Loy Kratong in Chiang Mai has the added feature of a parallel festival called Yi Peng. Yi Peng is celebrated by launching hot air balloons (Khom Fai) made of rice paper into the night sky. The night sky is literally filled with thousands of these bright lights shining like a moving river of stars. It's a truly magical sight of a scope that can't fully be captured in a picture. Yi Peng is held at Lumpini Park in Chaing Mai near the start of Loy Kratong Festival.
