"One of Thailand's significant festivals", the Loi Krathong event is held nationwide beneath the full November moon when the water level in the rivers and canals reach their full height. Specially decorated krathongs (banana-leaf floats) full of flowers, incense and one or more lit candles are placed in the water and released to the current, creating a picturesque glittering scene against the backdrop of the river. The festival is believed to have been held since the Sukhothai era. There is an annual celebration organized at Sukhothai historical Park featuring the floating of krathongs, a fireworks display and cultural performances.
