Naga Fireball Festival
One of the world's most awesome phenomena is this natural event which coincides with the end of the Buddhist Rains Retreat. Hundreds, often thousands of balls of fire rise out of the water to a few hundred metres before disappearing. It is not yet known how exactly this occurs and though scientists may dispute, the locals believe it is the work of Naga, a serpent living in the Mekong River. There is an annual festival to celebrate this intriguing phenomenon.
Venue: Mekong River, Nong Khai region
Date: 26 - 27 October 2014
