Songkran (Thailand)

Songkran is the world's largest water fight, where Buddhist New Year transforms Thailand into a three-day celebration that outperforms #7 Venice Carnival in participation. With 4 million participants annually, the festival features water splashing symbolizing the washing away of bad luck, drawing 30% more locals and tourists than typical urban parades. Each year, over 1,000 tons of water are used in Bangkok alone, making it the planet's most immersive street event. This data-led spectacle is 20% cheaper than the average travel festival, with daily costs often under $50 for meals and activities.
