Your travel insurance could be invalidated if you travel against advice from the Foreign, Commonwealth & Development Office (FCDO).
Areas where FCDO advises against all but essential travel
FCDO advises against all but essential travel to parts of the south, near the Thailand-Malaysia border:
- Pattani Province
- Yala Province
- Narathiwat Province
- southern Songkhla Province – south of the A43 road between Hat Yai and Sakom, and south of the train line which runs between Hat Yai and Padang Besar
FCDO also advises against all but essential travel on the Hat Yai to Padang Besar train line that runs through these provinces.
This is due to regular attacks in the provinces by the border with Malaysia. See Safety and security .

This information is for people travelling on a full ‘British citizen’ passport from the UK. It is based on the UK government’s understanding of the current rules for the most common types of travel.
The authorities in Thailand set and enforce entry rules. If you’re not sure how these requirements apply to you, contact the Thai Embassy in the UK.
Passport validity requirements
To enter Thailand, your passport must have an ‘expiry date’ at least 6 months after the date you arrive and have at least 1 blank page.
Check with your travel provider that your passport and other travel documents meet requirements. Renew your passport if you need to.
You will be denied entry if you do not have a valid travel document or try to use a passport that has been reported lost or stolen.
Dual nationals
If you’re a dual national, it is best to leave Thailand on the same passport you used to enter – this will avoid problems at immigration.
Visa requirements
You can visit Thailand for a period of 60 days for the purpose of tourism, business engagements, and urgent or ad-hoc work. This visa category can be extended for another period not exceeding 30 days.
You can also apply in advance for a multiple-entry visa for up to 60 days.
For work, study or other reasons, you need a visa before you travel.
Overstaying your visa
If you overstay the period of your visa, you will get a fine of 500 Thai baht a day up to a maximum of 20,000 baht. You risk being:
- held in detention
- deported at your own expense
- banned from re-entering Thailand for up to 10 years
Conditions in detention centres can be harsh.
Vaccine requirements
To enter Thailand, you must have a certificate to prove you’ve had a yellow fever vaccination if you’re coming from a country listed as a transmission risk.
For full details about medical entry requirements and recommended vaccinations, see TravelHealthPro’s Thailand guide.
Customs rules
There are strict rules about goods you can take into or out of Thailand. You must declare anything that may be prohibited or subject to tax or duty.
Taking cigarettes into Thailand
It is illegal to take more than 200 cigarettes per person into Thailand. This is enforced at customs on arrival. If you go over the limit, you could be fined 10 times the value. Your cigarettes will likely be confiscated.
This guide also has safety advice for regions of Thailand.
Terrorism
There is a high threat of terrorist attack globally affecting UK interests and British nationals, including from groups and individuals who view the UK and British nationals as targets. Stay aware of your surroundings at all times.
UK Counter Terrorism Policing has information and advice on staying safe abroad and what to do in the event of a terrorist attack. Find out how to reduce your risk from terrorism while abroad.
Terrorism in Thailand
Terrorists are likely to try to carry out attacks in Thailand.
There are regular terrorist attacks in the 4 provinces in the southern tip of Thailand by the border with Malaysia. The Foreign, Commonwealth & Development Office (FCDO) advises against all but essential travel to these provinces.
Martial law is in place in most areas in these provinces, which means security forces have greater security enforcement and investigative powers. See Regional risks.
However, terrorist attacks could take place anywhere in Thailand. Attacks could be indiscriminate, including in places visited by foreign nationals. Stay aware of your surroundings, keep up to date with local media reports and follow the advice of local authorities.
Targets might include:
- security forces
- government offices
- hotels
- shops and supermarkets
- transport infrastructure
Political situation
The political situation can be unpredictable and has led to periods of civil and political unrest. Avoid protests, political gatherings, demonstrations and marches.
Crime
Protecting yourself and your belongings
To reduce your personal risk:
- carry your valuables and cash securely to guard against pickpocketing
- beware of bag-snatchers, especially on motorbikes
- take care when travelling in open transport like tuk-tuks
- avoid sleeping on buses and trains – people have had items taken from bags while asleep
Do not hand your passport over as a guarantee, for example to motorcycle or jet-ski rental businesses. Companies may hold on to passports against claimed damage.
Violent crime
Violent crime, including gun crime, rarely involves tourists. However, several foreign nationals were victims of gun violence in Bangkok in 2018. Take care when travelling in unfamiliar areas and avoid walking through isolated areas alone, especially at night.
Sexual assault
Violent sexual assaults and unprovoked attacks can happen in tourist areas across Thailand. Attacks are most common during full moon parties or similar events, and near bars late at night.
Drink spiking, alcohol and assaults
Drink spiking and drug-assisted sexual assault does happen in tourist areas around Thailand, with male and female victims. Do not leave your drinks unattended or accept drinks from strangers. Pre-arrange your transport home so you do not have to accept lifts in unlicensed vehicles.
Drinks served in bars are often stronger than those in the UK. Alcohol and drugs can make you less alert and more vulnerable to accidents, injuries, robbery and assaults.
Methanol poisoning
Alcoholic drinks containing methanol have killed people and caused serious illness. There is a risk of methanol poisoning from home brewed alcohol or counterfeit replicas of well-known alcohol brands. Affected drinks may include:
- local spirits, including rice wine
- spirit-based mixed drinks such as cocktails
- counterfeit brand-name spirits
To protect yourself from methanol poisoning you should:
- buy alcoholic drinks only from licensed liquor stores, bars, clubs, restaurants, and hotels
- avoid home-made alcoholic drinks
- check bottle seals are intact
- check labels for poor print quality or incorrect spelling
If the label, smell or taste seems wrong, do not drink the alcohol. These are signs it is illegal and could contain methanol. TravelHealthPro lists the symptoms of methanol poisoning.
Seek urgent medical attention if you or someone you are travelling with show signs of methanol poisoning.
Bank card fraud
Be aware of card fraud. Do not lose sight of your card during transactions. There have been incidents of ATM skimming. Use an ATM in a bank and always protect your PIN.
Job scams
Be wary of job offers that appear too good to be true. People have arrived in Thailand and been illegally transported to neighbouring countries on the promise of high-paying jobs, which turn out to be scams. When you re-enter Thailand you may then be detained while your immigration status is validated.
There have been incidents of:
- passports confiscated by scammers
- victims being held in poor living conditions
- coercion into undertaking wider online scamming activity
- pressure to make large payments to be released from sham jobs
Laws and cultural differences
The British Embassy in Bangkok’s video talks about what to be aware of when living or travelling in Thailand:
Criticising the Thai monarchy
Criticising the Thai monarchy (‘lèse-majesté’) is illegal. The law can be interpreted broadly and carries a long prison sentence. British and Thai journalists, human rights defenders and members of the public have faced charges for making political comments or sharing articles online that could be interpreted as being negative towards the institution of the Thai monarchy. The law also covers any accusations about members of the Thai Royal Family, past and present.
Posting images of people drinking alcohol or wearing clothing considered inappropriate can be illegal. Both the person who uploaded the images and the people in them could be fined or imprisoned.
Personal ID
Police may ask to check your passport. If you do not have it with you, you could be asked to produce it within 24 hours at a police station. Usually, a copy of the photo page of your passport will be sufficient.
Smoking and e-cigarette bans
It’s illegal to smoke in public with a fine of up to 5,000 Thai baht. E-cigarettes are illegal. You could be fined or imprisoned for carrying or using them.
Illegal drugs and prison sentences
Thailand has strict laws against drug use, possession and trafficking. Possessing small quantities of illegal substances can lead to heavy fines or imprisonment. Possessing Class A drugs can lead to the death penalty.
Conditions in prisons and other detention facilities in Thailand are harsh, with limited access to healthcare. Detainees have died in custody.
Some British nationals have suffered severe psychiatric problems because of drug use, sometimes leading to suicide.
Cannabis
Using cannabis in public places is illegal. Private recreational use of cannabis is legal if the Tetrahydrocannabinol (THC) content is below 0.2% by weight. There are still restrictions around growing and selling cannabis products. See more information on the Thai government’s website.
While low-strength cannabis is legal in Thailand, it is likely to be illegal in other countries you travel on to. This includes residual amounts, for example in bags or clothing or in your bloodstream.
It is illegal to take cannabis out of Thailand without the appropriate export permissions issued by the authorities. Illegally carrying cannabis, particularly large quantities, can lead to heavy fines or imprisonment in Thailand, the UK and other countries you may travel too.
LGBT+ travellers
Thailand is generally a safe place for LGBT+ travellers. However same-sex marriages are not recognised. Read more advice for LGBT+ travellers.
Wildlife, animal products and souvenirs
It’s illegal to buy, sell, kill or capture any protected wild animal or trade its parts without a licence.
Buying property in Thailand
Buying property in Thailand is not straightforward. Make sure you understand local laws and consult a lawyer before making financial commitments. British people have been victims of property scams.
Outdoor activities and adventure tourism
Elephant treks
Elephant treks can be dangerous, especially if elephants are mistreated or not handled properly. Use a reliable, licensed tour guide. British nationals have been seriously injured and killed because handlers have lost control of the elephant.
Swimming safety
Take care when swimming off coastal areas, especially during monsoon season. People have drowned in strong riptides. Thailand has lifeguards on duty at designated beaches and operates a flag system for safe swimming. Follow all warning signs, especially red flags.
See water safety on holiday from the Royal Life Saving Society.
Jellyfish can swim close to the shore, particularly during the rainy season from May to October. Jellyfish stings can be fatal. Take local advice from your hotel and dive centres.
Take care when swimming, diving, kayaking or white water rafting in rivers or close to waterfalls, particularly in the rainy season. Currents can be extremely strong.
See watersports safety advice from the Royal Society for the Prevention of Accidents (ROSPA).
Scuba diving
Diving schools may have limited resources and do not always observe safety and maintenance standards. Always:
- ask to see a dive operator’s credentials
- check the conditions on your insurance policy – some policies require dive instructors to have certain qualifications
- make sure safety equipment looks to be in good condition
- make sure oxygen is available on the boat
- ask about safety precautions, including the ability to transfer divers to a hyperbaric chamber
If you have not had any previous diving experience, check what to do if something goes wrong, including how to call for help while at sea.
Transport risks
Road travel
Thailand has a high number of road traffic accidents, particularly with motorcycles. The World Health Organisation (WHO) ranks Thailand as one of the world’s deadliest countries for fatalities on motorcycles.
If you are planning to drive in Thailand, see information on driving abroad. You’ll need to carry both the 1968 version of the international driving permit (IDP) and your UK driving licence while driving. You cannot buy an IDP outside the UK, so get one before you travel.
If you live in Thailand, you can apply for a Thai driving licence using your UK driving licence.
Car and motorcycle hire
Motorcycles and scooters for hire in beach resorts are often unregistered and cannot be used legally on a public road. Before you hire a vehicle, make sure your travel insurance covers you and check the small print of the lease agreement. Do not hand over your passport as a guarantee against returning a motorcycle or scooter.
By law, you must wear a helmet when riding a motorcycle.
If you drive a car or ride a motorcycle in Thailand without a valid licence, it could invalidate your travel insurance and you’ll be unable to claim if you have an accident or injury.
Sea travel
There are many passenger boat services operating between the mainland and islands. Boats can sink or collide, which has led to fatalities, including of British nationals. Accidents are usually due to:
- overloading
- poor maintenance
- rough seas, particularly during monsoon season
Extreme weather and natural disasters
Find out what you can do to prepare for and respond to extreme weather and natural hazards.
Rainy season
The rainy season is generally from May to October. In Koh Samui and the south-east of Thailand it is from November to March. However, the rainy season has been more unpredictable recently.
Heavy storms cause disruption including flooding and landslides. Lakes, caves and waterfalls are particularly at risk of dangerous flash flooding.
Follow the Thai Meteorological Department for weather warnings.
Earthquakes
Earthquakes and tremors are a risk in northern Thailand. Earthquake Track lists recent activity.
The US Federal Emergency Management Agency website has advice about what to do before, during and after an earthquake.
This section has safety advice for regions of Thailand. It only covers regions where FCDO has specific advice.
You should also read FCDO’s overall travel advice and safety and security advice.
Thailand-Malaysia border
FCDO advises against all but essential travel to parts of the south, near the Thailand-Malaysia border:
- Pattani Province
- Yala Province
- Narathiwat Province
- southern Songkhla Province – south of the A43 road between Hat Yai and Sakom, and south of the train line which runs between Hat Yai and Padang Besar
FCDO also advises against all but essential travel on the Hat Yai to Padang Besar train line that runs through these provinces.
This is due to regular attacks in the provinces by the border with Malaysia. See Safety and security .
Thailand-Cambodia border
Take extra care in border areas and follow the instructions of local authorities. The line of the international border near the Preah Vihear temple is disputed by Cambodia and Thailand. There are unexploded landmines in the border area. Stay on marked paths especially around Ta Krabey.
Stay alert to the local situation when travelling anywhere near to the border with Cambodia, and at land crossings between the 2 countries.
Thailand-Laos border
Not all land border crossings into Laos are open to foreign nationals. Even if the border crossing is open, you may need to get a visa for Laos in advance. Check the entry requirements in the Laos travel advice. Follow the instructions of local authorities and be vigilant in the border areas.
Thailand-Myanmar border
The security situation in Myanmar is unpredictable and liable to change without notice. See Myanmar travel advice.
Before you travel check that:
- your destination can provide the healthcare you may need
- you have appropriate travel insurance for local treatment or unexpected medical evacuation
This is particularly important if you have a health condition or are pregnant.
Emergency medical number
Dial 191 and ask for an ambulance.
Local number: 1669

See what health risks you’ll face in Thailand, including:
- Zika virus
- malaria and dengue
Altitude sickness is a risk in parts of Thailand. Read more about altitude sickness on TravelHealthPro.
Air quality
There can be high levels of air pollution in large cities. This includes Bangkok and Chiang Mai, which are also affected by seasonal regional smoke haze caused by farmers burning trees and crops. The high pollution and particulate count sometimes reach dangerous levels. This may worsen bronchial, sinus or asthma conditions.
Check air quality levels for many cities on the World Air Quality Index website.
Medication
The legal status and regulation of some medicines prescribed or bought in the UK can be different in other countries.
Hospitals and pharmacies across Thailand will usually accept UK prescriptions. Brand-name medication can often be more expensive than locally produced medication.
Medication sold on the street may not be genuine or may have been stolen. Taking medication without medical advice or a prescription can have serious health consequences.
Read best practice when travelling with medicines on TravelHealthPro.
Healthcare in Thailand
FCDO has a list of medical facilities in Thailand where some staff will speak English.
All hospitals require a guarantee of payment before treating patients. Make sure you have adequate health insurance.
Private hospitals in Thailand are of a high standard but can be expensive. Public hospitals and clinics do not always meet UK standards, particularly outside Bangkok.
Travel and mental health
Read FCDO guidance on travel and mental health. There is also mental health guidance on TravelHealthPro.
The Foreign, Commonwealth & Development Office (FCDO) cannot provide tailored advice for individual trips. Read this travel advice and carry out your own research before deciding whether to travel.
Emergency services in Thailand
Telephone: 191 (ambulance, fire, police)
Ambulance: 1669
Fire: 199
Police: 191
Contact your travel provider and your insurer if you are involved in a serious incident or emergency abroad. They will tell you if they can help and what you need to do.
