Most travelers from Malaysia reach Hat Yai through one of two border crossings in Songkhla province: Sadao, opposite Bukit Kayu Hitam, for buses, vans and cars, or Padang Besar, where the train and a smaller road crossing meet. Both are about an hour from Hat Yai. Since Saturday 11 July 2026 the Sadao crossing uses a new, larger checkpoint, open daily from 05:00 to 23:00 Thai time (06:00 to midnight Malaysian time).
This page is written for readers starting in Malaysia or Singapore: what you need before the border, how each route works, and what changes when you bring your own car. For Hat Yai itself, its markets, food and the trip to Songkhla, see our Hat Yai guide.

Before you leave: visa, TDAC and the 30-day rule
Citizens of Malaysia and Singapore can enter Thailand without a visa for tourism and stay up to 30 days (as of October 2026). This changed on 15 September 2026, when Thailand ended the 60-day exemption that applied from July 2024, so older posts in travel groups are out of date. Most other visa-exempt nationalities can use the exemption at land borders only twice per calendar year, but the Tourism Authority of Thailand says nationals of Malaysia, Brunei, Indonesia and Singapore are exempt from that limit. Our older page on visas and retirement in Thailand covers long-stay options; for the short-stay rules by nationality see the visa exemption guide.
Every foreign visitor, including children, must also file the Thailand Digital Arrival Card (TDAC) for each entry, by land as well as by air. It is free on the official site, tdac.immigration.go.th, and can be submitted up to three days before arrival, including the day itself. Sites that charge a fee are not official. Our guide to filling in the TDAC walks through each field, including the land-border choices.
Leave your vape at home before you reach Sadao. E-cigarettes and vapes are banned in Thailand, and customs fines are strict. Cigarettes are limited to 200 per person and alcohol to one liter; see the page on Thai customs allowances.
Immigration can ask for proof of funds (10,000 baht per person or 20,000 baht per family for visa-exempt visitors) and onward travel. It is rarely asked of Malaysians on a weekend trip, but carry a card and some cash. Your passport should be valid for at least six months.
By train via Padang Besar
Malaysia's KTMB runs its electric ETS trains on the West Coast Line up to Padang Besar, with direct services from KL Sentral and from Gemas. At Padang Besar you go through Malaysian exit and Thai entry formalities, then continue to Hat Yai Junction on a State Railway of Thailand (SRT) shuttle train. There are only a few shuttles a day, so check the current timetable with SRT or at the station rather than relying on an old blog post, and allow for the one-hour time difference when reading times.
The train is comfortable and avoids road queues, and it is the obvious choice from Kuala Lumpur, Ipoh or Butterworth. There is one important caveat for some readers. The UK Foreign, Commonwealth and Development Office (FCDO) advises against all but essential travel "on the Hat Yai to Padang Besar train line", and going against FCDO advice can invalidate UK travel insurance. The US advice does not mention this line. If you are British, or your insurer follows FCDO advice, take the road through Sadao instead.
From Hat Yai Junction, SRT trains continue north to Bangkok; long-distance services now arrive at Krung Thep Aphiwat Central Terminal. Our guide to Thailand's night trains explains the sleeper classes.
By bus or van through Sadao
Buses and vans to Hat Yai leave from Kuala Lumpur, Penang and other northern Malaysian towns, and coaches run from Singapore. Nearly all use the Bukit Kayu Hitam–Sadao crossing. Everyone leaves the vehicle at each immigration post, walks through with their luggage or as the operator directs, and boards again on the other side. Expect the border to take longer on Friday evenings, Sunday afternoons and during Malaysian school holidays.
The new Sadao checkpoint opened on Saturday 11 July 2026, after the Thai and Malaysian prime ministers launched it the day before. It lies about 6 km east of the old Dan Nok post, which closed permanently, and has far more vehicle and immigration lanes. Maps and directions written before mid-2026 may still show the old route.
Book with an established operator, ask where the bus stops in Hat Yai, and keep your passport and TDAC confirmation within reach. Vans are faster but cramped and carry little luggage; our guide to minivans in Thailand explains the trade-offs.
Driving your own Malaysian or Singaporean car
Driving to Hat Yai is popular with Malaysian families, and the rules are simpler for you than for most foreign drivers. Thailand's Department of Land Transport requires most foreign-registered private vehicles to obtain a Foreign Vehicle Permit through a licensed Thai travel agency, with a Thai escort vehicle. Its own manual states that "vehicles registered in Lao, Malaysia and Singapore" are exempted from that regulation. You do not need an agency or an escort.
You still need paperwork at the border. Bring:
- your passport and TDAC confirmation;
- the original vehicle registration document (geran or the Singapore log card), and a letter of authorization from the owner if the car is not in your name;
- your driving licence, plus an International Driving Permit to be safe; our article on international driving permits in Thailand explains when it is required;
- Thai motor insurance for the car, because a Malaysian or Singaporean policy normally does not cover driving in Thailand.
At the vehicle counter, Thai Customs registers the car as a temporary import and gives you a document that stays with the car until you drive it out again. Keep it safe, because you hand it back at the exit. Thai insurance is sold by agents on both sides of the border; buy it before you reach the checkpoint so you are not held up.
Print TM.2 and TM.3 at home if you are driving. Malaysian and Thai driving guides report that Thai immigration asks drivers for form TM.2 (information on the vehicle) and TM.3 (passenger list) at the car lanes. We could not confirm on an Immigration Bureau page that every private car needs them, but carrying completed copies costs nothing and can save a queue.
Once in Thailand you drive on the left, as at home, but traffic habits differ. Thai rental cars cannot be taken into Malaysia, so if you are flying in and want to drive back, plan two separate rentals; the guide to renting a car in Thailand covers this. For the full detail on temporary-import papers and insurance for foreign-plated cars, our sister site has a guide to bringing a foreign-plated vehicle into Thailand.
Choosing a route
| Route | Crossing | Good for | Watch out for |
|---|---|---|---|
| ETS + SRT shuttle | Padang Besar | KL, Ipoh, Butterworth; no road queues | Few shuttles a day; UK FCDO advice covers this line |
| Bus or coach | Sadao | Singapore, KL, Penang; one ticket to Hat Yai | Weekend queues; check drop-off point |
| Van | Sadao | Penang and northern Malaysia; speed | Cramped, little luggage space |
| Own car | Sadao or Padang Besar | Families, flexibility, shopping | Customs papers, Thai insurance, 05:00–23:00 Thai time at Sadao |
Arriving in Hat Yai and getting around
From either crossing it is roughly an hour by road to central Hat Yai; our routing measurement gives about 59 km from Padang Besar. Buses and vans usually stop near the city center. Change some money or withdraw baht soon after you arrive: KBank and SCB ATMs charge foreign cards 250 baht per withdrawal, or 350 baht with Mastercard (October 2026), so fewer, larger withdrawals are cheaper, and our guide to exchanging money in Thailand compares the options.
A local SIM or eSIM makes Grab and maps easier; see SIM cards and eSIMs in Thailand. Remember to leave before your 30 days are up: overstaying costs 500 baht a day, up to 20,000 baht, and can lead to a ban; our page on overstaying in Thailand explains the rules. For the other crossings along the border, including the routes to Satun and the islands, see the overview of overland routes from Malaysia.
Frequently asked questions
What time does the Sadao border open?
The new Sadao checkpoint, in use since 11 July 2026, operates daily from 05:00 to 23:00 Thai time, which is 06:00 to midnight Malaysian time. Thailand is one hour behind Malaysia and Singapore, so plan your arrival on the Malaysian side with that in mind.
Do Malaysians need a visa for Hat Yai?
No. As of October 2026 Malaysian citizens can stay up to 30 days visa-free for tourism, and they are exempt from the limit of two land-border entries per year. Every visitor must still complete the free TDAC online before arrival.
Can I drive my Malaysian car to Hat Yai?
Yes. Cars registered in Malaysia and Singapore are exempt from Thailand's Foreign Vehicle Permit, so you do not need a Thai agency or escort. Bring the original registration document, your licence, Thai motor insurance and your passport, and keep the customs document for the car until you leave.
Is the train from Padang Besar to Hat Yai safe?
The US government does not mention the line. The UK FCDO advises against all but essential travel on the Hat Yai to Padang Besar train line, which can affect UK travel insurance. British travelers and anyone whose insurer follows FCDO advice should use the road through Sadao.
