Things You Should Never Do in Thailand are not just cultural suggestions. They are boundaries you must respect to avoid offending locals, breaking the law, or putting yourself in danger. Thailand is a beautiful country with a kind and forgiving spirit, but there are clear lines you should never cross as a visitor.
You are not just exploring a new destination. You are stepping into a place where tradition, religion, and royal loyalty are deeply rooted in everyday life. What seems harmless back home might be deeply insulting here. This is not about being perfect. It is about being aware. And aware travelers are always respected in Thailand.
Things You Should Never Do in Thailand Involving the Royal Family
The Thai monarchy is not just symbolic. It is sacred. The reverence for the royal family is built into the fabric of society. Criticizing or mocking the monarchy is not just rude. It is a criminal offense under Thailand’s strict lèse majesté laws. You could be jailed for something as simple as an offhand joke or sharing a meme.

When handling Thai money, never crumple or step on it. Each banknote carries an image of the King. Even unintentional disrespect, such as using your foot to stop a falling note, could offend someone nearby and land you in trouble. During national events, such as the playing of the national anthem in malls or train stations, stop what you are doing and stand respectfully. This is not optional. It is expected.
Things You Should Never Do in Thailand at Temples and Religious Sites
Thai temples are not tourist attractions. They are sacred spaces of devotion. If you plan to visit one, dress like you respect the place. That means no shorts, no sleeveless tops, and no revealing clothes. Cover your shoulders and knees. If you do not, you may be denied entry.

Always remove your shoes before stepping inside. Keep your voice low. Never turn your back to a Buddha statue, especially when taking photos. Avoid selfies altogether in these sacred spaces. Do not climb or touch statues under any circumstance.
Your feet should never be pointed toward a Buddha image. This is seen as the ultimate disrespect. When sitting, fold your legs to the side or tuck them behind you. Do not rest your feet on ledges or furniture. If a monk is present, especially during a ceremony, sit lower than him and avoid physical contact. Women should not touch monks at all. This includes handing objects directly to them.
Things You Should Never Do in Thailand in Public Spaces
Public behavior in Thailand reflects the importance of keeping face. Shouting, swearing, or showing anger in public makes you appear ignorant and disrespectful. It will never help your situation and might escalate it.

Public displays of affection should be minimal. Holding hands is acceptable in most places, but kissing or hugging in public, especially near temples or local markets, is considered inappropriate.
The head is the most sacred part of the body in Thai belief. Never touch anyone’s head, not even a child’s, no matter how cute they are. And never use your feet to point at people or move objects. Doing so signals total disrespect.
Things You Should Never Do in Thailand Regarding Culture and Customs
The Thai greeting, called the wai, involves pressing your palms together in front of your chest and bowing slightly. If someone offers you a wai, especially someone older, return it respectfully. It is not just a hello. It is a gesture of respect.
Avoid whistling at night. Many Thais believe it invites bad spirits. Avoid discussing the monarchy, politics, or religion in casual conversation unless you deeply understand the culture. It is safer to listen than to speak on such topics.

When invited into a Thai home, take off your shoes before entering. It is a basic sign of respect. Never blow your nose loudly in public or while eating. It is seen as rude and unsanitary.
Things You Should Never Do in Thailand When Partying or Drinking
Thailand’s nightlife might be wild and vibrant, but the rules behind it are strict and sometimes unspoken. Drinking alcohol under the age of 20 is illegal, even if you are a foreigner. Never try to bribe your way out of trouble.
Do not drink alcohol during religious holidays. It is prohibited and bars often shut down without notice. Always check before going out.

Smoking in restricted areas, including many beaches, carries a heavy fine. Drug use of any kind is extremely serious. Even possession of a small amount can lead to years in prison or worse. Do not carry, buy, or accept drugs in Thailand. The law is unforgiving.
Things You Should Never Do in Thailand in Wildlife and Tourism
The beautiful photos you see of tourists riding elephants or petting tigers often come with a dark reality. Many of these animals are abused, drugged, or kept in poor conditions for entertainment. Supporting these places keeps the abuse alive. Choose ethical sanctuaries that prioritize animal welfare.
Do not collect or buy Buddha statues as souvenirs unless they are small and clearly for decorative purposes. Taking large Buddha images out of the country without permission is illegal.
Respect nature. If you visit national parks or beaches, do not litter. Thailand takes environmental conservation seriously, and disrespecting natural places is both socially and legally frowned upon.
Things You Should Never Do in Thailand as a Foreigner or Tourist
Immigration rules in Thailand are not to be played with. Never overstay your visa. Even a single day can cause complications when you try to exit the country or return in the future.
Always carry identification. A copy of your passport will suffice in most cases. You may be stopped at checkpoints, especially in tourist-heavy areas. Be polite and cooperate if asked.
Learn basic Thai phrases. A simple “sawasdee” (hello) or “khob khun” (thank you) can win you smiles and soften tense situations. Remember, the Thai way is calm, graceful, and non-confrontational. If you carry yourself that way, you will be welcomed everywhere you go.
Thailand is not just a destination. It is a deeply spiritual and proud society. Being a tourist does not exempt you from understanding or respecting the customs. In fact, the more you learn before your trip, the richer your experience becomes. The things you should never do in Thailand are not meant to restrict you. They are meant to open the door to deeper connection and mutual respect. Be more than a visitor. Be a responsible guest.
