On the full-moon night of the twelfth Thai month, people float candlelit krathongs on the river to thank the water and send their troubles away.

Know before you go

  • Don't use polystyrene krathongs
  • don't release sky lanterns outside designated areas — they endanger flights and houses
  • don't push on riverbanks, and with big crowds at night, be careful not to fall in

Background

Loy Krathong is held on the full-moon night of the twelfth month of the Thai calendar, usually in November. People make krathongs from banana-tree trunks, banana leaves and flowers, add candles and incense and float them on rivers and lakes, thanking the water for its nourishment and asking it to carry away bad luck. Chiang Mai holds the Lanna Yi Peng sky-lantern festival at the same time, and Sukhothai Historical Park has candle and light shows.

Local customs

  • Put your palms together and make a wish before floating your krathong
  • couples often float one together
  • in Chiang Mai, sky lanterns may only be released at the places and times set by the organisers

Religion & beliefs

  • A blend of Buddhism and reverence for water
  • temples light lamps to honour the Buddha.
