"The Candle Festival" is one of I-san's Heet Sip Song local customs. The event is held a day before Buddhist Lent and is celebrated by staging a parade of elaborately carved beeswax candles around the city before presenting them to local temples. Monks residing in the temples use these candles to pay respect to the Lord Buddha and to study his teachings throughout the Buddhist Lent. The most magnificent Candle Festival is held in Ubon Ratchathani province.
