days ahead — popular sleepers sell out at weekends and in the high season — and show the e-ticket on your phone.
• At the station, ticket counters can sell advance tickets; bring your passport. Cash in baht is the safest way to pay at the counter.
• Booking agents and travel websites sell train tickets too, adding a service fee — worth it if you can't get the SRT site to accept your card.

Short local and commuter trains are paid in cash at the station, often for just a few baht.

Buses, minivans and ferries

Buses and minivans

Government and private bus companies connect almost every town in Thailand, and minivans fill in the gaps — to Hua Hin, Pattaya, Kanchanaburi, Khao Yai and the ferry piers. At bus terminals you'll usually pay cash at the company's counter. Many routes can also be booked online by card, which is easier at busy times and saves a trip to the terminal.

Travel agents in tourist areas sell combined bus-and-boat tickets to the islands, often including hotel pick-up. They're convenient, usually paid in cash, and priced with a margin; compare the price with booking direct.

Ferries and speedboats

Ferries link the mainland to the islands — Koh Samui, Koh Phangan and Koh Tao in the Gulf, Phuket, Phi Phi, Krabi and Koh Lanta in the Andaman Sea. Lomprayah, Seatran and others sell tickets online, by card and other methods; on 12 October 2026 Lomprayah sailings from Koh Samui to Koh Tao were listed from ฿700, taking 1½ to 2¾ hours depending on the boat.

• Book ahead in high season and around holidays, when popular sailings fill up.
• Keep cash for the pier — some piers charge a small pier or environmental fee, and longtail boats and local ferries are cash only.
• Check what's included in a joint ticket — the bus or minivan to the pier, and the transfer at the other end.
• Weather matters. Rough seas can cancel sailings; check the refund policy before you pay.

Booking online in advance usually means paying by card in baht, a confirmed seat and a clear record if a sailing is cancelled.

Getting around Bangkok and other cities

• BTS Skytrain: fares are ฿17 to ฿65 on the Sukhumvit and Silom lines. The BTS doesn't accept contactless bank cards yet — use cash or QR at the machines, a single-journey ticket, or a rechargeable Rabbit card. Contactless payment is expected as part of a unified ticketing rollout targeted for 2027.
• MRT (Blue, Purple, Yellow and Pink lines) and the Airport Rail Link: tap in and out with a contactless Visa or Mastercard. On a fee-free card there's nothing extra to pay.
• Grab and Bolt: add a UK card in the app and pay automatically — no cash, no haggling, and a fixed price before you book. The easiest way to get around Bangkok, Chiang Mai, Phuket and Pattaya.
• Metered taxis: cash. Ask for the meter ("meter, please") and have small notes.
• Tuk-tuks and motorbike taxis: cash, price agreed before you set off.
• Songthaews (shared pick-up trucks): cash, usually a small fixed fare per person on set routes, more for a private hire.

Tours, day trips and activities

Elephant sanctuaries, island-hopping, cooking classes, zip lines, white-water rafting, temple tours, kayaking, off-roading — Thailand has endless things to do, and there are two main ways to pay for them.

Booking online in advance

Booking through an online platform means paying by card, seeing reviews and the cancellation policy before you pay, and having a confirmation in your inbox. For popular trips in the high season — the Similan Islands, Phi Phi, the best elephant sanctuaries — booking ahead may be the only way to get a place. Pay in baht if you're given the choice, and use a credit card for larger bookings.

Booking locally

Tour desks, hotel receptions and travel agents sell the same trips on the ground, usually for cash, sometimes with a card surcharge. Prices can be negotiable, especially out of season, but you get less information about the operator and fewer rights if the trip is cancelled. Ask exactly what's included — transfers, lunch, equipment, park fees — and get a written receipt.

• Deposits: some operators take a deposit when you book and the balance on the day. Keep the receipt.
• Cancellations: weather often cancels boat trips. Check whether you'll get a refund or a new date before you pay.
• Extras on the day: park fees, equipment hire and tips are often paid in cash on the day, even if the tour itself is prepaid.
• Insurance: check your travel insurance covers the activity — many policies exclude some adventure sports.

Diving and dive courses

Thailand is one of the world's most popular places to learn to dive, and Koh Tao in particular is famous for good-value courses. In 2026, an Open Water course on Koh Tao typically costs around ฿11,000 to ฿12,500 — roughly £250 to £280 — including certification and equipment, with fun dives for certified divers around ฿800 to ฿1,200 each.

Many dive shops prefer cash, and some add a fee for card payments. On a ฿12,000 course, a 3% card surcharge is ฿360 — more than the ฿220 fee for withdrawing the cash from an ATM on a fee-free card. Ask about card fees before you sign up, and get a receipt for any deposit.

• Marine park fees are often charged on top of dive trips in national marine parks, usually in cash.
• Liveaboards to the Similan and Surin islands are usually booked and paid in advance, often with a deposit.
• Insurance matters most here. Many travel policies limit diving to a maximum depth or exclude it unless you add cover. Check yours, or get specialist dive cover, before you go.

Golf

Golf in Thailand is excellent value by British standards, and Hua Hin, Pattaya, Chiang Mai, Phuket and the Bangkok area all have dozens of courses. Expect three separate payments:

• Green fee — from around ฿1,500 at local courses to more than ฿6,000 at championship venues, usually payable by card at the clubhouse or in advance.
• Caddie fee — around ฿350 to ฿500, paid to the club. Caddies are compulsory at almost every course.
• Caddie tip — around ฿400 to ฿500 in cash, given directly to your caddie after the round.

Buggies (carts) are included at some high-end courses and cost around ฿600 to ฿800 at others. Pay the club in baht by card where you can, and carry enough cash for tips and drinks on the course. Golf packages that bundle green fees, transfers and hotels are often cheaper than booking each round yourself, particularly for groups.

Fishing

Fishing is another big draw — deep-sea and game-fishing charters from Phuket, Pattaya, Krabi and the Gulf islands, and freshwater fishing parks and lakes around Bangkok and in the north. Charter boats usually take a deposit when you book and the balance on the day, often in cash; day tickets at fishing parks and lakes are normally cash too. As with diving, check whether your travel insurance covers time on a boat, and agree in writing what the price includes — tackle, bait, fuel, food and transfers.

National parks, temples and dual pricing

Thailand charges foreign visitors more than Thai citizens at national parks and many attractions — a system known as dual pricing. National park entry fees for foreign adults are set in four bands:

• Category 1 parks: ฿100 (children ฿50).
• Category 2 parks: ฿200 (children ฿100).
• Category 3 parks, including popular ones such as Erawan: ฿300 (children ฿150).
• Similan and Surin islands: ฿500 (children ฿250).

Vehicle fees are extra — for example ฿20 for a motorbike and ฿30 for a car at Erawan. Bring cash: park offices often don't take foreign cards, and digital payment options are mostly designed for Thai bank apps. Temples, museums and attractions vary; major sights increasingly take cards, but small temples and local attractions are usually cash only.

If you've booked a tour, check whether park fees are included — they often aren't.

Tips for guides, drivers and crews

Tipping isn't compulsory in Thailand, but it's appreciated, especially by guides, drivers and boat crews whose wages are low. A small cash tip — ฿100 to ฿300 for a day guide or driver, a little more for a private tour or a good boat crew, and around ฿400 to ฿500 for a golf caddie — is common. Tips are almost always given in cash, so keep some small notes aside.

Living in Thailand: paying like a local

Once you live in Thailand and have a Thai bank account, paying for transport and activities gets much easier. Thai banking apps pay any Thai QR code in seconds — at market stalls, piers, park offices and small operators that never took foreign cards — and you can top up transport cards and pay for tickets from your phone.

Some attractions offer residents the Thai price if you can show a Thai driving licence or work permit, so it's worth asking. And regular domestic travel adds up: a good fee-free card for bookings, a Thai account for day-to-day spending and a sensible way of moving money from the UK all make a difference over a year.

If you're planning a move, the bigger questions are how to set up your money, pension and insurance for life here — that's where our team can help.
