Naga Fireball Festival in Nong Khai
The Naga Fireball Festival in Nong Khai centers on bang fai phaya nak, glowing reddish orbs said to rise naturally from the Mekong River, most often reported on the night of Wan Ok Phansa in late October, and celebrated locally as evidence of a giant serpent believed to inhabit the river.
The Naga Fireball Festival takes its name from a genuinely mysterious phenomenon reported along the Mekong River for generations: glowing, reddish orbs, ranging from small sparkles to objects the size of basketballs, said to rise naturally from the water and drift a couple hundred meters into the air before disappearing.
