What to know before you go
Never disrespect the monarchy
CriticalThailand has strict lese-majeste laws (Section 112): insulting the King, Queen, heir, or regent is a serious crime with prison sentences. Don't joke about, criticise, or deface images of the royal family — including on banknotes and coins, which bear the King's image. Stand still during the royal anthem in cinemas.
Return the wai correctly
ImportantThe wai (palms pressed together, slight bow) is the Thai greeting and sign of respect. Generally let the more senior person initiate, and return it with hands at chest-to-nose height. Don't wai children, waitstaff, or shopkeepers — a smile and nod is fine there.
Heads are sacred, feet are lowly
ImportantNever touch anyone's head, even a child's. Don't point your feet at people, Buddha images, or photos of the King, and don't step over someone. Point with your whole hand, not a finger, and remove or tuck your feet when sitting near a shrine.
Take your shoes off
ImportantRemove your shoes before entering homes, temples, many guesthouses, some shops, and even certain offices and clinics. Watch for a pile of shoes at the door — that's your cue. Slip-on shoes make life much easier.
Keep cool — jai yen
ImportantLosing your temper, raising your voice, or shouting in public makes you 'lose face' and is seen as deeply embarrassing in Thailand. The cultural ideal is jai yen (a cool heart). Stay calm and smiling even when frustrated — you'll get far better results.
Dress respectfully at temples
Good to knowAt temples (wat) such as Wat Pho or the Grand Palace, cover shoulders and knees — no shorts, short skirts, or sleeveless tops. Sarongs are sometimes rented at the gate. Women must never touch a monk or hand anything directly to one.
