Songkran celebrates the traditional Thai New Year. Chiang Mai celebrates Songkran with special elation in a 3-day carousal of religious merit-making, pilgrimages, beauty parades, dancing and uninhibited, good-natured water throwing. It is held during April 13-15. Songkran, the traditional Thai New Year, is celebrated all over the country but nowhere with more enthusiasm than in Chiang Mai. Part of the celebration is religious, marked by merit-making ceremonies at local temples and part is pure pleasure, with good natured water throwing, parades, and beauty contests.
Yi Peng Loi Krathong is Thailand's loveliest festival. Under the full moon, on lakes, rivers, streams, ponds and klongs, people float banana-leafboats bearing lighted candles, incense, flowers and small coins to honor water spirits and float away the past year's sins. It is held every November. In Chiang Mai , an unusual part of the Loi Krathong celebration is the Yi Peng Loi Festival or the ritual of the lighted balloon. After a day of merit-making, people launch colorful hot air paper balloons into the sky, carrying their troubles away. In the evening, all homes and shops are decorated with beautiful lanterns. Later, traditional Krathongs are also floated on the river and other waterways.
