Songkran (Thai New Year Water Festival)

Songkran immerses participants in the world's largest water fight, drawing over 2 million travelers annually. Each April, citywide battles transform streets into festive aquatic arenas, with temperatures reaching 38°C intensifying the relief. This celebration outperforms #2 Loy Krathong in global participation, as its week-long schedule delivers 30% more tourist spending than the typical Thai festival.
