Need to know
Don't listen to anyone on the street as you try to enter telling you it's closed for a 'Buddhist holiday', 'cleaning' etc, or asking if you want to see the 'Lucky Buddha' instead - it's all part of a sophisticated gem scam.
As Wat Phra Kaew is Thailand's most important temple, you are expected to dress appropriately or risk being turned away. Signs put up around the entrance show you are not permitted to enter wearing shorts, sleeveless shirts, singlets or any form of open ended shoes. Sarongs and long trousers are usually available for loan should you forget.
