What to watch out for in Thailand? 11 most common scams you need to know about before you go
February 23, 2026
Travelling to the Land of Smiles is a dream, but a lack of knowledge about local realities can cause stress. Are you wondering if Thailand is safe? Generally speaking, yes, but specific tourist traps in Thailand, different traffic laws and health risks require attention. The following guide discusses safety in Thailand in detail and what to watch out for in 2024, so you can focus on discovering the beauty of Asia.
How to prepare for your trip to avoid logistical problems in Thailand?
Good logistical preparation is the basis for safe travel. Problems often arise from incorrect assumptions about documents, climate or finances. Check the validity of your passport (minimum 6 months) and take care of the following issues, knowing what not to do in Thailand before you leave the UK.
What travel insurance best covers medical expenses in Thailand?
The policy must cover a minimum of EUR 50,000 – 100,000 due to the very high prices in private Thai hospitals. Standard insurance for Thailand included with a credit card is often insufficient. The policy should include an extension for extreme sports (e.g. scooter rental, diving) and an alcohol clause.
A wide range of assistance is also key. The cost of medical transport to Poland can run into hundreds of thousands of zlotys. Good travel insurance is therefore absolutely essential. Keep your policy number and emergency centre contact details with you.
Is a Polish driving licence recognised by the police, or is an international driving permit (IDP) required?
Polish driving licences are not recognised by the local authorities. An International Driving Permit (IDP) is absolutely required. From 1 May 2021, Thailand recognises both conventions: Geneva (1949) and Vienna (1968), so both types of documents are accepted.
Not having an IDP will result in a guaranteed fine (officially up to 1,000 THB, but in practice often 500 THB) and will be grounds for the insurer to refuse to pay compensation in the event of an accident. Driving without the required licence (e.g. no category A for motorcycles >50cc) also results in the insurance company rejecting claims.
What is the cheapest way to buy a local SIM card with internet access after arriving in Bangkok?
The cheapest option is to buy a SIM card at one of the ubiquitous 7-Eleven stores or at operator outlets (AIS, TrueMove H, DTAC) in the city centre, rather than at Suvarnabhumi Airport (prices there are 30-50% higher). A passport is required to register the card.
An alternative is eSIM technology. Apps such as Airalo and Nomad allow you to purchase a data package before departure. Roaming and electronic SIM cards are slightly more expensive, but they provide internet access immediately after landing in Bangkok.
When is the rainy season in Thailand and is it safe to travel then?
The rainy season, or monsoon, occurs at different times depending on the region, and travelling during this time is completely safe, as well as cheaper and less crowded. The monsoon season usually means heavy but short rains (1-2 hours a day), rather than continuous downpours.
| Region | Peak of the rainy season | Characteristics |
|---|---|---|
| Andaman Sea (Phuket, Krabi) | May – October | Strong waves, possible restrictions on boat trips and swimming. |
| Gulf of Thailand (Koh Samui, Koh Tao) | October – December | Heaviest rainfall at the end of the year, risk of localised road flooding. |
| North (Chiang Mai) | July – September | Lush greenery, less crowded, occasional risk of landslides in the mountains. |
What are the most common scams and financial pitfalls awaiting tourists in Thailand?
The most common scams in Thailand are based on the ignorance and naivety of tourists. Knowing how con artists operate is the best way to protect your wallet and your nerves during your dream trip to Asia.
What should you do if a tuk-tuk driver claims that the Grand Palace is closed?

This is a classic “closed temple” scam, designed to take tourists to friendly shops, for which the driver receives a commission. If you hear that an attraction is closed (e.g. due to prayer) in the vicinity of the Grand Palace or Wat Pho in Bangkok, ignore it and go straight to the main entrance.
How to recognise and avoid the gem scam?

Avoid any offers to purchase gemstones as part of “special government promotions” (this is known as a Gem Scam). Fraudsters suggest that buying sapphires cheaply in Thailand and selling them at a profit in Europe is a great deal. In reality, the stones are worthless glass and the certificates are fake.
Where in Bangkok and Phuket do pickpocketing incidents most often occur?
Pickpocketing most often occurs in large crowds. In Bangkok, be especially careful in crowded places such as the BTS Skytrain queue, Khao San Road and Chatuchak Market. In Phuket, caution is advised on Bangla Road in Patong.
How much is the commission for withdrawing cash from a Thai ATM and how can it be avoided?
Fixed ATM fees for withdrawals from foreign cards are usually 220 THB per transaction. To minimise costs, withdraw the maximum possible amounts (usually 20,000 – 30,000 THB) less frequently using multi-currency cards. It is difficult to avoid the commission entirely and requires a visit to a bank branch, which is time-consuming.
Why do tourists pay more for admission to national parks (dual pricing)?
Dual pricing is an official government policy that stems from the fact that taxes paid by Thais subsidise the maintenance of parks. For example, a ticket for a Thai citizen costs 40 THB, while for a foreigner the price is 200-400 THB. Having a Thai driving licence or work permit sometimes allows you to get a lower rate.
What should you watch out for in Thai transport to travel safely and cheaply?
Chaos on the roads and high road accident statistics require special attention. Learn about the most important dangers in Thailand related to public and private transport.
What are the biggest dangers when crossing the road in left-hand traffic?
Left-hand traffic is confusing, and the habit of looking “left, right, left” is dangerous. Crosswalks do not guarantee right of way – a scooter can always pass a stationary car. Always make eye contact with the driver. In Bangkok and other large cities, motorcyclists regularly ride on pavements.
What are the most common scams when renting scooters and how can you avoid them?

Renting a scooter carries the risk of additional charges for allegedly new damage that already existed. Before leaving, make a very detailed video and photos of the vehicle (including the underside and tyres) in the presence of a rental company employee. Always check the brakes.
Is it safe to leave your passport as a deposit at scooter rental companies?
Leaving your passport as a deposit is one of the basic things not to do in Thailand. Never give it away. Offer a cash deposit (usually 3,000-5,000 THB) and a photocopy of your passport. In the event of a dispute, without your passport you are in a no-win situation.
What is the fine for riding without a helmet in Thailand and do the police often check tourists?
The fine for not wearing a helmet is officially up to 2,000 THB (in practice, tourists pay 500-1,000 THB). A protective helmet is mandatory for both the driver and the passenger. Fines are enforced on a daily basis in Thailand, especially during police raids in tourist resorts such as Phuket, Chiang Mai, Pattaya and Koh Samui.
How to effectively enforce the use of a taxi meter by a driver in Bangkok?
Always ask “Taxi meter?” before getting into the vehicle. If the driver immediately quotes a fixed, inflated price, politely decline and look for another one. Taxi meters are more likely to be turned on by drivers stopped “on the street” rather than those waiting for customers at major tourist attractions.
Are apps like Grab and Bolt a safer alternative to traditional taxis?
The Grab/Bolt app is often a safer and cheaper option. You know the price and route in advance, which completely eliminates the risk of fraud and language misunderstandings. Bolt is usually cheaper, while Grab offers more services (e.g. food delivery).
How to stay healthy in Thailand to avoid stomach problems and tropical diseases?
Food poisoning and tropical diseases are the main health risks in Thailand. Find out what diseases to watch out for in Thailand and how important prevention is, including possible vaccinations for Thailand, in consultation with a travel medicine doctor.
Is tap water in hotels in Thailand safe to drink?
Tap water is absolutely not suitable for drinking. Tap water in Thailand can be used for washing, but for drinking and brushing your teeth (especially if you have a sensitive stomach), use only bottled water, which is cheap and widely available.
Is ice in drinks and cocktails safe for tourists?
Ice cubes, usually in the form of characteristic tubes with a hole, from certified factories are safe. They are made from purified water. However, be careful with crushed ice of unknown origin, especially in small rural bars.
How can you safely eat street food without getting food poisoning?

Street food is generally safe if you choose places with high traffic and turnover (which guarantees the freshness of the ingredients). Avoid dishes that have been sitting in the sun for a long time. The safest dishes are those prepared in front of you in a hot wok.
How to effectively protect yourself from mosquitoes that carry dengue fever?
Knowing what insects to watch out for in Thailand, remember that mosquitoes carrying dengue fever are also active during the day, so protection is required around the clock. Use repellents with a high concentration of DEET (min. 30-50%) or icaridin. Wear light-coloured, loose-fitting clothing that covers the body, especially at dawn and dusk.
What are the first symptoms of sunstroke and how can it be prevented in the Thai climate?
Typical symptoms include severe headache, dizziness, hot and dry skin (no sweat). To prevent sunstroke, drink at least 3 litres of water a day, replenish electrolytes, wear a hat and avoid direct sunlight between 11:00 and 15:00.
What laws and regulations must be strictly observed in Thailand?
Thailand takes prohibitions and orders very seriously, and ignorance of them does not exempt you from criminal liability. Issues related to the monarchy, drugs and other stimulants are treated as a priority and strictly enforced.
What are the severe penalties for insulting the king and the royal family (Lese-majeste)?
Lèse-majesté is one of the most serious crimes, punishable by imprisonment for 3 to 15 years for each charge. The law is strictly enforced and applies not only to words, but also to online activity and the destruction of images of the king (e.g. on banknotes). Avoid political topics at all costs.
Is vaping legal in Thailand?
Possession and use of e-cigarettes (vaping) is strictly illegal in Thailand. It is punishable by a heavy fine (up to THB 30,000) or arrest. The equipment is confiscated at the border, so do not bring it with you.
What are the current regulations regarding the possession and use of marijuana by tourists?
Despite apparent liberalisation and the opening of numerous shops, smoking cannabis in public is punishable by law (a fine of up to 25,000 THB or up to 3 months in prison). Remember that all other drugs are strictly prohibited in Thailand, and the penalties for possession are draconian.
What are the hours during which the sale of alcohol is prohibited in 7-Eleven shops?
Alcohol and retail sales hours (such as 7-Eleven) are strictly regulated. Sales are only permitted between 11:00 and 14:00 and 17:00 and 24:00. The ban on sales also applies on certain Buddhist holidays and election days.
What cultural rules and etiquette should be observed so as not to offend Thai people?
Thailand’s rules of conduct are based on deep respect for elders, religion and the monarchy. Thai culture avoids confrontation, and the key is to “save face” (not show negative emotions in public).
How should one dress to show respect at a Buddhist temple (dress code)?

The dress code in temples requires both women and men to cover their shoulders and knees. Before entering sacred buildings, you must remove your shoes and headgear, and be careful not to stand on the threshold, which has spiritual significance in Thai culture.
Why is it forbidden to touch other people’s heads in Thai culture?
In Thai culture, the head is considered the most sacred part of the body, the seat of the soul. Touching another person’s head, even a child’s in a gesture of affection, is seen as a great faux pas and a sign of disrespect.
Why is it offensive to show the soles of your feet to people or Buddha statues?
Pointing your feet at anyone or at sacred images of Buddha is considered extremely offensive, as the feet are considered the lowest and “dirtiest” part of the body. In temples, sit with your feet facing backwards, away from the statues.
How to politely address and behave towards third gender people (Katoey)?
Ladyboys (katoeys) are an integral and accepted part of Thai society. They should be treated with the same respect as any other person. Remember that taking photos with cabaret artists usually involves an expectation of a tip.
Is it appropriate to leave tips in Thai restaurants and bars?
Tips are not mandatory, but they are welcome. In the case of street food, it is enough to round up the bill. In restaurants with waiter service, you can leave 20-50 THB. Hotels and more expensive restaurants often add a 10% service charge to the bill.
What natural and wildlife hazards should you be aware of in Thailand?
Tropical nature can be as beautiful as it is dangerous. Find out which animals to watch out for in Thailand and how to respond to potential natural hazards to ensure your trip is completely safe.
How to behave safely when encountering aggressive monkeys?

Aggressive monkeys in tourist areas associate people with food. Do not smile, showing your teeth (this is a sign of aggression to them), do not look them straight in the eye and never feed them. Keep an eye on your belongings, especially food and trinkets.
On which islands (e.g. Koh Samui) should you watch out for poisonous jellyfish (Box Jellyfish)?

Knowing what to watch out for in the water in Thailand, remember the danger posed by jellyfish. Venomous jellyfish (box jellyfish), known as sea wasps, are found in the Gulf of Thailand (e.g. Koh Samui, Koh Phangan) and the Andaman Sea. In case of a sting, immediately pour vinegar (available on beaches) on the wound and call for medical assistance.
What do red flags on beaches mean and what are dangerous rip currents?
A red flag on the beach means that swimming is strictly prohibited. What should you watch out for on a seemingly calm beach in Thailand? First and foremost, rip currents. If you feel the current pulling you out to sea, do not fight it and do not swim towards the shore. Swim parallel to the shoreline until the current weakens. Knowing what to watch out for in the sea in Thailand can save your life.
