Dress code
The standard rule at Chiang Mai's temples, including Wat Phra That Doi Suthep, Wat Chedi Luang and Wat Phra Singh, is shoulders and knees covered for everyone, regardless of gender. Sleeveless tops, shorts and short skirts are generally considered inappropriate for the inner temple buildings. Many temples have sarongs available to borrow or rent at the entrance, but it's simpler to dress appropriately from the outset, especially at Doi Suthep where you'll also be climbing stairs in the heat.
Shoes
Shoes come off before entering viharns (assembly halls) and other interior temple buildings — look for the piles of shoes at the entrance as your cue, and slip-on footwear makes this a lot easier over a day of temple visits.
Inside the temple
- Keep your voice down and movements calm, particularly if a ceremony or prayer session is underway.
- Avoid pointing your feet toward Buddha images or monks — if sitting, tuck your feet behind you rather than crossing them forward.
- Women should avoid physical contact with monks, including passing objects directly hand to hand.
- Ask before photographing monks or people praying — a temple's architecture is fair game, but treat people with the same courtesy you'd want yourself.
Wider cultural notes
The wai — a slight bow with palms pressed together — is Thailand's traditional greeting; you don't need to master it, but a returned wai is always appreciated. The Thai royal family is held in very high regard, and public criticism is best avoided entirely. Raising your voice or showing visible anger in a public dispute is culturally frowned upon and rarely helps resolve the situation anyway — a calm, friendly approach goes a long way in Thailand generally.
